Synopsis

I. Introduction

1. In this Report and Order, the Commission adopts new licensing,
service, and technical rules for three bands. In so doing, the
Commission attempts to follow a consistent framework across all of the
bands that can serve as a template for additional bands in the future.
The Commission adopted 10 year license terms and performance
requirements that are flexible to allow multiple use cases to evolve
over time. These basic building blocks are modified in order to meet
the specific characteristics of a particular band.
2. The Commission also took significant steps forward on solutions
to spectrum sharing in the millimeter wave (mmW) bands. The Commission
adopted rules that will allow both satellite and terrestrial networks
to continue to expand in a flexible manner. The Commission continues to
facilitate co-primary shared access to the 39.5-40 GHz band for Federal
and non-Federal users, and building off of recent policy developments
in spectrum sharing, it also created a new approach to Federal sharing
in the 37 GHz band. Specifically, instead of relying on static
exclusion zones, the Commission created a space for both Federal and
non-Federal users to share on a coequal basis and set out a process for
defining how that sharing will be implemented. Finally, the Commission
substantially increases the amount of unlicensed spectrum available by
adding another seven gigahertz to the existing 57-64 GHz band, and
adopting flexible technical rules.

A. 28 GHz Band

1. Suitability for Mobile Use
3. Some satellite operators, satellite equipment suppliers and
satellite-focused trade associations urge the Commission not to
authorize terrestrial mobile services in the 28 GHz band. This
perspective is by no means unanimous or unqualified even among that
group, however. SES, for example, says that it expects to support
terrestrial mobile services in bands above 24 GHz by providing video
distribution, providing backhaul services, and by extending terrestrial
network coverage to sea, air, and remote land masses. EchoStar says
that satellite operators could coexist with mobile services in the band
by avoiding deployment of gateway earth stations in large urban
centers. ViaSat estimates that the compatibility distance between
satellite earth stations and terrestrial mobile in the 28 GHz band
would be in the range of 160 meters, and could be further reduced by
additional mitigation techniques. Nearly all other commenters who
address the topic emphatically support mobile service authorization in
the 28 GHz band.
4. Perhaps more so than other mmW bands, the 28 GHz band has been
the focus of academic research and industry prototyping efforts to
develop mobile service technologies. The 28 GHz band is attractive for
research on enabling mobility in mmW bands because, with 850 megahertz
of contiguous bandwidth, it has ample capacity to accommodate a wide
range of high data-rate applications, and it has global co-primary
allocations for fixed and mobile services. There are no Federal
allocations in the band. Further, because this is an active service
with Local Multipoint Distribution Service (LMDS) licenses covering
about 75 percent of the U.S. population, it can be quickly repurposed
for new flexible uses, including mobile. The ready availability of the
spectrum will also help drive the development of a robust ecosystem at
a large scale.
5. Opponents of authorizing new flexible and mobile use in the 28
GHz band raise three basic objections: (1) That there is no
international consensus to authorize mobile services in the band; (2)
that LMDS operators do not have an equitable expectation of mobile
rights in the band; and (3) that mobile services in the 28 GHz band
would impair vital satellite services. The Commission discusses the
first of those issues below, reserving discussion of the second and
third issues for Section I.4.c (Aggregate Interference to Satellite
Receivers).
6. Regarding the alleged absence of international consensus
expressed by some of the commenting parties, the Commission notes that
the 28 GHz band already has a primary worldwide mobile service
allocation, which embodies a previously agreed consensus among
International Telecommunication Union (ITU) members. Although World
Radiocommunication Conference (WRC) 2015 (WRC-15) omitted 27.5-28.35
GHz from a list of mmW bands that it invited ITU-Radiocommunication
(ITU-R) to study for mobile service, the record in this proceeding
makes it abundantly clear that there are significant benefits to
authorizing mobile use in the 28 GHz band regardless of that
international decision.
7. Administrations and wireless industry representatives that have
been major leaders in the mobile industry support authorization of
mobile services in the 27.5-28.35 GHz band. Verizon notes that
countries supporting mobile use in the band include South Korea, Japan,
Sweden, Finland, and Singapore--``technology powerhouses with their
sights set on 5G''--and argues that this Commission should not delay
repurposing the 28 GHz band while its counterparts in those countries
support their industries' efforts to develop mobile technologies for
the band. Intel says that major markets like the U.S., Japan, and Korea
are moving expeditiously, ``blazing the trail for mobile 5G services in
the 28 GHz band, in spite of the WRC-15 decision not to study the 28
GHz band leading up to WRC-19.'' Ericsson contends that, regardless of
the outcome of WRC-15, spectrum from this general range very likely
will be used for 5G around the world, as evidenced by the fact that
Japan and Korea appear to be pressing ahead to use frequencies in this
range for their Olympic Game deployments. Nokia expresses
disappointment with the outcome of WRC-15, sees ``great potential'' for
the 28 GHz band and urges the Commission to ``unlock the promise of
that band for mobile use.'' Internationally, Huawei and Alcatel-Lucent
are also focusing on the 28 GHz band as key spectrum for mobile use. T-
Mobile USA, whose majority owner is the flagship German
telecommunications company, Deutsche Telekom, filed comments in this
proceeding expressing its support for mobile services in the 28 GHz
band. Other comments reflect near-unanimous support among carriers,
equipment suppliers, and associations that represent them.
8. The Commission acknowledges the comments of parties that
emphasize the importance of international harmonization, but in this
case, it appears there is sufficient international interest (including
from Japan and South Korea) for using the 28 GHz band and adjacent
bands to justify making the 28 GHz band available for mobile use. Intel
and Ericsson both state that the

[[Page 79896]]

mobile industry could readily create integrated circuits with tuning
ranges for various bands in that part of the spectrum, and the Republic
of Korea submitted a proposal to WRC-15 stating that the ``frequency
range from 24.25 GHz to 29.5 GHz proposed from regional groups could be
implemented by one single device to facilitate global roaming around
the year 2020.'' These kinds of capabilities are already being
reflected in standards development. Microsoft explains that 3GPP
release 13 will allow for carrier aggregation of multiple bands of
spectrum, both licensed and unlicensed, in the 5 GHz band, and it says
that, once 5G service is defined, the committee will likely extend its
standards to encompass the millimeter wave bands. Microsoft argues that
carriers should ultimately be able to aggregate low-, medium-, and
high-band spectrum. The significant domestic and international interest
in making the 28 GHz band available for new mobile uses clearly
supports taking action in this Report and Order to create new flexible
use licenses.
2. Licensing the 28 GHz Band
a. Use of Geographic Area Licensing
9. The Commission adopted its proposal to implement geographic area
licensing throughout the 28 GHz band because geographic area licensing
will expedite deployment, provide licensees with the flexibility to
provide a variety of services, and is consistent with the existing
licensing scheme. One significant advantage to this approach is that
the Commission can expedite use of the band for advanced services
because it is consistent with the existing framework in this band.
10. In contrast, if the Commission adopted a separate framework for
mobile use of the band, the Commission needs to develop a Spectrum
Access System (SAS), define the specific rights held by the existing
licensees, and work out rules for coordination with the existing
licensees. Adopting geographic area licensing for this band is also
consistent with the Commission's goal of adopting a balanced licensing
approach that includes licensed, unlicensed, and innovative sharing
approaches across a variety of bands. For these reasons, the Commission
is not adopting a 3.5 GHz-style SAS framework for this band.
11. Similarly, the Commission declines to adopt Microsoft's
proposal to create an unlicensed portion of the band. The Commission
believes splitting the band into unlicensed and licensed segments would
potentially hinder deployment by making it more difficult for licensees
to use the full 850 megahertz of spectrum. The Commission nonetheless
agrees that a balance between licensed and unlicensed usage is
important, and as described below, the Commission is also making seven
gigahertz of spectrum available for use by unlicensed devices in the
64-71 GHz band, and create an opportunity for shared access in the 37-
37.6 GHz band segment.
b. License Area Size
12. The Commission adopted counties as the license area size for
Upper Microwave Flexible Use Service (UMFUS) licenses in the 28 GHz
band. The Commission also adopted its proposal to subdivide existing
LMDS licenses on a county basis. As the Commission explained in the
Notice of Proposed Rulemaking (NPRM), a county-based license affords a
licensee the flexibility to develop localized services, allows for
targeted deployments based on market forces and customer demand, and
facilitates access by both smaller and larger carriers. In the
Commission views, the claims of certain commenters that larger license
areas will better fit the services contemplated for these bands lack
specificity and do not take into account the potential need for
targeted deployment. It is unclear that providers need to--or will want
to--aggregate nationwide licenses, as mobile operations in the band may
initially be deployed. On a mobile basis, this band is envisioned for
mobile operations in denser population centers or around highway
corridors. While it is true that county-sized licenses will result in
more borders, the Commission adopted a power flux density (PFD) limit
at the border that will facilitate coordination between licensees.
Furthermore, no party offered evidence that there have been problems
providing service near existing Basic Trading Area (BTA) borders. The
Commission notes that licensees in other services regularly coordinate
their operations along shared borders and have well established
procedures for conducting this coordination. The Commission expects
that licensees will be able to apply these same procedures in this band
without any undue burden. To the extent existing BTA licensees do not
believe it is economically viable to build within certain counties of a
BTA, the Commission believes it would be appropriate to give other
interested parties an opportunity to license and to make use of the
spectrum. Finally, establishing smaller license areas is fair to
existing licensees because those licensees are also obtaining valuable
new rights and they are keeping the same bundle of rights they had
previously. Overall, the Commission believes the benefits of smaller
license areas for this specific band outweigh any administrative burden
on licensees and the Commission.
13. In this proceeding, the Commission is endeavoring to create a
regulatory scheme that will suit the development of innovative wireless
services for years to come. The Commission in recent years has sought
greater consistency in its approach to geographic license area sizes to
help providers aggregate licenses in a more targeted and efficient
manner, gravitating toward license areas that are derived from Economic
Area (EA) units. BTAs have only been used as the license area for a few
commercial wireless services. Counties, however, are the base unit that
make up common commercial wireless license sizes, including EAs and the
new Partial Economic Area (PEA) license areas. There is also a
practical advantage to issuing county-based licenses. Specifically, the
Commission would be required to negotiate a new licensing agreement
with Rand McNally to use BTAs in UMFUS. In recent years, the Commission
has avoided using license areas controlled by third parties in order to
eliminate the time and expense involved in negotiating such agreements.
3. Mobile Rights for Incumbents
14. The Commission adopted its proposal to grant mobile operating
rights to existing active LMDS licensees. This grant is in fulfillment
of the Commission's original mobile allocation for 28 GHz and its
stated expectation of allowing mobile use in the band in ``providing
LMDS licensees with maximum flexibility in designing their systems.''
The Commission adopted the rules; therefore, licensees are able to
provide mobile services consistent with part 30 licensing and technical
rules. Granting mobile operating rights to existing licensees will
expedite the deployment of service, minimize the difficulties involved
in coordinating fixed and mobile deployments, and provide a uniform
licensing scheme throughout the United States. The Commission remains
concerned that awarding fixed and mobile rights separately would lead
to disputes between fixed and mobile licensees that could make it more
difficult for both licensees to provide service.
15. The Commission recognizes that awarding mobile rights to
incumbent licensees could be viewed as a windfall to those licensees,
although the

[[Page 79897]]

Commission contemplated granting mobile rights when it first created
LMDS. Here, the benefits of expediting service and ease of coordinating
fixed and mobile service outweigh any foreseeable disadvantages of
granting mobile rights to incumbents. In this instance, the Commission
finds that expedition is particularly important because of the need to
make mmW spectrum available for innovative and novel issues.
4. Satellite Terrestrial Sharing
a. Sharing With FSS (Fixed Satellite Service) Earth Stations
16. The record demonstrates that FSS earth stations in the 28 GHz
band can share the band with minimal impact on terrestrial operations.
For example, EchoStar argues that 28 GHz Earth-to-space stations would
not curtail the deployment of 5G systems outside a few very small non-
urban areas. EchoStar and ViaSat both estimate that terrestrial mobile
stations could be deployed as close as 170 meters to their Earth-to-
space transmitters in the 28 GHz band. SES Americom suggests ``carving
out some rural areas where future gateway earth stations can be
licensed for use in the 28 GHz band.'' With respect to terrestrial
operations, AT&T, Nokia, Samsung, T-Mobile, and Verizon estimate that
the necessary separation distances between FSS earth stations and
terrestrial deployments are between 50 and 400 meters depending on the
type of earth stations. Therefore, the Commission finds that it is in
the public interest to create rules that allow for continued and
expanded sharing between terrestrial operations and FSS earth stations
in the 28 GHz band.
17. The Commission recognizes that sharing may be more difficult
for non-geostationary satellite systems, such as the system operated by
O3b. While O3b argues that it needs multiple sites in a county in order
to serve customer locations, it ignores the Commission's decision that
it was allowing FSS to access the 28 GHz band solely for the purpose of
providing limited Earth-to-space gateway-type services. O3b had no
reasonable expectation that the Commission would grant earth stations
designed to serve customer locations priority over fixed LMDS services
and mobile services that the Commission contemplated would become part
of LMDS. O3b estimates that the preclusive distance for its gateway
earth stations with respect to mmW mobile stations is between 1.2 and
13.8 kilometers. Nonetheless, the Commission believes that sharing is
feasible for O3b. First, as discussed below, the Commission is
grandfathering O3b's existing earth stations in Texas and Hawaii.
Second, O3b has the option of locating future earth stations in
relatively remote areas. Third, O3b can obtain protection by purchasing
an exclusive use terrestrial license at auction or by working with a
licensee in the secondary market to partition a license area with
sufficient size to allow it to deploy additional earth stations without
impacting terrestrial operations, or enter into a different type of
negotiated sharing arrangement. Fourth, O3b can take advantage of
shielding or other mitigation techniques. Comsearch characterizes
satellite operators' use of naturally occurring terrain features as
follows:

Before the great explosion of satellite communications for all
types of uses, earth station sites were carefully selected with
protection from interference the primary consideration. Most
locations were many miles from the cities that they were serving,
with the ideal earth station site being naturally shielded by
terrain at a spot, which was calculated to be virtually free of
interfering signals. For most types of communication, this type of
isolation is not required, although it is still true that the most
important aspect of a site is its shielding.

There are many naturally occurring terrain features that are
capable of providing terrain shielding for NGSO gateway stations and
shielding can also be provided by creating berms or other man-made
barriers.
18. In short, while allowing new earth stations in the 28 GHz band
is not without cost to terrestrial licensees, the Commission believes
that the small area encumbered by a new earth station (with the limits
noted below) will minimize such costs and will allow both satellite and
terrestrial services to expand and coexist. Furthermore, satellite
operators deployed in this band knowing that they were secondary
licensees with respect to LMDS, that the Commission had chosen to allow
only limited satellite use, and that the Commission had long envisioned
allowing mobile use in the band. Despite these facts, below the
Commission creates a path to further expand satellite gateways that
could add thousands of new sites because the Commission believes the
relatively small protection zones will have little impact on
terrestrial use.
b. Licensing of FSS Earth Stations
19. The Commission maintains the current status of FSS, and as
described below, creates new opportunities for continued expansion of
FSS earth stations on a protected basis. Upgrading the FSS designation
to co-primary status, even if limited to individually licensed earth
stations, would be inconsistent with terrestrial use of this band and
the Commission's decision to facilitate expanded terrestrial use, and
would not effectively facilitate sharing in the band. The Commission
believes the 28 GHz band will play a vital role in the deployment of
advanced mmW services, and fully upgrading FSS under the Commission's
service rules to co-primary status would be inconsistent with this goal
and would be unnecessary to meet the FSS community's needs.
20. The Commission recognizes, however, that FSS operators rely on
this band for gateway connectivity and have invested significant
capital in the band and will continue to do so in the future. The
Commission believes there is value in creating meaningful, targeted
opportunities to deploy additional FSS earth stations in the band
without harming terrestrial operations. The NPRM's proposals
encouraging satellite operators to participate in county-sized (or
smaller) market transactions were predicated in part on the vast
protection zones that satellite operators have traditionally claimed
were necessary, either to protect their operations or to protect others
from them. Here, there is a consensus that much smaller protection
zones are needed. EchoStar and ViaSat have both estimated that
terrestrial mobile stations could be deployed as close as 170 meters to
their Earth-to-space transmitters in the 28 GHz band. Most other
satellite operators either support those specific calculations, agree
in general terms that the necessary preclusive zones can be very small,
or state that gateway earth stations can be located in rural areas far
away from the urban cores where mmW mobile operations will be most
viable.
21. The ability of satellite earth stations and terrestrial
operations to coexist in close proximity to each other has two
significant ramifications. First, it should be possible for satellite
and terrestrial services to share the 28 GHz band with de minimis
impairment of each other's operations. Second, the disparity between
the county-sized license areas the Commission has established for 28
GHz UMFUS licensees and the extremely small areas required for FSS
earth stations makes it inappropriate for the Commission to rely
exclusively on a market-based mechanism for assigning rights to FSS
earth stations, although the Commission retains this option as one
means through which FSS operators may expand.
22. In addition to acquiring the terrestrial license rights, the

[[Page 79898]]

Commission also concludes that it would be efficient to continue to
authorize gateway satellite earth stations under the existing part 25
first-come, first-served basis. The Commission adopts a mechanism under
which FSS earth stations will, so long as they comply with conditions
noted below, be able to deploy new gateways in limited circumstances
without being required to take any additional actions to provide
interference protection to UMFUS licensees. The Commission builds this
upon record support for several different approaches to sharing in the
28 GHz band.
23. The authorization of FSS earth stations in the 27.5-28.35 GHz
band that will not be required to take any additional actions to
provide interference protection to UMFUS licenses is subject to the
following conditions. First, the Commission will authorize no more than
three locations in each county where FSS may deploy earth stations on a
protected basis. Second, an FSS applicant must demonstrate in its
license application that the permitted interference zone around its
earth station, which the Commission will define as the contour within
which FSS licensees generate a PFD, at 10 meters above ground level, of
no more than -77.6 dBm/m\2\/MHz, together with any preexisting earth
stations located in the same county on a protected basis, will, in the
aggregate, cover no more than 0.1 percent of the population of the
county license area where the earth station is located.\1\ Third, the
applicant must show that the permitted interference zone does not
infringe upon any major event venue, arterial street, interstate or
U.S. highway, urban mass transit route, passenger railroad, or cruise
ship port. The Commission notes that Verizon supports prohibiting
siting earth stations near athletic and/or entertainment venues,
interstate and U.S. highways, and port facilities. The Commission
believes the other locations the Commission has identified are
similarly areas where the Commission could expect to have high demand
for wireless services. Fourth, prior to filing its application, if
there is an existing 28 GHz UMFUS licensee in the county where it is
proposing to locate its earth station, the earth station applicant must
coordinate its operation with the existing UMFUS licensees using the
coordination procedures contained in Sec. 101.103(d) of the
Commission's rules. The purpose of the coordination is to ensure that
the earth station will not interfere with existing facilities operating
under the UMFUS license. The Commission expects that UMFUS licensees
will cooperate in good faith in the coordination process and only raise
objections if there is a legitimate concern about interference to
existing UMFUS facilities or failure to comply with the criteria listed
above.
---------------------------------------------------------------------------

\1\ The International Bureau will issue a public notice seeking
comment on the appropriate methodology to calculate the 0.1 percent
population limit and further details regarding earth station
interference zone calculation (including propagation models, e.g.
free space versus probabilistic), and will also seek comment on best
practices for earth station siting to minimize the impact on UMFU
services, colocation of earth stations, and accommodating multiple
earth station interference zones without exceeding 0.1 percent of
population in a given county.
---------------------------------------------------------------------------

24. These conditions are designed to provide FSS licensees with
substantial opportunities to expand their limited use of the 28 GHz
band to deploy earth stations that do not have to protect terrestrial
services, while minimizing the impact on terrestrial operations. Since
there are over 3,000 counties in the United States, with a potential
for up to three locations in each county, FSS licensees would have many
choices for earth station locations. Furthermore, even with the
conditions the Commission has imposed, FSS operators will have great
flexibility in selecting earth station locations that meet their needs.
Taking ViaSat's 160-meter radius estimate as a point of departure, the
typical interference zone for terrestrial operations around a gateway
earth station would cover about 0.08 square kilometers. As ViaSat
notes, this zone could be reduced further by reducing the preclusive
distance around the earth station, using mitigation techniques such as
shielding. Even without such reductions, the interference zone would
represent only about 0.0033 percent of the area of an average U.S.
county. If one were to assume an even population distribution
throughout every county, ViaSat's interference zone would cover no more
than 0.1 percent of the population of any county that covers more than
80 square kilometers. There are only four counties in the United States
that cover less than 80 square kilometers. In addition, any
interference zone will be allowed to accommodate multiple FSS earth
stations that could, for instance, be serving different satellites in
the geostationary orbit, as long as these earth stations, in the
aggregate, do not cause the interference zone to exceed the limits the
Commission adopted in this Report and Order.
25. Conversely, the Commission believes that allowing FSS earth
stations to share the 28 GHz band under these conditions will not
unduly hinder terrestrial deployment in the band. The Commission notes
that existing LMDS licensees are obtaining valuable mobile rights, and
the value of those rights far outweighs any impairment imposed by this
sharing mechanism. In addition, under the rules the Commission adopted,
the Commission believes that FSS operations will encumber only a small
geographic area and a small portion of the population of the license
area. While the Commission maintains flexibility for FSS operators to
choose the areas that fit within these conditions, current and future
licensees will have some ability to predict the potential impact on the
license area.
26. Other than applying those conditions, the Commission does not
propose to designate the locations of any county's satellite permitted
interference zones in advance--i.e., the Commission will leave the
choices of locations to the discretion of the satellite operators,
conditional upon the licensees constructing and activating their earth
stations within 12 months, pursuant to Sec. 25.133 of the Commission's
rules.
27. The Commission also notes that FSS operators will have other
mechanisms available to deploy earth stations that do not have to
protect terrestrial services. The Commission will adopt its proposal to
grant such rights to any FSS earth stations for which the FSS operator
also holds the UMFUS license that covers the earth station's permitted
interference zone. To the extent FSS operators and UMFUS licensees
enter into private agreements, their relationship will be governed by
those agreements. Finally, FSS earth stations may continue to be
authorized without the benefit of an interference zone. In this
respect, taking into account the small size of the area around an earth
station where terrestrial operations would not be protected, the
Commission encourages UMFUS licensees to be flexible in providing
certainty to the operation of FSS earth stations in areas where they do
not intend to deploy terrestrial services. The Commission emphasizes
that these FSS earth stations will have no expectation of interfering
rights and will have to cease operation if requested by UMFUS licensees
at any time on the basis of harmful interference to their services.
28. The Commission also modifies its proposal in the NPRM for
treatment of existing FSS gateway earth stations. Since the Commission
is no longer requiring FSS operators to obtain an UMFUS license in
order to obtain the right to interfere, the Commission will not grant
UMFUS licenses to existing FSS earth station holders. Instead, the
Commission will grandfather all

[[Page 79899]]

existing 28 GHz FSS earth stations authorized as of the adoption date
(July 14, 2016) of this Report and Order and grant them the right to
operate under the terms of their existing authorizations without taking
into account possible interference to UMFUS operations. The Commission
will also grandfather pending applications for 28 GHz earth stations
filed prior to the adoption date of this Report and Order if such
applications are subsequently granted pursuant to the existing part 25
rules (i.e., without regard to the criteria the Commission adopted).
The Commission notes that in many instances, these earth stations are
used to provide valuable services to customers. In areas where there is
no existing LMDS licensee, a new UMFUS licensee will have the ability
to take the existing FSS earth station into account before it acquires
the license or plans deployment. Even in areas where there is an
existing LMDS licensee, Samsung's analysis demonstrates that existing
earth stations will have a small impact on the terrestrial licensee.
Finally, the Commission notes that AT&T and Verizon support
grandfathering existing earth stations.
29. In adopting these rules, the Commission acknowledges with
appreciation the efforts that AT&T and EchoStar have made to forge a
compromise proposal that would be acceptable to other parties. The
Commission declines to adopt their compromise proposal because it would
have provided less predictability regarding the locations of future
earth stations, and it would have limited the ability of FSS to deploy
near population centers even if the deployment affected a small
percentage (or even none) of the population. By contrast, the sharing
mechanism that the Commission adopted will provide predictability to
terrestrial licensees while giving FSS the opportunity to greatly
expand their operations to over 9,500 locations. The Commission
believes the rules that the Commission adopted will encourage intensive
use of the band by both UMFUS and FSS licensees.
c. Aggregate Interference to Satellite Receivers
30. The second issue that must be considered with respect to
satellite-terrestrial system coexistence is aggregate skyward
interference to satellite receivers. There is a concern on the record
that upward transmissions from large numbers of terrestrial stations
will, in the aggregate, generate enough power to be received at the
satellite's receiver, thus degrading the satellite's performance. The
most detailed concerns about aggregate interference are raised in ex
parte presentations by O3b, SES, ViaSat, and a group referring to
themselves as Satellite Operators. For the reasons noted below, the
Commission concludes that the potential for aggregate interference
rising to the level of harmful interference is unlikely and thus is not
a basis for refusing to authorize mobile service in the 28 GHz band,
and the Commission declines to establish any regulatory limit on
aggregate power levels.
31. Under the Commission's rules, FSS is secondary to LMDS fixed
and mobile operations in the 28 GHz band. The Commission's rules
specifically state, ``FSS is secondary to LMDS in [the 27.5-28.35 GHz]
band.'' Internationally, this band is allocated to the FSS and the
fixed and mobile services on a co-primary basis. The Commission
recognizes that there are non-U.S. licensed FSS networks in this band,
and that the United States needs to protect those systems consistent
with its relevant international obligations. This framework exists in
other bands where FSS shares spectrum with terrestrial services
internationally, such as the C-band. Contrary to Lockheed Martin's
assertions, the Commission is not violating U.S. international treaty
obligations by adopting rules that will enable the provision of UMFUS
in the 28 GHz band without first resolving potential aggregate
interference issues. As discussed below, the Commission concludes that
the risk of aggregate interference is low. In the event, however, that
there is an instance where a non-U.S.-licensed FSS network receives
harmful interference, the Commission intends to address such
interference in accordance with applicable U.S. international treaties,
and will monitor industry developments to that end. The Commission
rejects ViaSat's argument that the Commission granted FSS primary
status over mobile operations. ViaSat relies in part on the following
passage from the LMDS First Report and Order:

We are designating discrete spectrum bands for specific types of
systems. Services designated for domestic licensing priority are
specified in capital letters in the graphic depiction of the band
plan. These services have licensing priority vis-[agrave]-vis any
other type of service allocated domestically or internationally in
the band. Lower-case letters indicate services in a particular band
segment which also have licensing priority vis-[agrave]-vis any
third service allocated domestically or internationally in the band,
but have no licensing priority over the service in capital letters
in the band segment and must operate on a non-interference basis and
must accept interference vis-[agrave]-vis that service.

Contrary to ViaSat's view, the Commission can, and in fact did,
establish priority for mobile services through its service rules.
ViaSat claims that FSS retains primary status over any new mobile
service, because the Commission established priority only for LMDS.
This argument fails because mobile service is part of LMDS, and is not
a ``third service'' or a ``new service.'' The mobile allocation already
existed at the time of the LMDS First Report and Order, but the
Commission made no distinction between fixed and mobile service in
terms of priority--it established priority for a terrestrial service
over a satellite service. The Commission contemplated that LMDS, the
designated primary service, could eventually obtain mobile rights.
Indeed, it ``kn[e]w of no reason why we would not allow mobile
operations if they are proposed and we obtain a record in support''
thereof. It declined to authorize mobile operations ``for now,'' not
because of concerns about coexistence with FSS (which it had already
designated as secondary due to the infeasibility of sharing at that
time), but because it was unclear that the technology existed to
facilitate mobile operations and whether mobile operations could share
with fixed operations. The actions, the Commission is taking, are
precisely the actions the Commission contemplated when it established
service rules for LMDS--adding mobile rights to existing LMDS licenses.
32. The Commission also notes that if the Commission had intended
to make mobile operations secondary to FSS, it could have very clearly
done so by explicitly stating that FSS had priority over the mobile
allocation. In the LMDS First Report and Order, when the Commission
intended to discuss the mobile allocation, it specifically referred to
the mobile allocation. If the Commission intended to make mobile
secondary to FSS, it could have specifically referred to mobile instead
of a ``third service.'' Indeed, when the Commission talked of mobile
services in the 28 GHz band, it said that authorizing such services
``would be consistent with the Commission's goal of providing LMDS
licensees with maximum flexibility in designing their systems.'' If the
Commission intended to treat mobile services independently of LMDS, it
would not have referred to providing flexibility to LMDS licensees.
33. FSS operators received multiple notices of their secondary
status. Indeed, in the LMDS First Report and

[[Page 79900]]

Order, the Commission specifically rejected a request from GE Americom
to provide some protection to FSS gateways as ``inconsistent with the
designation of FSS for secondary licensing priority in the 27.5-28.35
GHz band.'' As ViaSat recognizes, FSS license conditions in the 28 GHz
band explicitly state that FSS operations in the 28 GHz band are on an
``unprotected, non-harmful interference basis relative to LMDS.'' The
NPRM in this proceeding noted, ``Twenty stations are licensed for
Earth-to-space transmissions on a secondary basis in the 28 GHz band. .
. .'' That much being said, the Commission recognizes that FSS
operators use the 28 GHz band to provide services and intend to provide
additional services in the future.
34. However, the record in this proceeding does not demonstrate
that the rules that the Commission adopted would significantly risk
harmful interference to satellite operations because of aggregate
interference received at the satellite receiver. Under the existing
rules, LMDS stations have a maximum authorized transmit power of 55 dBW
(85 dBm), versus the 75 dBm the Commission adopted. Furthermore, LMDS
can operate in either point-to-point or point-to-multipoint mode, and
there are no existing limits on upward emissions. In contrast, the
Commission adopted lower power limits for base-station and mobile
operations in UMFUS. Furthermore, the systems contemplated for these
bands have several characteristics that will tend to limit
transmissions towards satellite receivers. As noted in the NPRM, most
industry evaluations of potential mmW mobile base station deployments
appear to assume that such stations' antennas will be tilted downward
at a slight angle, typically from a street lamp pole or a location on a
building at a similar height. Intel explains that this configuration is
necessary not only to direct transmissions toward user equipment but
also to limit interference between adjacent cellular base stations. In
fact, says Intel, failure to adopt this downtilt configuration would
impair throughput to users at cell edges by about 60 percent. Although
ViaSat expresses concern that in some limited locations mobile base
stations might be directed skyward to provide coverage to users in the
upper floors of tall buildings, because of this need for downward
coverage such mobile providers can rely on wired in-building facilities
where necessary. Mobile base stations in this band will probably use
antenna systems that employ dynamic beamforming techniques to produce
beams as narrow as 1.0 degree, which will substantially reduce the
likelihood that such beams will point directly at satellite receivers.
User equipment will also employ antenna arrays to generate dynamic
beamforming, varying both azimuth and elevation in order to maintain
signal connections with their base stations. Again, terrestrial
operators are likely to deploy this technology of their own accord: By
Intel's analysis, choosing not to use dynamic beamforming technology
would reduce throughput at cell edges by about 70 percent. Base
stations and user equipment will also likely employ dynamic power
control, both to avoid draining batteries and to limit intersystem
interference. In fact, both base stations and user equipment could be
entirely silent much of the time; terrestrial operators report that, in
current deployments, network loading rarely exceeds 30 percent. All of
these features will limit the extent of skyward transmissions from
terrestrial mobile systems.
35. In addition, it is important to recognize that most mmW
transmissions will likely not occur in environments that have line of
sight to satellites. By some estimates, as much as 80 percent of
smartphone use occurs indoors, with much of the remainder occurring in
vehicles. Because mmW signals are heavily attenuated by exterior walls,
roofs and windows, signals originating from handheld smartphones will
be largely confined within any buildings or vehicles where they are
used, and would need to be relayed to mobile base stations by other
devices with exterior antennas that will likely have sufficient
beamforming ability to limit skyward transmissions. In principle,
spilling signal power uselessly into outer space would represent a
source of inefficiency, so it is likely that dynamically beamformed
signals will be aimed at receivers on the ground or not far above it.
The most vulnerable satellites--those situated at elevations close to
the horizon--will be protected further by the path losses that
terrestrial signals will encounter in the cluttered environments of
street canyons, suburban foliage, and other obstacles.
36. The Commission has reviewed the studies submitted by the
various parties, including the satellite operators. As discussed in the
Technical Rules section, infra, the Commission concludes that the
various studies submitted by the parties do not support establishment
of an aggregate interference limit. From the satellite operators'
perspective, part of the challenge is that mmW mobile is a new, rapidly
evolving technology, and the terrestrial mobile industry is still
developing system designs and propagation models. Even so, there has
been substantial progress in that regard, and the interference models
submitted by satellite operators in this proceeding do not take into
account prospective features of mmW mobile systems that are readily
accessible on the public record. O3b, for example, assumes that mmW
mobile user equipment will employ no beamforming at all, and will
generate omnidirectional signals. Interference models submitted by
other parties do not adequately account for, and in some cases do not
take into account at all, antenna beamwidths, downtilts, beamforming,
power control, traffic patterns, number of simultaneously transmitting
stations, the obstruction losses that terrestrial signals are likely to
encounter before reaching satellites at low elevations, and the fact
that the majority of transmissions will occur indoors. Terrestrial
operators have every incentive to design networks that direct the
signals they are transmitting to the locations of the receivers--either
another fixed point on a vertical structure, or a mobile unit within a
couple of meters of the ground--especially given the propagation
characteristics of these frequencies. Furthermore, mobile units, which
are likely to be transmitting at angles more skyward, are operating at
powers significantly lower than base stations. These are both true
regardless of the types of systems that are ultimately deployed in
these bands. Nonetheless, given the wide variety of deployments and
uses the Commission expects to see in these bands, it would be
inappropriate to universally mandate these design features in every
deployment, in the absence of more credible support for the proposition
that satellite systems will receive harmful interference from mmW
mobile systems.
37. The Commission's decision not to set specific limits on
aggregate interference is consistent with the Commission's treatment of
that issue in other bands. In AWS-3, the Commission declined to
establish aggregate power limits to protect Federal satellites in the
1761-1780 MHz band because it was unlikely that aggregate interference
was likely to occur. Similarly, in the 10.7-11.7 GHz band, which is
shared between FSS and Fixed Service (FS), the Commission held with
respect to concerns regarding a different type of aggregate
interference: ``[W]e view rule changes that would allow greater FS use
of the 11 GHz band as beneficial to the

[[Page 79901]]

public interest, so long as existing users would not be harmed.''
Similarly, the Commission sees great public benefit to more intensive
terrestrial use of the 28 GHz band where terrestrial use is the primary
designated service in the band.
38. The Commission has concluded that the satellite industry has
not shown that it has a legal right to protection from aggregate
interference or that harmful aggregate interference is likely to occur
from the mobile operations now being authorized for LMDS. The
Commission also recognizes that SES, EchoStar, and ViaSat believe that
satellite and mobile operations can coexist. Nonetheless, the
Commission is sensitive to the concerns raised. The Commission notes
that the satellite and wireless industries have begun the process of
modeling the terrestrial systems under consideration for this band to
provide further information concerning their potential impact on
satellites. The Commission encourages both industries to continue
working cooperatively on this issue, including by submitting any
relevant data demonstrating changes in the amount of aggregate
interference on record as UMFUS services are deployed. The Commission
directs the International Bureau (IB), the Office of Engineering and
Technology (OET), and the Wireless Telecommunications Bureau (WTB) to
jointly establish a separate docket that parties can use to file the
relevant data and analyses, and the Commission reserves the right to
revisit this issue should additional information or other circumstances
warrant further Commission review or action.\2\
---------------------------------------------------------------------------

\2\ In the NPRM, the Commission also sought comment on the
possibility of repealing the prohibition on FSS user equipment in
the 28 GHz band. While there has been considerable comment on this
issue, in light of the evolving nature of technology and deployment
in the band, the Commission does not believe the issue is ripe for
action at this time. Accordingly, the Commission will consider this
issue in the future, either in this proceeding or in a separate
proceeding.
---------------------------------------------------------------------------

5. Band Plan
39. The Commission will license the 28 GHz band as two 425
megahertz blocks. The Commission believes 425 megahertz channels will
be sufficient for a licensee to provide the type of high data rate
services and other innovative uses and applications contemplated for
this spectrum. The fact that several carriers support dividing the
bands into multiple blocks supports that conclusion. The Commission
also agrees with T-Mobile that there are benefits to competition in
allowing multiple licensees to provide service in the 28 GHz band.
40. The Commission emphasizes that existing LMDS Channel A1
licensees will receive licenses for both channels, so they will
maintain their existing license rights. To the extent licensees are
interested in having a contiguous block of 850 megahertz of spectrum,
they are free to acquire both licenses, subject to compliance with the
Commission's spectrum aggregation policies.

B. 39 GHz Band (38.6-40 GHz)

41. In the NPRM, the Commission proposed to develop service rules
for mobile operations in the 38.6-40 GHz band (the ``39 GHz Band'').
This band is currently allocated to the fixed, fixed satellite (space-
to-Earth), and mobile services on a primary basis for non-Federal use.
There are Federal FSS (space-to-earth) and Mobile Satellite Service
(MSS) (space-to-Earth) allocations in the 39.5-40 GHz band, limited to
military systems.
42. The 39 GHz band is licensed by EA and consists of 14 blocks of
50 by 50 megahertz channels. Out of the 2,464 possible terrestrial
fixed service EA licenses available in this band (14 channel pairs for
each of 176 EAs) only 870 licenses currently exist. Other licenses were
voluntarily cancelled or terminated for failure to meet substantial
service requirements. In addition, there are currently 229 active
Rectangular Service Area (RSA) licenses that predate the creation of
the EA licenses in which the licensees self-defined their service area,
and where they retain the exclusive right to operate. The populations
in licensed areas (both EA and RSA licenses) vary by channel, but in
aggregate they cover about 49 percent of the U.S. population. The
Commission has previously indicated that licensees of the band could
have the flexibility to provide mobile service and stated the belief
that ``the issue of technical compatibility of fixed and mobile
operations within a service area is one that can and should be resolved
by the licensee.'' The Commission declined, however, to permit mobile
operations until it conducted a separate proceeding to resolve any
inter-service and inter-licensee interference issues. As a result, no
mobile operations currently exist in the 39 GHz band. To accommodate
high-density fixed terrestrial systems under a ``soft segmentation''
band plan, the Commission has established lower PFD limits for
satellite transmissions in the 37.5-40 GHz band than in other satellite
bands. The Commission notes that there are no commercial satellite
operations in the band.
1. Suitability for Mobile Service
43. The Commission will authorize mobile operation in the 39 GHz
band (38.6-40 GHz), and the Commission will issue new licenses granting
existing and new 39 GHz licensees both fixed and mobile rights. The
Commission believes that the significant bandwidth available in this
band will help to accommodate the expected continued rise in demand for
mobile data. Commenters, including incumbent terrestrial licensees,
overwhelmingly support opening the band for mobile use and expanding
their reach to mobile. The Commission agrees and believes the band can
be used by both mobile and satellite because satellite use can be
accommodated with minimal impact on terrestrial service. The Commission
created the service rules to enable such mobile use, and the Commission
detailed the means by which satellite must cooperate with new mobile
services in these bands to reduce interference and improve service.
2. Licensing the 39 GHz Band
a. Use of Geographic Area Licensing
44. The Commission adopted geographic area licenses that will grant
licensees the flexibility to provide fixed and mobile services. As with
the 28 GHz band, the Commission finds that in this band, geographic
area licensing will expedite deployment, provide licensees with the
flexibility to provide a variety of services, and is consistent with
the existing licensing scheme in the band. The Commission will maintain
the current co-primary Federal FSS and MSS allocations and associated
regulations in this band. The Commission also finds that the presence
of incumbent geographic area licenses in a large part of the country
renders the 39 GHz band a poor candidate for implementing an SAS-based
sharing model.
b. License Area Size
45. The Commission will license the 39 GHz band using PEAs, because
the Commission finds that use of this license area size will facilitate
access to spectrum and the rapid deployment of service in the band.
PEAs are smaller than BTAs or EAs, and therefore are more realistically
obtainable by smaller bidders, yet are larger than counties which
various commenters deem too small. Licensing the 39 GHz band on a PEA
basis strikes the appropriate balance between facilitating access to
spectrum by both large and small providers and simplifying frequency
coordination while incentivizing investment in, and rapid deployment
of, new technologies. PEAs also nest into

[[Page 79902]]

EAs but can also be broken down into counties, allowing operators to
combine or partition their PEAs into the license areas of their choice.
The Commission believes that the size and ability to combine/partition
will aid in the rapid deployment of these licenses. The Commission's
decision to license the 39 GHz band on a PEA basis is distinguishable
from the Commission's decision to use counties as the license area in
the 28 GHz band, because, as previously discussed, the latter band is
currently licensed by BTAs and cannot readily be reformed into either
EAs or PEAs.
3. Mobile Rights for Incumbents
46. The Commission adopted its proposal to grant mobile operating
rights to existing active 39 GHz licensees for the same reasons the
Commission granted mobile operating rights to LMDS incumbent licensees.
Granting mobile operating rights to existing licensees will expedite
the deployment of service, minimize the difficulties involved in
coordinating fixed and mobile deployments, and provide a uniform
licensing scheme throughout the United States. In contrast, separating
fixed and mobile rights through assignment of overlay licenses would
delay the implementation of mobile service. The Commission remains
concerned that awarding fixed and mobile rights separately would lead
to disputes between fixed and mobile licensees that could make it more
difficult for both licensees to provide service.
47. The Commission recognizes that awarding mobile rights to
incumbent licensees could be viewed as a windfall to those licensees,
although the Commission contemplated granting mobile rights when it
first created LMDS. Here, the benefits of expediting service and
facilitating the coordination of fixed and mobile service outweigh any
potential disadvantages of granting mobile rights to incumbents.
4. Non-Federal Satellite Terrestrial Sharing--Licensing of Gateway
Earth Stations
48. The NPRM invited comments on three issues relating to FSS use
of the radiofrequency spectrum from 37.5 GHz to 40 GHz, encompassing
both the 38.6-40 GHz (39 GHz) band and the 37-38.6 GHz (37 GHz) band.
The first question was whether the Commission should make any changes
to its treatment of gateway earth station applications; the second,
whether it would be reasonable to eliminate the prohibition against
ubiquitous deployment of user equipment; and the third question,
whether it would be feasible to allow satellite operators to increase
their PFDs above existing limits during heavy rain storms. In none of
those cases did the Commission foresee any reason to differentiate
between the 37 GHz and 39 GHz bands with respect to satellite sharing
issues.
49. The U.S. Table of Frequency Allocations accords co-primary
status to FSS earth stations in the 37.5-40 GHz frequencies, but
Commission rules provide that gateway earth stations in the 39 GHz band
may be deployed only if the FSS licensee obtains a 39 GHz license for
the area where the earth station will be located, or if it enters into
an agreement with the corresponding 39 GHz licensee. The Commission
mentioned the changes that the NPRM was proposing for the licensing of
satellite operations in the 28 GHz band and sought comment on whether
similar changes should be adopted for the 37.5-40 GHz channel groups.
The NPRM asked whether the Commission should establish a waiver process
by which non-Federal FSS earth stations in the 37.5-40 GHz bands could
acquire co-primary status in areas where there is no geographic service
area licensee, if they can demonstrate that doing so would not have a
negative impact on future terrestrial service. The Commission asked if
the fact that 37.5-40 GHz FSS operations are space-to-Earth, rather
than Earth-to-space as in the 28 GHz band, should lead to different
answers to these questions. The Commission also sought comment on any
other changes it should make to the existing rules.
50. Commenters acknowledge that the space-to-Earth nature of
satellite operations in the 37.5-40 GHz bands means that it is earth
stations that need protection against interfering signals from
terrestrial operations rather than the opposite situation that applies
for Earth-to-space operations in the 28 GHz band. EchoStar calculates
that satellite earth stations in the 37.5-40 GHz band will need
exclusion zones with radii extending no more than about two kilometers.
EchoStar states this radius in the 37.5-40 GHz bands is about 12 times
the radius (170 meters) circumscribing the exclusion zone that EchoStar
says is required for earth stations in the 28 GHz band. The areas
required for the resulting exclusion zones would be about 138 times as
large--12.6 square kilometers (4.9 square miles) for the 37.5-40 GHz
bands versus 0.09 square kilometers (0.03 square miles) for the 28 GHz
band. By comparison with the 28 GHz band, therefore, accommodating
satellite earth stations in the 39 GHz band is approximately two orders
of magnitude more difficult.
51. The smallest counties mentioned in the Commission's discussion
of satellite interference zones for the 28 GHz band each cover about 80
square kilometers. The exclusion area that EchoStar says is required
for the 37.5-40 GHz frequencies would cover about 16 percent of such a
county--a proportion that could seriously impair the growth prospects
for mmW mobile. The challenge is less daunting when the Commission
considers the possibility of authorizing earth station sites on a PEA
basis rather than a county basis. The average PEA in the 48 contiguous
U.S. states covers about 18,692 square kilometers (7,217 square miles).
Therefore, the requisite exclusion zone would cover about 0.0674
percent of the average PEA's land mass in the contiguous U.S. If people
were evenly distributed across this hypothetical average PEA,
substantially less than 0.1 percent of its population would fall in the
earth station's exclusion zone.
52. These calculations show that some PEAs should be able to host a
39 GHz earth station without placing more than 0.1 percent of the PEA's
population in the earth station's exclusion zone. Most PEAs cover
substantially less territory than the average PEA does; i.e., even for
some PEAs, a five square-mile exclusion zone might affect an
unacceptably high proportion of their populations. But satellite
operators will not necessarily need to deploy 39 GHz earth stations in
the smaller, more densely populated PEAs. For satellite gateway earth
stations in particular, the sine qua non is not proximity to population
centers, per se, but access to long-haul, high data-rate Internet
facilities. Direct access to long-haul Internet nodes is available not
just in major population centers but also in some of the more remote
parts of the U.S. Many of those nodes are in places with comparatively
low population densities--i.e., near areas where it should be possible
to deploy earth stations without creating exclusion zones that affect
unacceptably high proportions of the population. In addition, as the
Commission suggested for the 28 GHz band, satellite operators can
substantially reduce the sizes of the exclusion zones that they require
by constructing artificial site shields or by taking advantage of
naturally occurring terrain features. Spatial analysis software can
process digital elevation data to identify geographic depressions,
which are capable of providing natural site-shielding in all
directions. For earth stations that communicate only with
geosynchronous satellites, more limited site shielding would typically
suffice. In

[[Page 79903]]

addition, satellite operators may continue to protect their earth
stations from interference using any of four market-oriented
mechanisms: Purchasing geographic area licenses at auction, acquiring
licenses from existing licensees, obtaining partitioned segments of
existing geographic area licenses from existing licensees, or obtaining
contractual agreements from nearby licensees not to interfere into
their earth station operations.
53. Based on those considerations, the Commission will authorize
non-Federal satellite earth stations in the 39 GHz band on a first-
come, first-served basis that will entitle them to protection from
terrestrial transmissions subject to the following conditions.\3\
First, the earth station applicant must define a protection zone in its
application around its earth station where no terrestrial operations
may be located. The FSS applicant may self-define this protection zone,
but it must demonstrate using reasonable engineering methods that the
designated protection zone is no larger than necessary to protect its
earth station. Second, the Commission will authorize a maximum of three
protection zones in each PEA, so the applicant must demonstrate that
there are no more than two existing protection zones in the PEA or
demonstrate that its protection zone will be contiguous to any
preexisting satellite protection zone. Third, the applicant must
demonstrate the existing and proposed protection zones, in the
aggregate, will not cover more than 0.1 percent of the PEA's
population.\4\ Fourth, the applicant must show that the protection zone
does not infringe upon any major event venue, arterial street,
interstate or U.S. highway, urban mass transit route, passenger
railroad, or cruise ship port. Finally, the earth station applicant
must coordinate with terrestrial fixed and mobile licensees whose
license areas overlap with the protection zone, in order to ensure that
the protection zone does not encompass existing terrestrial operations.
The coordination requirements will be based on the Commission's
existing requirements contained in Sec. 101.103(d) of the Commission's
rules. If the earth station is authorized, UMFUS licensees will be
prohibited from placing facilities within the protection zone absent
consent from the FSS operator, and the FSS operator must respond in
good faith to requests to place facilities within a protection zone.
---------------------------------------------------------------------------

\3\ The Commission adopted a new footnote, NG63, to the
Allocation Table that reflects the existing limitation to gateway
earth stations. See 47 CFR 25.202(a)(1) n.3.
\4\ The IB will issue a public notice seeking comment on the
appropriate methodology to calculate the 0.1 percent population
limit and will also seek comment on best practices for earth station
siting to minimize impact on UMFU services, colocation of earth
stations, and accommodating multiple earth station interference
zones without exceeding 0.1 percent of population in a given PEA.
---------------------------------------------------------------------------

5. Band Plan
54. The Commission will create seven 200 megahertz bands out of the
39 GHz band (38.6-40 GHz). The Commission finds that this channel size
is large enough to take advantage of the data throughput capacity of
these bands yet yields a sufficient quantity of channels in the band to
provide access to multiple operators simultaneously. The Commission
agrees with the comment that next generation 5G networks are expected
to depend in part on higher frequencies, increased spectral efficiency
and greater density of cell deployments and that these factors alone
may be insufficient to meet the expected tenfold increases in peak data
rates and user throughput without using ultra-wide channel bandwidths
of at least 200 MHz. These wider channels available at higher
frequencies could allow for higher data rates in environments
constrained by power or signal-to-noise ratios. By facilitating higher
throughput, wideband channels will thereby permit more users to
simultaneously use the band.
55. The Commission also modified the current band plan that is
based on paired spectrum blocks in favor of larger, unpaired channels
to enable Time Division Duplexing (TDD) which commenters believe will
best enable a 5G mobile service environment. Straight Path asserts that
TDD is preferable in these frequencies given the current lack of
adequate frequency duplexers capable of meeting the performance, cost
or form factor requirements necessary to facilitate Frequency Division
Duplexing (FDD) at these higher wavelengths. TDD does not require a
frequency duplexer and allows flexible downlink-uplink ratios that
depend on traffic and result in efficient utilization of spectrum.
While these and other commenters note the benefits of TDD in the
context of 5G, commenters overwhelmingly support rules that allow for
flexible duplexing schemes, and the rules the Commission adopted will
allow any type of duplexing. Licensees may also continue to offer FDD
service by acquiring and pairing multiple spectrum blocks. Because the
existing channel plan favors FDD operation and limits flexibility to
accommodate other duplexing schemes, reconfiguring the channel plan
will remove obstacles to TDD schemes while still allowing for
flexibility to accommodate FDD. Furthermore, larger bandwidths may
optimize traffic management and improve system performance because a
single, wide carrier permits centralized spectrum management whereas
aggregation and use of various narrow bandwidth channels requires
greater power consumption and equipment complexity. Finally, 200
megahertz channels will potentially create several empty channels for
new entrants after incumbent licensees swap or repack their existing
systems into consecutive or adjacent channels. Given all of the
considerations above, the Commission finds that 200 MHz channels are
the best band size for 39 GHz.
6. Pre-Auction License Reconfiguration
56. Straight Path's proposal contains the clearest delineation of
rules and steps necessary to align adjacent spectrum tranches to create
contiguous bands--the goal advocated by commenters. The Commission
agrees with Straight Path that in EAs where only it holds licenses, the
Commission should accept any exchange application in which Straight
Path or others propose to acquire the same amount of spectrum in the
market that it proposes to relinquish as long as it meets the end goal
of creating a contiguous block or blocks of spectrum. In instances
where there are multiple geographic area licensees, Straight Path
advocates that the Commission should first accept any band plan
mutually acceptable to the various licensees as long as it also
increases the amount of contiguous spectrum for at least one of the
licensees. If licensees do not agree on a band plan, Straight Path
argues the Commission should accept applications in which an incumbent
geographic area licensee seeks to acquire any contiguous spectrum
blocks adjacent to spectrum blocks it already holds subject to two
limitations (i) the target spectrum block is not already occupied by
another incumbent geographic area licensee; and (ii) the target
spectrum block could not be requested by another incumbent geographic
area licensee on the grounds that it is adjacent to a block it holds or
that it could hold. A licensee should be able to continue to add
contiguous unused blocks in a row until it reaches a prohibited block--
i.e., a spectrum block that could also be claimed by another incumbent
licensee. Straight Path suggests that in this way, contiguous occupied
bands could be aligned starting at the lower edge of the band--at 38.6
GHz--and moving up toward 40 GHz. Because the Commission adopted a band
plan for the

[[Page 79904]]

37 GHz band that provides for continuity of commercial operations
across the 37 GHz and 39 GHz bands, when the bands are viewed together,
Straight Path's swapping plan results in occupied spectrum in the
middle of the combined bands. One alternative might be to push
incumbents to the upper end of the band near 39.5 GHz, in order to
create larger available swathes of spectrum by combining the lower
frequencies with the open bands in the 37 GHz band. However, in the
interest of addressing mobile data demand as quickly as possible, 39
GHz licensees at the bottom of the band will provide the first market
for mmW mobile equipment as soon as it becomes available, and this will
further the goal of interoperability by allowing fixed licensees to
more rapidly foster the development of mobile in their bands.
57. Some of the 200 MHz spectrum blocks offered at auction will
also contain at least one incumbent RSA licensee occupying some portion
of the spectrum. Straight Path argues that where the incumbent
geographic license holder is also the RSA licensee, the RSA license
will be deemed not to exist and will be cancelled upon an exchange.
Otherwise, incumbent licensees will only be permitted to elect to add
contiguous channels with greater encumbrances than vice versa;
accordingly, a geographic area licensee can always opt to exchange a
block without an RSA for an adjacent block with an RSA whose operations
it will have to protect, and similarly it can always opt to take a
license area with a more encumbered RSA over a block it holds with a
less encumbered RSA, but it cannot ``upgrade'' to an RSA-free block or
a license with an embedded RSA that is less encumbered. Overall,
although Intel and Straight Path have argued that EAs are the
appropriate geographic area for new licenses given their historical use
and the complexity of the swap process, as discussed above, the
Commission's preferred license area size for the 39 GHz band are PEAs,
and such PEAs neatly fit into the EAs they comprise. Accordingly, once
incumbents' spectrum swapping has run its course at the EA level, the
resulting license area/band combinations should be further broken down
into PEAs, which `nest' into EAs.
58. The Commission believes this reconfiguration process will yield
a band, and licenses, that are more useable by incumbents as well as
new entrants for the new flexible use services, including mobile
broadband that the Commission is authorizing in this Report and Order.
Straight Path currently holds 931 licenses out of 1,098. If Straight
Path voluntarily reconfigures its rights as it has advocated, this will
substantially reduce encumbrances (i.e., remaining RSAs or blocks
within EAs that have not been reconfigured) that might exist in new
license areas before a future auction. While the Commission adopted a
voluntary reconfiguration approach, it is its hope and expectation that
all licensees will take advantage of this opportunity to convert their
licenses to the new flexible use licensing scheme and band plan.
Furthermore, while the Commission adopted a voluntary approach, the
Commission notes that under Section 316 of the Act the Commission
retains the right to modify any license consistent with the public
interest.

C. 37 GHz Band (37-38.6 GHz)

59. The 37 GHz band presents a number of opportunities because,
other than a limited number of existing Federal uses that need
protection, the band is a greenfield--there are no existing non-federal
operations, terrestrial or mobile. In addition, it is adjacent to the
39 GHz band, which presents an opportunity to create a larger,
contiguous 37/39 GHz band, subject to similar technical and operational
rules. Also, the Federal fixed and mobile service allocations are
lightly used. The approach the Commission adopted takes full advantage
of these opportunities.
60. Specifically, the Commission can meet the twin goals of
expanding commercial access in this band while facilitating continued
and expanded Federal use. Because there are both Federal and non-
Federal fixed and mobile rights and there are minimal incumbency issues
(or an installed base of equipment), the approach the Commission
adopted in this band can significantly further the regulatory, policy,
and technical approaches to Federal and non-Federal sharing. As
discussed in greater detail below, the Commission adopted a band plan
that allows for continuity of commercial operations between the 37 and
39 GHz bands, the Commission protects a limited number of Federal
military sites across the full 37 GHz band, and the Commission
identifies 600 megahertz of spectrum that will be available for
coordinated coequal shared access between Federal and non-Federal
users. Through this structure, additional proposals in the Further
Notice of Proposed Rulemaking (FNPRM), and the collaborative industry/
government process that will take place to further define the sharing
process and paradigm, the Commission will take substantial strides
forward on Federal and non-Federal sharing in the mmW bands while also
making a significant amount of spectrum available for wireless
broadband.
1. Suitability for Mobile Use
61. The Commission adopted rules to permit fixed and mobile
terrestrial operation in the 37 GHz band to enable as wide a range of
services as possible. The Commission finds that there are several
important characteristics of the 37 GHz band that make the provision of
fixed and mobile terrestrial operations especially promising: It
contains 1.6 gigahertz of contiguous spectrum, which could support
ultra-high data rates; it is contiguous with the 39 GHz band, which
will permit operators to aggregate spectrum across both bands; and it
has global co-primary fixed and mobile allocations, which could enable
operators to achieve economies of scale. Cisco urges us to proceed
cautiously, and Boeing urges the Commission to wait until the studies
called for by the WRC-15 are completed, the Commission is persuaded
that fixed and mobile terrestrial services can be provided in the 37
GHz band. In this regard, in analyzing the suitability of the 37 GHz
band for mobile service, the band is very similar to the 39 GHz band.
It has an existing mobile allocation, the propagation characteristics
are very similar to the 39 GHz band, and the Commission does not see
any inconsistency with other allocations that would make the band
unsuitable for mobile service. In terms of timing of the Commission's
action, considering the potential benefit for 5G services and the
significant lead time that will be necessary to develop the services in
this band, the Commission believes that the Commission should move
forward and develop fixed and mobile terrestrial services rules for the
37 GHz band. Moreover, as discussed more fully below, the rules the
Commission adopted accommodate the needs of National Aeronautics and
Space Administration (NASA), National Science Foundation (NSF), the
military, and FSS operations in the 37 GHz band as well as Earth
Exploration Satellite Service (EESS) (passive) and Space Research
Service (SRS) (passive) operations in the adjacent 36-37 GHz band.
2. Licensing the 37 GHz Band
62. The Commission adopted a licensing approach that makes five 200
megahertz blocks available on a geographic area-licensed basis in the
37.6-38.6 GHz portion of the band (upper band segment). The Commission

[[Page 79905]]

will make the 37-37.6 GHz block (lower band segment) available for
coordinated co-primary sharing between Federal and non-Federal users,
where non-Federal rights are granted by rule. The Commission notes that
the entire band is subject to Federal co-primary fixed and mobile
allocations. The Commission declines to adopt the hybrid authorization
licensing scheme because it is unsupported by the record. Specifically,
commenters oppose it because they do not believe that the 37 GHz band
is appropriate for this particular scheme, though it could be used for
other bands. In addition, the satellite industry expresses concern that
the hybrid licensing approach does not provide satellite operators with
any meaningful certainty that they will be able to expand into the 37
GHz band.
63. Of the three licensing options that the Commission sought
comment on in the NPRM, the Commission finds that a variation of the
Commission's alternative proposal best enables the band to be used for
new commercial uses while simultaneously allowing fixed and mobile
Federal use to expand. Although there is support in the record to
license the entire 37 GHz band by geographic area, the Commission finds
that it is in the public interest to license a portion of this band on
a non-exclusive shared basis, and to license the remainder of the band
by geographic area to give potential licensees additional opportunity
to access large blocks of spectrum or to use 37 GHz spectrum in
combination with, and similarly to, 39 GHz spectrum. Allowing part of
the band to be made available on a non-exclusive, shared basis will
promote access to spectrum by a wide variety of entities, support
innovative uses of the band, and help ensure that spectrum is widely
utilized. Adopting geographic area licensing for the other portion of
the band will expeditiously make spectrum available and allow common
development of the 37 GHz and 39 GHz bands. Furthermore, users in the
shared portion of the band will benefit from efforts by equipment
manufacturers and licensees to develop equipment for the portion of the
band licensed on a geographic area basis. Thus, the Commission finds
that adopting the alternative proposal, as modified below, should
promote investment and deployment in both bands. As explained below,
the Commission agrees that there are benefits to adopting the same
geographic area licensing framework for the 37 GHz and 39 GHz spectrum
bands. Also, the Commission finds that adopting the alternative
proposal, in addition to other decisions made by the Commission,
provides satellite operators the certainty they need to be able to
expand their operations into the 37 GHz band in the future.
64. The Commission adopted a modified version of the alternative
proposal as follows: The Commission will create a band plan with a 600
megahertz shared block in 37-37.6 GHz and a geographically-licensed
portion in 37.6-38.6 GHz. The lower band segment will be fully
available for use by both Federal and non-Federal users on a
coordinated co-equal basis. Non-Federal users, which the Commission
will identify as Shared Access License (SAL), will be authorized by
rule. Federal and non-Federal users will access the band through a
coordination mechanism, including exploration of potential dynamic
sharing through technology in the lower 600 megahertz, which the
Commission will more fully develop through the FNPRM and through
government/industry collaboration. The Commission envisions this
segment serving as a proving ground for Federal and non-Federal sharing
in the mmW bands, as a way to facilitate expanded Federal use in the
band, an opportunity to facilitate lower-cost access to mmW bands, and
a means for all providers to gain additional capacity where and when it
is needed.
65. As described below, the Commission adopted the same technical
rules for the shared band segment as the Commission does for the rest
of the 37 GHz band. These technical rules are also consistent with the
39 GHz band. The Commission also adopted an operability requirement
that will ensure equipment developed for the 37 and 39 GHz bands is
able to operate across the entire 37-40 GHz band. This will help drive
scale in the development and access to the equipment, and allow users
in the shared portion of the band, including Federal users, to benefit.
In order to ensure a sharing environment in 37-37.6 GHz that is
predictable, manageable, and efficient, the Commission strongly
encourages Federal users to comply with the same technical rules, and
will work with National Telecommunications and Information
Administration (NTIA) to explore establishment of guidance in its
regulations.
66. Following the adoption of this Report and Order, the WTB and
OET will, in collaboration with NTIA and Federal stakeholders, work
with industry stakeholders and other interested parties to further
define the sharing framework. The Commission will hold one or more
public meetings to examine the state of innovative sharing techniques
and technologies and to have an open dialogue about how sharing can
best be implemented and achieved in the 37-37.6 GHz band. The
Commission strongly encourages both industry and Federal stakeholders
to use new and existing experimental testbeds to develop sharing
approaches and technologies. Based on stakeholder feedback, the WTB and
OET may, jointly with NTIA, issue a public notice seeking comment on a
refined and detailed 37 GHz sharing framework. In response to the
record developed, the Commission, jointly with NTIA, will establish the
37 GHz sharing mechanism. The Commission believes this inclusive and
collaborative process ensures that all parties' needs are met and that
an effective and robust sharing mechanism will be developed.
67. In the upper band segment (37.6-38.6 GHz), the Commission will
use geographic area licensing with PEAs as the licensing unit, which is
consistent with the licenses in the 39 GHz band. In this band, there
will be Federal co-primary use coordination zones around 14 military
sites where the military will have the right to operate fixed and
mobile operations, and the three SRS sites as described below. Non-
Federal users will be able to access these locations through a
coordination mechanism that will be developed and established by WTB
and OET in conjunction with NTIA and announced via Public Notice. The
Commission also recognizes that there are existing Federal and non-
Federal fixed and mobile allocations in the upper band segment, and in
the FNPRM, the Commission seeks comment on developing additional
criteria under which Federal users can obtain access to the upper band
segment.
68. The Commission believes licensing the 37 GHz band in this
manner has many benefits. In the lower band segment, the Commission is
creating an innovative shared space that can be used by a wide variety
of Federal and non-Federal users. SALs will be widely available to
provide easy access to spectrum, including for new innovative uses and
for targeted access where and when providers need additional capacity.
It will help further efforts to facilitate sharing between Federal and
non-Federal users, and will give Federal users and consumers an
opportunity to take advantage of speed-to-market and lower cost of
broadly deployed commercial technologies, and provide Federal users
opportunities for current use and future growth. In the upper band
segment, the Commission notes that the 37 GHz band and the 39

[[Page 79906]]

GHz band will be licensed under the same framework, with identical
technical and licensing rules. They will both be licensed by PEAs,
which will allow licensees in the 37 GHz and 39 GHz bands to aggregate
blocks of spectrum or to pair blocks of spectrum.
69. Below, the Commission discusses in further detail some of the
decisions the Commission has made concerning the 37 GHz band. In the
FNPRM, the Commission seeks comment on refining the sharing framework
the Commission adopted.
3. License Area Size
70. The Commission is presented with a unique opportunity to adopt
a licensing scheme that will apply to 2,400 megahertz of contiguous
spectrum, the upper segment from 37.6-38.6 GHz together with the 38.6-
40 GHz band. In the shared band segment, the Commission will authorize
fixed and mobile users on a site-based coordinated basis. The
Commission believes this approach will allow users to access spectrum
where and when it is needed, which will help maximize spectrum by
providing opportunities for each user to target just the areas it
needs. The Commission is licensing the 39 GHz band by PEA. The
Commission's reasons for adopting PEAs as the geographic area for the
39 GHz band apply here as well. Specifically, as the Commission noted
with respect to the 39 GHz band, after reviewing the record, the
Commission now believes that PEAs strike the appropriate balance
between facilitating access to spectrum by both large and small
providers and simplifying frequency coordination while incentivizing
investment in, and rapid deployment of, new technologies. Thus, the
Commission adopts the same geographic license structure for both the
upper band segment of the 37 GHz band and the 39 GHz band. This
decision will give licensees the flexibility that they need and will
encourage investment in a wide variety of services and technologies.
4. Band Plan for Upper Band Segment
71. The Commission will divide the upper band segment into five
blocks of 200 megahertz each for non-Federal users. As explained in
this Report and Order, the Commission is attempting to create a
consistent and coherent licensing framework that can be applied
throughout the mmW bands, with modifications based on the
characteristics of a particular band. The Commission's decision to
choose 200 megahertz channels rather than 533 megahertz channels also
stems, in part, from the Commission's previous decision to create two
licensing segments for the 37 GHz band: A 600 megahertz lower band
segment licensed by rule, and a 1,000 megahertz upper segment, which
will be licensed geographically by PEA. Adopting 200 megahertz channel
sizes for the upper band segment is consistent with the 200 megahertz
channels the Commission adopted for the 39 GHz band. Because the
Commission licenses the upper band segment of the 37 GHz band and the
39 GHz band by PEA, licensees will have the flexibility to pair their
37 GHz license with a 39 GHz license.
72. In addition, the provision of fixed and mobile terrestrial
operations at this frequency will depend upon large blocks of spectrum
and a single 200 megahertz block provides a sufficient amount of
spectrum for the provision of high-capacity wireless broadband. Those
licensees needing more spectrum than a 200 megahertz channel can
combine channels to create contiguous blocks of 200 megahertz channels,
either within the 37 GHz band or by combining 37 GHz spectrum with 39
GHz spectrum. Licensees also have the option of acquiring 425 megahertz
channels in the 28 GHz band.

D. 64-71 GHz Band

73. The Commission is making available the 64-71 GHz frequency band
for use by unlicensed devices pursuant to the same technical standards
as in the 57-64 GHz frequency band under Sec. 15.255 of the
Commission's rules, with slight modifications. As the Commission has
consistently stated, it is optimal to include a balance of licensed
rights and opportunities to operate on an unlicensed basis in order to
meet the country's wireless broadband needs. The Commission's action
here creates a 14-gigahertz segment of contiguous spectrum in these
frequency bands to encourage the development of new and innovative
unlicensed applications, and promote next-generation high-speed
wireless links with higher connectivity and throughput, while
alleviating spectrum congestion from carrier networks by enabling
mobile data off-loading through Wi-Fi and other unlicensed connections.
74. The Commission is adopting rules to allow for unlicensed
operations in the 64-71 GHz band, subject to the technical standards in
Sec. 15.255, thus creating a contiguous spectrum segment with the 57-
64 GHz band. The Commission observes that unlicensed WiGig devices
using the 57-64 GHz band are just beginning to be marketed and these
products are standardized pursuant to an internationally harmonized
channelization scheme, which should promote their growth and usage.
Making available additional spectrum contiguous to the existing 57-64
GHz band may enable higher throughputs and enhanced use of present
spectrum, as well as to permit an increase in the number of
simultaneous high-bandwidth users. The Commission agrees with Intel
that a lesser amount of spectrum would limit the growth potential of 60
GHz applications. The Commission also agrees with the WISPA that
``because ITU may study a band is an insufficient reason for the
Commission to delay making a valuable spectrum resource available for
unlicensed use.'' The Commission acknowledges that eventual
harmonization with international requirements will benefit consumers by
promoting a global marketplace and enhancing the international
competitiveness of U.S. manufacturers. However, notwithstanding a
desire for harmonization with international standards, the Commission
determines to make these frequencies available for unlicensed use based
on the Commission's analysis of U.S.-specific factors. Here, the
Commission determines that the Commission should not wait for the
outcome of the ITU study of this band, contrary to what T-Mobile
advocates, because that could take years, leaving 5 gigahertz of
spectrum to lie fallow in the meantime, when unlicensed applications
are ready in the very near future to make use of this spectrum, given
current planned deployments of WiGig products in the adjacent 57-64 GHz
band.\5\ In addition, note that spectrum characteristics vary at
different frequencies, due to different propagation losses and other
atmospheric and sharing conditions, thus a strict linear comparison per
frequency unit of the Commission amounts in different frequency bands
as ``gigahertz parity'' (e.g., 3.85 gigahertz of spectrum in lower
bands vs. 14 gigahertz of spectrum in upper bands) is not a valid
comparison. Based on the above, the Commission is permitting use of the
57-71 GHz band by unlicensed devices pursuant to the technical rules in
Sec. 15.255.
---------------------------------------------------------------------------

\5\ The Commission also notes that the ``study'' of a frequency
band by the ITU does not mean necessarily that the band will be
automatically designated for licensed use, because licensing of
spectrum is deferred to ``the sovereign right of each State to
regulate its telecommunication''. See International
Telecommunication Union, Constitution and Convention (http://www.itu.int/en/history/Pages/ConstitutionAndConvention.aspx).
---------------------------------------------------------------------------

75. With respect to the additional requests from Microsoft et al to
extend

[[Page 79907]]

the band up to 72.5 GHz, and to allow indoor use of the 72.5-76 GHz
band by unlicensed devices, the Commission does not find that
additional spectrum above and beyond the very large 14-gigahertz of
contiguous spectrum in the 57-71 GHz band that the Commission is
providing for unlicensed operations herein is warranted at this time,
due to the presence of the numerous existing fixed links in the 71-76/
81-86 GHz bands. When the Commission adopted rules for licensed
operations in these bands in 2003, it did not permit unlicensed sharing
of these bands because ``an underlay of unlicensed devices in the bands
could detrimentally affect the quality and buildout of service.'' In
addition, the fixed point-to-point equipment that has been developed
for deployment in the 71-76 GHz and 81-86 GHz bands were not engineered
to operate in a part 15 unlicensed environment. Subsequently, in 2014,
the Commission adopted part 15 rules to permit a special type of
unlicensed device, level probing radars (LPR), to share the 75-85 GHz
band; these devices, however, must be operated in a vertically downward
position at fixed locations with severe limitations on antenna
beamwidth. In contrast, the 5G unlicensed transmitters envisioned here
would be both mobile and fixed and would not have such limitations. The
Commission finds that parties requesting to extend the band beyond 71
GHz for unlicensed operation did not submit any persuasive technical
arguments to prove that unlicensed sharing with the 71-76/81-86 GHz
licensed services is feasible at this time. Accordingly, the Commission
denies these requests at this time.

E. Federal Sharing Issues

76. Many bands above 24 GHz have Federal allocations on a primary
basis. As the Commission continues to increase flexibility in the non-
Federal use of these bands, the Commission must consider appropriate
mechanisms and tools to share these bands that recognize the co-primary
rights in these bands. In this Report and Order, the Commission
facilitates sharing in the 39.5-40 GHz band and 37-38.6 GHz band,
including through new sharing schemes that promote dynamic and flexible
access in the 37-37.6 GHz band. In order to continue to evolve spectrum
access and sharing regimes that meet both Federal and non-Federal
needs, it will be imperative for all stakeholders, including wireless
and satellite industries, to engage proactively to help shape these
solutions.
1. 39.5-40 GHz
77. The 39.5-40 GHz portion of the 39 GHz band is allocated to the
Federal FSS and MSS a primary basis, limited to space-to-Earth
(downlink) operations. However, Federal MSS earth stations in this band
may not claim protection from non-Federal fixed and mobile stations in
this band.
78. In the NPRM, the Commission explained that when the 39 GHz
Report and Order was adopted, Federal use of the band was limited to
military systems in the 39.5-40 GHz band segment, that the Department
of Defense (DoD) stated that it had plans to implement satellite
downlinks at 39.5-40 GHz in the future, and that the NASA identified
39.5-40 GHz as a possible space research band to accommodate future
Earth-to-space wideband data requirements. The 39 GHz Report and Order
expressed optimism that such plans would not affect the continued
development of the 39 GHz band for non-Federal use, but the Commission
said that it intended to address those interference issues in a future,
separate proceeding that would focus on developing inter-licensee and
inter-service standards and criteria. At present, the U.S. Table of
Frequency Allocations provides that Federal satellite services in the
39.5-40 GHz band are limited to military systems.
79. Although only four commenters responded to the Commission's
questions on these issues, all four agreed that it is possible for
Federal and non-Federal operations to share the 39 GHz band. They also
agreed that the Commission should adopt coordination zones to mitigate
interference between Federal and non-Federal operations. For instance,
AT&T argues that the Commission should adopt coordination zones rather
than novel spectrum sharing techniques because coordination zones
balance the twin goals of efficient spectrum utilization and the
prevention of harmful interference to incumbents. Intel argues that
portions of the band that are strictly Federal use could be separated
from those for commercial use. Cisco states that while coordination
will have to be done by the Commission staff and their counterparts at
NTIA, co-existence is achievable. Finally, Nokia argues that the
Commission should continue work with NTIA and other Federal agencies to
minimize Federal coordination zones, which would maximize the value of
the spectrum.
80. In 2016, NTIA sent a letter to the Commission addressing issues
raised in the NPRM, regarding, in part, military operations in the
39.5-40 GHz portion of the 38.6-40 GHz band. NTIA explained that the
39.5-40 GHz band is allocated to military MSS and FSS earth stations.
Federal MSS earth stations cannot claim protection from non-Federal
fixed and mobile stations as specified in footnote US382 of the table
of frequency allocations. However, Federal earth stations in the MSS
are not required to protect non-Federal fixed and mobile services. NTIA
stated that given the existing regulatory constraints in the 39.5-40
GHz band, the NPRM's proposed non-Federal fixed and mobile operations
will not impact Federal satellite operations in the 39.5-40 GHz band.
81. The Commission concludes that it is possible for Federal
operations to share the band with non-Federal fixed and mobile
terrestrial operations because the protections offered by footnote
US382 are sufficient to protect both Federal and non-Federal operations
in this band. Thus, no changes to the Commission's rules are necessary.
2. 37-38.6 GHz
82. The Commission concludes that non-Federal fixed and mobile
operations can share the 37-38 GHz band with SRS downlink operations
under certain conditions. First, as a result of discussions between
NTIA and the Commission, NTIA indicated that it would request
protection for only three SRS earth station sites: Goldstone,
California; White Sands, New Mexico; and Socorro, New Mexico. Second,
to address NTIA's recommendations, the Commission will establish
coordination zones for these three sites by adding a footnote to the US
Table of Allocations listing the locations to be protected and their
respective coordination zones. Third, with respect to operations, at
Green Bank, West Virginia, NTIA indicated that since Green Bank, West
Virginia is located in an existing quiet zone, any new or modified
stations including in the fixed and mobile services, within the zone
are required by Sec. 1.924(a) of the Commission's rules to notify the
National Radio Astronomy Observatory (NRAO), and thus Green Bank would
not be included in the footnote. Therefore, the Commission adopted
footnote US151, which requires that, in the 37-38 GHz band, fixed and
mobile stations not cause harmful interference to Federal SRS earth
station at three sites and that non-Federal applications for such use
be coordinated with NTIA in accordance with new Sec. 30.205 of the
Commission's rules.
83. The Commission concludes that non-Federal fixed and mobile
operations can share the 37-38.6 GHz band with DoD operations. With
regard

[[Page 79908]]

to Federal co-primary access to the 37 GHz band, the Commission will
adopt rules that entail the coordination zones recommended by NTIA for
the 14 military sites, and the ability for Federal agencies to add
future sites on a coordinated basis. The Commission will make the 37-
37.6 GHz block (lower band segment) available for coordinated co-
primary sharing between Federal and non-Federal users, where non-
Federal rights are granted by rule. This framework will facilitate
access by DoD and other Federal users. In the FNPRM, the Commission
seeks comment on defining the sharing framework in greater detail. In
the upper band segment, the Commission seeks comment on facilitating
Federal coordination with licensees for access to licensed areas.
84. The Commission also does not believe that it is necessary to
take action to protect the weather satellites, which according to
Committee on Radio Frequency (CORF), will operate above 37 GHz until at
least 2020 because it will take a significant amount of time for mmW
devices to be developed and deployed in the 37 GHz band. Therefore, the
Commission expects that relatively few mmW devices will be operating in
the band while the weather satellites are still in use.
85. Under the plan the Commission adopted, the Commission enables
the deployment of new commercial services while protecting Federal
agency missions. This balances the needs of commercial operators with
the needs of Federal agencies for protection and future growth by
creating an environment where Federal and non-Federal users can share
the band on a co-primary basis and providing enough certainty to future
commercial users to stimulate investment in the spectrum.
3. Passive Services Below 37 GHz
86. The Commission believes that the out-of-band emission (OOBE)
limit that the Commission adopts in this Report and Order will provide
adequate protection to the passive sensors in the adjacent 36-37 GHz
band. The OOBE limit will keep emissions from an UMFUS device into the
36-37 GHz band well below the -10 dBW level specified by footnote
US550A. The Commission notes that the -10dBW power limit was adopted to
protect passive sensors in the 36-37 GHz band in accordance with ITU
Resolution 752 (WRC-07). Because this limit was adopted by the ITU to
protect passive sensors from harmful interference from fixed and mobile
transmitters in the 36-37 GHz band, the Commission concludes that it
will provide appropriate protection to the passive sensors from
transmitters in the adjacent band.
87. The Commission will not adopt a guard band at 37 GHz to protect
the EESS and SRS in the 36-37 GHz band as suggested by CORF and IEEE
Frequency Allocations in Remote Sensing (FARS). Neither CORF nor IEEE
FARS make a specific recommendation on the necessary size of the guard
band, although CORF requests a guard band of at least 100 MHz. Because
a guard band will reduce the spectrum available for mmW devices, the
Commission does not want to take this step without compelling evidence
that it is necessary. No one has provided information on the specific
benefits and necessity of adopting a guard band of at least 100 MHz to
protect EESS and SRS. Given the lack of data supporting adoption of a
guard band, the Commission believes that the out-of-band emission limit
that the Commission has adopted will provide adequate protection to the
EESS and SRS without the need for a guard band at 37 GHz.
88. With regard to protecting radio astronomy at the three
locations specified by CORF, the Commission is not convinced that
additional measures are needed to protect radio astronomy. The radio
astronomy observations that CORF is concerned about will be conducted
in the 36.43-36.5 GHz band, which is 500 megahertz from the 37 GHz
band, so the emission limits that the Commission is adopting for mmW
devices should sufficiently protect radio astronomy.

F. Licensing, Operating, and Regulatory Issues

1. Creation of New Rule Service and Part
89. The Commission adopted in its proposal to create a new service,
the UMFUS under a new part 30 of the Commission's rules to include the
28 GHz, 39 GHz, and 37 GHz bands. Licensing the millimeter wave bands
under part 27, as CTIA suggests, would produce a less flexible regime
than the Commission intend while the rules the Commission adopted in
part 30 will provide much of the flexibility present in the part 27
rules. Part 27 would be a poor fit for the point-to-point services
currently operating in the 28 and 39 GHz bands, and for the backhaul
uses other licensees may wish to include in their services. Part 96,
which Google suggests, is designed for a specific regime of intensive,
three-tier sharing. As the Commission is not adopting this type of
sharing regime for these bands at this time, using this rule part would
be inappropriate. The Commission concludes that establishing a new rule
part will allow us to have one unified set of rules governing the
various types of operations the Commission contemplates licensees will
offer, which will provide more clarity to licensees and more accurately
reflect the nature of these licenses.
2. Regulatory Status
90. The Commission adopted in its proposal from the NPRM to
implement a flexible regulatory framework for the UMFUS. As the
Commission proposed, UMFUS licensees in the 28, 39, and 37 GHz bands
will be able to choose the regulatory status (common carrier, non-
common carrier, or both) that best fits their business models and the
services they seek to provide. This approach will maintain an open and
flexible framework that will allow the business judgments of individual
applicants and licensees in these bands to shape the nature of the
services offered pursuant to their licenses.
91. The Commission also adopts its proposal to rely on the
applicant's designation of its common carrier or non-common carrier
status, to enable us to fulfill our obligations to enforce the common
carrier requirements contained in statutes and the Commission's
regulations. An election to provide service on a common carrier basis
requires that the elements of common carriage be present, and the
applicant is in the best position to ascertain the presence of these
elements. This approach is consistent with the Commission's past
decisions regarding the classification of mobile services.
3. Foreign Ownership Reporting
92. Certain foreign ownership and citizenship requirements are
imposed by subsections (a) and (b) of Section 310 of the Act, as
modified by the 1996 Act. These provisions prohibit the issuance of
licenses to certain applicants. For current LMDS, 37 GHz, and 39 GHz
licensees, these statutory provisions are adopted in part 101 of the
Commission's rules at Sec. 101.7 of the Commission's rules.
Specifically, Sec. 101.7(a) prohibits the granting of any license to
be held by a foreign government or its representative. Section 101.7(b)
prohibits the granting of any common carrier license to be held by
individuals that fail any of the four citizenship requirements listed.
93. In the NPRM, the Commission tentatively concluded that the
Section 310 requirements would apply to any applicants in the UMFUS.
Based on this interpretation of the requirements of Section 310, the
Commission proposed

[[Page 79909]]

in the NPRM to include a provision in the new part 30 that would mirror
the current Sec. 101.7 of the Commission's rules. In addition, the
Commission proposed that all applicants for part 30 licenses be
required to report the same foreign ownership information, regardless
of the specific type of service they sought to provide. An applicant
requesting authorization for broadcast, common carrier, aeronautical en
route, or aeronautical Fixed Services, alone or in combination with
other services, would be prohibited from holding a license if it met
any of the criteria in Section 310(b). If the applicant requested
authorization for services other than for broadcast, common carrier,
aeronautical en route, or aeronautical Fixed Services, it could hold a
license if it met the single alien ownership requirement in Section
310(a), regardless of whether it would otherwise be disqualified for a
common carrier authorization. No commenters addressed the issue of
foreign ownership reporting requirements, or opposed the Commission's
proposals.
94. The Commission adopted in its proposals from the NPRM to
require the same foreign ownership reporting from all applicants for
part 30 licenses, regardless of the specific type of service they seek
to provide, and to implement this requirement by including a provision
in part 30 that mirrors Sec. 101.7 of the Commission's current rules.
This approach will properly implement the restrictions contained in
Sections 310(a) and (b) of the Act, and is consistent with the
Commission's treatment of flexible use services regulated under part 27
of the Commission's rules.
4. Eligibility
95. In the NPRM, the Commission adopted an open eligibility
standard for the UMFUS. The Commission noted that an open eligibility
approach would not affect citizenship, character, or other generally
applicable qualifications that may apply under the Commission's rules.
Cisco and CTA support this proposal, citing uncertainty as to how the
UMFUS bands will develop, and the need to allow innovation from all
parties. No commenters opposed the Commission's proposal.
96. The Commission adopted its proposal to implement an open
eligibility standard for the UMFUS. This approach is in keeping with
the flexibility of the other licensing rules the Commission adopted in
this Report and Order, as well as the Commission's treatment of other
flexible use services, and will encourage innovation and efficient use
of spectrum in these bands.
5. License Term
97. The Commission adopted its proposal to establish a 10-year
license term for all UMFUS licenses, and the Commission's proposal to
award a renewal expectancy for subsequent license terms if the licensee
continues to provide at least the initially-required level of service.
While the Commission has pursued shorter license terms and non-
renewable licenses in other bands, and continue to believe there are
circumstances where those structures are appropriate, here the
Commission adopted a 10 year license term that can be renewed. The
Commission believes a 10-year license term will give licensees
sufficient certainty to invest in their systems, particularly as the
new technology is still nascent and will require time to fully develop.
If the standards for mobile service in the mmW bands are established
by, at the latest, 2020, new licensees would still have the majority of
the license term after that point to plan and to deploy service.
Neither XO nor any other commenter has presented facts that would
justify a longer license term. A 10-year license term is also
consistent with existing license terms in a wide variety of services.
98. The Commission also adopted in its proposal to award a renewal
expectancy for subsequent license terms if the licensee continues to
provide at least the initially-required level of service through the
end of any subsequent license terms. That treatment is consistent with
the Commission's treatment of many other licensed services and will
provide incentives for licensees to continue to provide service.
6. Mobile Spectrum Holdings Policies
99. The Commission found it essential to establish clear and
transparent mobile spectrum holdings policies that will promote
competition in the future, including competition in the development of
5G services, as well as promote the efficient use of mmW spectrum, and
avoid an excessive concentration of licenses. As mentioned in the NPRM,
demand for mobile service that mmW spectrum is expected to enhance and
improve has been increasing, and the Commission's predictive judgment
is that interest in the spectrum will be high. Thus, the Commission
finds that it would provide regulatory certainty, flexibility in
planning, and expedited deployment if the Commission supplies guidance
on application of these policies at this stage when the Commission
authorizes mobile service in these bands and adopt related rules
governing the terms of service, rather than at some later stage. In the
Commission's consideration of whether to adopt a mobile spectrum
holdings limit for the licensing spectrum through competitive bidding
and, if so, what type of limit to apply, the Commission's evaluation
includes, among other things, the promotion of competition in relevant
markets, the acceleration of private sector deployment of advanced
services, and generally managing the spectrum in the public interest.
The Commission evaluates how a limit would likely affect the quality of
communications services or result in the provision of new or additional
services to consumers, as well as any other statutory goals and
directives applicable to a particular spectrum band being licensed by
competitive bidding.
100. As the Commission noted in the Mobile Spectrum Holdings Report
and Order, the mobile wireless marketplace is highly concentrated, and
with continually increasing consumer demand for mobile broadband, ``in
order for there to be robust competition, multiple competing service
providers must have access to or hold sufficient spectrum to be able to
enter a marketplace or expand output rapidly in response to any price
increase or reduction in quality, or other change that would harm
consumer welfare.'' In addition, the Commission has found that holding
a mix of spectrum bands is advantageous to providers and that
consumers' benefit when multiple providers have access to a mix of
spectrum bands. The Commission concludes here that with, the rapid rate
of technological advance, mmW spectrum is likely to be a critical
component in the development of 5G, and the Commission must take steps
to ensure its optimal use to the benefit of all American consumers. For
these reasons, the Commission adopted an ex ante spectrum aggregation
limit of 1250 megahertz that will apply to licensees acquiring spectrum
in the 28 GHz, 37 GHz, and/or 39 GHz bands, through competitive bidding
in auction. The Commission adopted for these same reasons a spectrum
threshold of 1250 megahertz for proposed secondary market transactions
in these three bands.\6\
---------------------------------------------------------------------------

\6\ The Commission notes that this 1250 megahertz spectrum
threshold helps to identify those markets that provide particular
reason for further competitive analysis, but that the Commission's
consideration of potential competitive harms would not be limited
solely to those markets identified by the threshold.
---------------------------------------------------------------------------

101. Historically, mmW frequencies have been considered unsuitable
for

[[Page 79910]]

mobile applications because of propagation losses at such high
frequencies and the inability of mmW signals to propagate around
obstacles. As noted in the NPRM, bands above 24 GHz were not typically
considered for stand-alone mobile services but rather as supplementary
channels to deliver ultra-high speed data in specific places. Due to
technological advances, the mmW bands could potentially be used for
mobile broadband and are likely to serve as an important supplement to
lower-band spectrum. Specifically, the mmW bands potentially will be
used for supporting very high capacity networks in areas that require
such capacity, as well as for machine-to-machine communications, and in
the development of various Internet of Things (IoT) applications
including wearables, fitness and healthcare devices, autonomous driving
cars, and home and office automation.
102. The Commission finds that grouping the 28 GHz, 37 GHz, and 39
GHz bands together for purposes of applying these spectrum holdings
policies, either at auction or in the secondary market, is appropriate
in view of the interchangeability of the spectrum in these bands, i.e.,
similar technical characteristics and potential uses of this spectrum
that are unique to the mmW bands. While certain differences across the
mmW bands exist, the Commission finds these technical differences are
not sufficient to significantly affect how these spectrum bands might
be used and to require separate band-specific limits. This approach
mirrors the Commission's existing Commercial Mobile Radio Service
(CMRS) spectrum screen, which applies across a number of bands that do
not have the same technical characteristics and not on a band-specific
basis. Even assuming that more 37 GHz to 39 GHz spectrum would be
needed to provide the same performance, there will be 2400 megahertz of
37 GHz and 39 GHz spectrum available for service providers' use, almost
three times as much as in the 28 GHz band. And, in any event, all the
particular facts of any proposed secondary market transaction will be
carefully evaluated on a case-by-case basis to ensure that the public
interest is served. For these reasons, the Commission does not find
that adopting a band-specific spectrum aggregation limit is necessary,
and the Commission finds that the spectrum holdings policies adopted in
the Report and Order will best support its objective of ensuring that
multiple providers have access to this high band spectrum that is
likely to be critically important in the development of 5G services
moving forward. The Commission anticipates that applying these spectrum
holdings policies to spectrum with similar technical characteristics
that may become available in the future is also likely to be
appropriate.
103. Competitive Bidding. The Commission concludes that an approach
based on limiting an entity's holding to approximately one-third of the
relevant spectrum will help to ensure that multiple providers are able
to access a sufficient amount of spectrum to the benefit of consumers.
In the Commission's consideration of the appropriate limit to set at
auction, the Commission notes that as a result of the various license
sizes in these bands, setting a limit at approximately one-third would
as a practical matter result in a limit notably lower than a one-third
limit.\7\ Given the varied license sizes of spectrum blocks in each
band, as well as the total amount of mmW spectrum available, the
Commission finds that permitting licensees to acquire somewhat more
than one-third of the spectrum available in these bands at auction is
appropriate. The Commission therefore will not permit licensees to
acquire more than 1250 megahertz across the three bands at auction.\8\
The Commission finds that the spectrum aggregation limit the Commission
adopted will help ensure that multiple providers will be able to access
a sufficient amount of mmW spectrum to facilitate the deployment of new
services and innovation that will benefit consumers, while guarding
against the excessive concentration of licenses. The Commission asks
for comment below on how this limit might be implemented.
---------------------------------------------------------------------------

\7\ The total available amount of the mmW spectrum in the 28
GHz, 37 GHz, and 39 GHz bands today is equal to 3250 megahertz,
approximately one-third of which is 1100 megahertz. Given the sizes
of the spectrum blocks in these bands, however, no entity could hold
more than 1050 megahertz, and an entity interested in holding only
licenses in the 37 and 39 MHz bands could hold no more than 1000
megahertz. More specifically, the latter entity would be able to
hold no more than five licenses of 200 megahertz each across the 37
GHz and 39 GHz bands for a total of 1000 megahertz. An entity
interested in holding some 28 GHz spectrum could hold either two 28
GHz licenses and one license of 200 megahertz for a total of 1050
megahertz, or one 425 megahertz license in the 28 GHz band and three
licenses of 200 megahertz for a total of 1025 megahertz.
\8\ The Commission recognizes that there are incumbent licensees
in the 28 GHz and 39 GHz bands that currently hold varying amounts
of spectrum. These licensees would be able to bid in the auction to
an amount that would be no more than 1250 megahertz in total, taking
existing spectrum holdings into account. Service providers' existing
spectrum holdings across the 28 GHz, 37 GHz, and 39 GHz bands
therefore will be counted for purposes of the Commission's
application of the 1250 megahertz limit.
---------------------------------------------------------------------------

104. Secondary Market. The Commission adopted its proposal to
exclude mmW spectrum from the current spectrum screen that includes
those spectrum bands that the Commission has determined are suitable
and available for the provision of mobile telephony/broadband services.
As the Commission has previously explained, spectrum is considered
``available'' if it is ``fairly certain that it will meet the criteria
for suitable spectrum in the near term, an assessment that can be made
at the time the spectrum is licensed or at later times after changes in
technology or regulation that affect the consideration.'' The
Commission does not find that the mmW bands are suitable and available
for the provision of mobile telephony/broadband services in the same
manner as other spectrum bands that are currently included in the
Commission's spectrum screen as applied to secondary market
transactions. The Commission makes this finding based on the unique
characteristics of these bands as described above. Accordingly, the
Commission does not include the mmW bands in the spectrum screen.
105. However, the Commission recognizes that this frontier spectrum
is likely to become increasingly valuable to the advent of 5G services.
In its competitive analysis of wireless transactions, the spectrum
screen applicable to lower-band spectrum has been one tool used to help
identify particular markets for further competitive analysis; it is
applied on a county-by-county basis and identifies local markets where
an entity would hold approximately one-third or more of the total
spectrum suitable and available for the provision of mobile telephony/
broadband services, post-transaction. Similarly, for proposed secondary
market transactions that would result in an entity holding 1250
megahertz or more of the total spectrum in the 28 GHz, 37 GHz, and 39
GHz bands, the Commission will apply its threshold on a county-by-
county basis, and subject such transactions to the Commission's case-
by-case review in order to ensure that the public interest is served.
As noted above, while this 1250 megahertz spectrum threshold helps to
identify those markets that provide particular reason for further
competitive analysis, the Commission's consideration of potential
competitive harms will not be limited solely to those markets
identified by the threshold. Establishing this spectrum aggregation
threshold in the secondary market context recognizes the specific
characteristics of the

[[Page 79911]]

spectrum while helping to ensure that multiple entities have an
opportunity to obtain mmW spectrum for deployment of innovative mobile
technologies.
106. Summary. The Commission finds, on balance, that the potential
public interest benefits of adopting a 1250 megahertz limit for
auctions of this spectrum, and a 1250 megahertz threshold for secondary
market transactions for these unique spectrum bands outweigh any
potential public interest harms. Further, adopting these spectrum
holdings policies is consistent with the Commission's previous
determination that an ``approximately one-third threshold for total
spectrum that the Commission uses to identify those holdings in local
markets that may raise particular competitive concerns'' is an
effective analytical tool in the secondary market context. The
Commission anticipates that the potential costs of adopting such
spectrum holdings policies will be low. The Commission disagrees with
commenters who argue that it is premature for the Commission to
establish any spectrum aggregation policies in these bands and that
such policies will undermine the potential use of this spectrum. On the
contrary, the Commission finds that establishing such policies that
will apply as mmW spectrum is introduced into the marketplace will help
promote competition from the outset. The Commission has explained that
mmW spectrum holds the potential for a range of uses from supporting
high capacity networks to use with various IoT applications. While the
Commission cannot be certain at this time how this spectrum will be
used, the Commission finds that its anticipated value to the future of
5G makes it critical that multiple providers have access to it. The
spectrum holdings policies the Commission adopted will guard against
consolidation of this spectrum by one or two providers and will
encourage the development of innovative services to the benefit of the
American consumer.
7. Performance Requirements
a. Performance Metrics and Milestones
107. The Commission declines to adopt a unified performance metric
at this time. Based on the criticisms and alternative suggestions in
the record, the Commission concludes that such an approach would not
provide the flexibility necessary to support innovative uses of the
spectrum, as it would favor one deployment approach over another. A
unified approach might also deter investment and deployment in these
bands. The Commission also declines to adopt a ``substantial service''
standard of performance for the UMFUS. The Commission determines that
such a standard, with no firm minimum requirements, would not
adequately safeguard effective use of spectrum in these bands. The
Commission also declines to adopt a usage-based metric for performance
requirements because it is not clear that there is a workable method of
measuring or enforcing such a requirement. Instead, the Commission
adopted a series of metrics, tailored for each type of service a
licensee might choose to offer. Licensees may fulfill their performance
requirements by showing that they meet their choice of any one of the
below standards, or a combination of several. This framework is
intended to provide enough certainty to licensees to encourage
investment and deployment in these bands as soon as possible, while
retaining enough flexibility to accommodate both traditional services
and new or innovative services or deployment patterns. Its increased
level of firmness over a substantial service metric is also consistent
with the Commission's recent approach in other services.
108. The Commission notes that this list of metrics is not intended
to be exhaustive. The Commission recognizes that the metrics the
Commission adopted does not cover all possible types of service that
licensees may seek to offer in these bands, and that new, innovative
services may be developed with different characteristics that the
Commission cannot foresee at this time. The Commission therefore seeks
further comment in the FNPRM on additional metrics that should be
applied to these innovative services.
109. The Commission adopted these performance requirements only in
relation to the end of the initial license terms in these bands.
Because the Commission believes it is taking action with significant
lead time before the full development of the technology, the Commission
believes an interim benchmark might be difficult to meet and may result
in a substantial number of waiver and extension requests. While the
Commission does not adopt any ongoing or subsequent performance
requirements at this time, the Commission strongly encourages licensees
to deploy networks and services in a timely manner consistent with the
development of the technology for these bands. The Commission
emphasizes, however, that the Renewal and Service Continuity proceeding
(WT Docket No. 10-112), which addresses this issue, remains open, and
that licensees may be subject to any requirements adopted as part of
that proceeding at some later date.
110. Mobile and point-to-multipoint. For mobile and point-to-
multipoint services in the 28 GHz, 37 GHz (geographic area licenses
only), and 39 GHz bands, the Commission adopted a modified version of
the Commission's proposal in the NPRM. In order to meet the standards
for license renewal, a licensee providing mobile service must provide
coverage to 40 percent of the population of the license area and must
be using the facilities to provide service. This is a lower portion of
the population than is the standard for lower frequency bands because
this level of coverage strikes the appropriate balance between ensuring
sufficient use of the spectrum and allowing licensees flexibility to
deploy an emerging technology which may be more suitable for smaller
coverage areas. The Commission views the current safe harbor of 20
percent population coverage as inappropriate going forward because the
new technologies being developed will dramatically increase the
opportunities to use these bands. Since the Commission is not requiring
service demonstrations until the end of the license term, the
Commission believes licensees will have more than adequate time to meet
this benchmark. Similarly, the Commission does not believe CTIA's
suggestions of 10 ``connections'' per 10,000 population, or 50
connections per county, will result in robust build out in these bands.
Under CTIA's proposed definition of a ``connection,'' these 10
connections could represent as little as one subscriber accessing the
network 10 times in one month. This is a particularly low benchmark for
mobile operations, which is one of the primary target use cases for
this new service. The Commission does not believe this standard
represents a sufficient level of service to justify renewal.
111. The Commission declines to adopt the measurement method the
Commission proposed in the NPRM and concludes that requiring a specific
methodology is unnecessary. Instead, the Commission will provide
licensees with flexibility in terms of how they make their service
showings, but Commission staff will continue to review showings to
ensure that they accurately reflect coverage.
112. Fixed. The Commission does not adopt its proposed method of
``keyhole contours'' for assigning fixed links a population equivalent.
Instead, the Commission adopted a more traditional method of
demonstrating fixed service: the number of links per population in the
license area. Specifically, the Commission adopted a requirement that

[[Page 79912]]

geographic area licensees providing Fixed Service in the 28 GHz, 39
GHz, or 37 GHz bands must construct and operate at least four links in
license areas with less than 268,000 population, and at least one link
per 67,000 population in license areas with greater population. This
standard is similar to the standard the Commission established for
fixed point-to-point services in the 2.3 GHz band. While links in mmW
bands will presumably be shorter because of the propagation
characteristics, the higher frequencies will allow more reuse of
spectrum in a given area. These links must be part of a network that is
actually providing service, whether to unaffiliated customers or
private, internal uses, and all links must be present and operational
at the end of the license term. As with the mobile performance
milestone, for bands licensed by areas larger than counties the number
of links and the size of the population will be calculated over the
entire license area, not county by county.
113. Satellite. The Commission adopted it proposal from the NPRM. A
licensee who purchases a 28 GHz UMFUS license may fulfill build-out
requirements for the license by deploying an earth station in the
license area that is operational and providing service. The Commission
notes that a licensee may not fulfill this requirement by leasing a
portion of its license area to a satellite operator that builds and
operates an earth station within the leased area. In 37 and 39 GHz,
because the Commission adopted significantly larger geographic license
areas than counties, constructing and operating an earth station will
fulfill the performance requirement only for the county in which it is
constructed, and not for the entire license area. Satellite operators
who develop earth stations under the satellite sharing mechanisms the
Commission adopted for the 28 GHz and 39 GHz bands will continue to be
subject to the applicable part 25 build-out requirements.
114. Combination. Licensees whose deployments contain a mix of
services, for example mobile service combined with fixed backhaul may
meet the relevant fixed or mobile/point-to-multipoint standard
separately. The Commission declines to establish a specific formula for
evaluating such buildouts on a combined basis. Instead, the Commission
will evaluate such showings on a case-by-case basis, as the Commission
has done for LMDS.
b. Failure To Meet Buildout Requirements
115. The Commission adopted a modified version of its proposal,
tailored to the different license area sizes the Commission adopted for
each band. For all bands, the Commission adopted its proposal to
terminate licenses (or portions of licenses, as appropriate)
automatically if a licensee fails to meet the applicable performance
requirements, which is widely applied in many wireless services. The
band-specific approaches to license renewal and termination are
explained in more detail below. In the accompanying FNPRM, the
Commission seeks to further develop the record on use-or-share
obligations.
116. 28 GHz. The 28 GHz band will be licensed by county because
partitioning licenses in these bands into license areas smaller than
counties would be administratively burdensome without providing any
off-setting benefits to licensees or service providers. Accordingly, if
a licensee in the 28 GHz band fails to meet the applicable performance
requirements at the end of its license term, the license for that
county will terminate immediately in its entirety. As the Commission is
reissuing the licenses in these band by county rather than by BTA, the
Commission declines to implement EchoStar's proposal to continue to
evaluate incumbent licensees' performance on a BTA-wide basis.
117. 37 and 39 GHz. The 39 GHz band, as well as the 37.6-38.6 GHz
band, will be licensed by PEAs, rather than counties. In order to
balance the need to ensure productive use of spectrum with the need to
encourage investment and deployment, the Commission adopted a modified
approach to performance requirements in this band.
118. A licensee who meets the applicable performance requirements
for the entire PEA, taken as a whole, will be eligible to renew the
entire license. A licensee who does not meet the requirements for the
entire license area will have two options: (1) automatic termination of
the entire license, or (2) partition the license at the county level,
and return a portion of the license to the Commission such that the
applicable performance requirements are met for the remaining non-
forfeited area. For example, a licensee of a PEA containing five
counties of 100,000 people each, who deployed mobile service covering
60 percent of the population in each of two counties, and made no
deployments in the other three counties, would be covering only 24
percent of the total population of the license area. This would not be
enough to meet performance requirements across the entire license.
However, the licensee could forfeit the portion of the license covering
the three un-deployed counties, and retain and renew the portion of the
license covering the remaining two counties. Similarly, a licensee of
the same hypothetical PEA who deployed mobile service covering 80
percent of one county, and 30 percent of another, could retain and
renew the portion of the license for those two counties because the
resulting two-county license area would have coverage of 55 percent of
its population, which exceeds the 40 percent requirement.
c. Treatment of Incumbents
119. The Commission declines to adopt its proposal from the NPRM.
For license terms concluding before 2020, licensees may be unable as a
practical matter to meet the new, more rigorous requirements the
Commission adopted for these bands at the end of their current license
terms because of the nascent state of technology. Moreover, providing
for additional time will provide more effective opportunities for
licensees to use the spectrum in ways that maximize the flexibility now
afforded by the Commission's new rules. For example, the transition
toward providing innovative mobile services is likely to require
complex business decisions and changes in plans. In short, it is the
Commission's intent to encourage deployment of new and innovative
services--particularly mobile service--as efficiently and effectively
as possible.
120. Thus, the Commission slightly modifies and extends the
deadline for meeting the performance requirements pertaining to
licensees' current licenses for licenses expiring after the adoption
date of the rules in this proceeding. Specifically, current licensees
in the 28 GHz and 39 GHz bands who, under the current rules, face a
deadline for demonstrating substantial service after the adoption date
of this Report and Order will not be required to demonstrate
substantial service at renewal. Instead, those licensees will be
required to fulfill the performance requirements the Commission adopted
for their respective licenses by June 1, 2024. This approach will allow
current licensees to focus on growing and transitioning their networks
in line with new and developing industry standards, which will support
earlier and more robust deployment of next-generation services in these
bands.

[[Page 79913]]

d. Alternatives to Performance Requirements
121. The Commission declines to adopt either of these alternatives
for these bands. The Communications Act contemplates that the
Commission will take measures ``to prevent stockpiling or warehousing
of spectrum by licensees.'' The Commission believes the foregoing
performance requirements are feasible in these bands, and the best
method to prevent warehousing in this context. O3b argues that such
``consecutive license terms with recurring payments'' would simply
change the financial calculation underpinning warehousing: while the
initial bid would be smaller and discounted less, the lower price of
entry could encourage warehousing by reducing the amount initially
needed to hold on to the spectrum. In the absence of any discussion of
the ``option payment'' concept, the Commission will not adopt the
proposal at this time.
8. Permanent Discontinuance of Operations
122. Under Sec. 1.955(a)(3) of the Commission's rules, an
authorization will automatically terminate, without specific Commission
action, if service is ``permanently discontinued.'' In the NPRM, the
Commission proposed that for UMFUS licensees that identify their
regulatory status as common carrier or non-common carrier,
``permanently discontinued'' should be defined as a period of 180
consecutive days during which the licensee does not provide service to
at least one subscriber that is not affiliated with, controlled by, or
related to, the provider in the service area of its license (or smaller
service area in the case of a partitioned license).
123. The Commission proposed a different approach for licensees
that use their licenses for private, internal communications. For these
services, the Commission proposes to define ``permanent
discontinuance'' as a period of 180 consecutive days during which the
licensee does not operate any facilities under the license. The
Commission proposed that licensees not be subject to this requirement
until one year after their initial license period ends, to allow them
adequate time to construct their networks.
124. The Commission also proposed that when 28 GHz, 37 GHz, or 39
GHz licensees permanently discontinue service, the licensee must notify
the Commission of the discontinuance within 10 days, by filing FCC Form
601 and requesting license cancellation. The Commission further
proposed that an authorization automatically terminates without
specific Commission action if service is permanently discontinued, even
if a licensee fails to file the required form. No commenters discuss
the permanent discontinuance of service proposals.
125. The Commission adopted its proposals from the NPRM related to
permanent discontinuance of operations. Specifically, the Commission
adopted the two separate proposed definitions of ``permanent
discontinuance,'' for common carrier and non-common carrier service,
and for private communications services. The Commission also adopted
its proposal to wait to implement this requirement until one year after
the initial license period ends. This approach is consistent with the
definitions the Commission has adopted for other spectrum bands that
are licensed for mobile use, including the H Block, AWS-3, and AWS-4
bands.
126. The Commission also adopted its proposal that a licensee who
permanently discontinues service must notify the Commission within 10
days, and the Commission's proposal that such licenses terminate
automatically even if a licensee fails to appropriately notify the
Commission. This approach to permanent discontinuance is consistent
with Sec. 1.955(a)(3) of the Commission's rules. The permanent
discontinuance rule is intended to provide operational flexibility
while ensuring that spectrum does not lie idle for extended periods,
and the rules the Commission adopted support those goals.
9. Secondary Markets Policies
a. Partitioning and Disaggregation
127. The Commission's part 101 rules generally allow for geographic
partitioning and spectrum disaggregation in the LMDS and 39 GHz
service. Geographic partitioning refers to the assignment of geographic
portions of a license to another licensee along geopolitical or other
boundaries. Spectrum disaggregation refers to the assignment of
discrete amounts of spectrum under the license to another entity.
Disaggregation allows for multiple transmitters in the same geographic
area operated by different companies on adjacent frequencies in the
same band.
128. In 1997, the Commission determined that all LMDS licensees
would generally be permitted to disaggregate and partition their
licenses. The Commission later adopted specific procedural,
administrative, and operational rules to govern the disaggregation and
partitioning of LMDS licenses. Similarly, in the same year, the
Commission concluded that partitioning and disaggregation would be
permitted in the 39 GHz band and adopted partitioning and
disaggregation rules in this band as well. The rules require the
spectrum to be disaggregated by FDD pair in the 39 GHz band.
129. In the NPRM, the Commission proposed to continue to allow
partitioning and disaggregation in the 28 and 39 GHz bands, and to
permit 37 GHz licensees to partition and disaggregate their licenses as
well. The Commission also proposed to require all parties to a
partitioning or disaggregation agreement to independently fulfill the
applicable performance and renewal requirements, which is consistent
with the current requirements.
130. Commenters overwhelmingly support allowing secondary market
transactions in general, and partitioning and disaggregation in
particular. Intel supports expanding disaggregation in the 39 GHz band
by also permitting pair-splitting. No commenters oppose allowing
secondary market transactions generally, or partitioning or
disaggregation specifically. No commenters discuss performance
requirements for parties to a partition or disaggregation.
131. The Commission adopted its proposal in the NPRM to allow
partitioning and disaggregation of licenses in the 28, 37, and 39 GHz
bands. As the Commission noted when first establishing partitioning and
disaggregation rules, allowing such flexibility could facilitate the
efficient use of spectrum by enabling licensees to make offerings
directly responsive to market demands for particular types of services,
increasing competition by allowing new entrants to enter markets, and
expediting provision of services that might not otherwise be provided
in the near term. This policy would leave the decision of determining
the correct size of licenses to the licensees and the marketplace.
Allowing this flexibility is consistent with the record, and with the
flexible approach to licensing these bands that the Commission adopted
in this Report and Order. Because the band plan the Commission adopted
for the 39 GHz band does not use paired spectrum blocks, the current
rule that licenses in that band must be disaggregated in pairs will no
longer apply.
132. The Commission also adopted its proposal to require all
parties to a partitioning or disaggregation agreement to independently
fulfill applicable performance and renewal requirements. According to
the performance requirements framework the Commission adopted,
individual

[[Page 79914]]

licensees may choose which metric they fulfill (e.g., fixed, mobile, or
satellite), but each licensee must make a showing that independently
satisfies the requirements. This requirement will facilitate efficient
spectrum use, while enabling service providers to configure geographic
area licenses and spectrum blocks to meet their operational needs.
b. Spectrum Leasing
133. In 2003, in order to promote more efficient use of terrestrial
wireless spectrum through secondary market transactions and in order to
eliminate regulatory uncertainty, the Commission adopted the Secondary
Markets First Report and Order, which contained a comprehensive set of
policies and rules to govern spectrum leasing arrangements between
terrestrial licensees and spectrum lessees. These policies and rules
enabled terrestrially-based Wireless Radio Service licensees holding
``exclusive use'' spectrum rights to lease some or all of the spectrum
usage rights associated with their licenses to third party spectrum
lessees. Those third party lessees were then permitted to provide
wireless services consistent with the underlying license authorization.
134. This 2003 Order excluded a number of wireless radio services
from the spectrum leasing rules and policies, including part 101
services. A year later, the Commission extended the spectrum leasing
policies to a number of additional wireless services, including part
101 services. At that time, the Commission also built upon the spectrum
leasing framework by establishing immediate approval procedures for
certain categories of terrestrial spectrum leasing arrangements.
135. In the NPRM, the Commission proposed to apply these spectrum
leasing policies to the new part 30 radio service governing UMFUS's,
including all 28 GHz, 37 GHz, and 39 GHz terrestrial licenses. The
Commission proposed to apply these policies in the same manner that
they apply to part 101 services.
136. Many commenters support allowing secondary market transactions
generally and spectrum leasing specifically. Commenters cite the
additional flexibility afforded by leasing spectrum, and the market
certainty granted by using established rules. Several commenters also
mention that spectrum leasing allows a broader range of entities to
access licensed spectrum and provides additional competition in the
marketplace. No commenters oppose allowing spectrum leasing
arrangements.
137. The Commission adopted its proposal to allow spectrum leasing
in the 28 and 39 GHz bands, as well as the portion of the 37 GHz band
licensed on a geographic area basis. Allowing spectrum leasing in these
bands will promote more efficient, innovative, and dynamic use of the
spectrum, expand the scope of available wireless services and devices,
enhance economic opportunities for accessing spectrum, and promote
competition among providers. In addition, spectrum leasing policies in
a particular band generally follow the same approach as the
partitioning and disaggregation policies for that band. Thus, the
Commission's adoption of spectrum leasing rules for the 28 GHz, 39 GHz,
and 37 GHz bands is consistent with the Commission's decision above to
allow partitioning and disaggregation in these bands as well.
10. Other Operating Requirements
138. The Commission adopted its proposal in the NPRM to require
UMFUS licensees to comply with other rule parts that pertain generally
to wireless communications services, and with any applicable service-
specific rules. This approach will maintain general consistency among
various wireless communications services. Consistent with the
Commission's proposal, the Commission will add UMFUS to the definitions
of Wireless Radio Service and Wireless Telecommunications Service in
Sec. 1.907 of the Commission's rules. The Commission refrains from
modifying other existing rules in other rule parts at this time, as no
commenter has identified any incompatibilities or inconsistencies
between the UMFUS Service and the existing service-specific or
generally applicable rules. To consolidate the technical rules for all
of the types of flexible uses that might be deployed by UMFUS licensees
under a single rule part, and to maintain consistency between the rules
that the Commission adopted and the current technical requirements that
existing LMDS and 39 GHz licensees are subject to, the Commission will
move the existing part 101 technical rules for traditional point-to-
point and point-to-multipoint operations into part 30.
11. Competitive Bidding Procedures
a. Applicability of Part 1 Competitive Bidding Rules
139. The Commission proposed in the NPRM to conduct any spectrum
auction of UMFUS licenses in conformity with the general competitive
bidding procedures set forth in part 1 subpart Q of the Commission's
rules. No commenters proposed any alternative or objected. Given the
Commission's experience in successfully conducting auctions using these
procedures, the Commission adopted its proposed approach. The
Commission will employ the part 1 rules governing competitive bidding
design, designated entity preferences, unjust enrichment, application
and payment procedures, reporting requirements and the prohibition on
certain communications between auction applicants--including those
updates made in the Competitive Bidding Update Report and Order. The
Commission notes however, that the Commission could modify these
procedures at a later time.
140. In discussing the competitive bidding rules, one commenter
urges that if the Commission adopts county-level licenses, it would be
critical to permit `package bidding' so that operators could assemble
larger footprints by bidding on multiple counties at one time. In
response, two commenters argue that the Commission should not permit
any form of package bidding because such bidding procedures may make it
more difficult for small bidders to acquire specific licenses that are
included in larger packages. Issues involving such bidding procedures
are more appropriately addressed in a pre-auction proceeding that will
seek public input on the competitive bidding procedures to be used for
a particular auction of UMFUS licenses. Accordingly, the Commissions
defer consideration of such matters to such proceeding(s) where
interested parties are likely to have a more informed context for such
input.
b. Small Business Provisions for Geographic Area Licenses
141. In authorizing the Commission to use competitive bidding,
Congress mandated that the Commission ``ensure that small businesses,
rural telephone companies, and businesses owned by members of minority
groups and women are given the opportunity to participate in the
provision of spectrum-based services.'' One of the principal means by
which the Commission fulfills this mandate is through the award of
bidding credits to small businesses. In the Competitive Bidding Second
Memorandum Opinion and Order, the Commission stated that it would
define eligibility requirements for small businesses on a service-
specific basis, taking into account the capital requirements and other
characteristics of each particular service in establishing the
appropriate threshold. Further, in the Part 1 Third Report and Order
and the more recent Competitive Bidding

[[Page 79915]]

Update Report and Order, the Commission, while standardizing many
auction rules, determined that it would continue a service-by-service
approach to defining small businesses. The Commission recently updated
its standardized schedule of small business definitions to reflect the
capital challenges small businesses face in the current wireless
industry, and in the NPRM the Commission sought comment on whether to
apply those updated definitions for auctions of spectrum in the UMFUS
bands.\9\
---------------------------------------------------------------------------

\9\ Under the new standardized schedule, businesses with average
annual gross revenues for the preceding three years not exceeding $4
million would be eligible for a 35 percent bidding credit,
businesses with average annual gross revenues for the preceding
three years not exceeding $20 million would be eligible for a 25
percent bidding credit, and businesses with average annual gross
revenues for the preceding three years not exceeding $55 million
would be eligible for a 15 percent bidding credit. The Commission
also adopted a monetary cap on the total amount of bidding credits
that an eligible small business or rural service provider may be
awarded in any particular auction. Specifically, the amount of the
bidding credit cap for a small business in any particular auction
will not be less than $25 million and the bidding credit cap for the
total amount of bidding credits that a rural service provider may be
awarded will not be less than $10 million.
---------------------------------------------------------------------------

142. Based on the Commission's prior experience with the use of
bidding credits in spectrum auctions, the Commission believes that the
using bidding credits is an effective tool to achieve the statutory
objective of promoting participation of designated entities in the
provision of spectrum-based service.
143. In adopting competitive bidding rules for the 39 GHz band, the
Commission included provisions for designated entities to promote
opportunities for small businesses, rural telephone companies, and
businesses owned by members of minority groups and women to participate
in the provision of spectrum-based services. Specifically, the
Commission adopted bidding credits for applicants qualifying as small
businesses. For auction of licenses in the 39 GHz band, the Commission
adopted two small business definitions. These two small business
definitions were later adopted as the highest two of three thresholds
in the Commission's standardized schedule of bidding credits. In the
NPRM, the Commission proposed to adopt for the UMFUS the two small
business definitions with higher gross revenues thresholds reflecting
the recently adopted updates to the part 1 schedule of small business
definitions in the Competitive Bidding Update Report and Order. The
Commission adopted its proposal to apply the two small business
definitions with higher gross revenues thresholds to auctions of UMFUS
licenses in the 28, 37, and 39 GHz bands and any other spectrum bands
that the Commission may subsequently designate for inclusion in the
UMFUS. Accordingly, an entity with average annual gross revenues for
the preceding three years not exceeding $55 million will qualify as a
``small business,'' while an entity with average annual gross revenues
for the preceding three years not exceeding $20 million will qualify as
a ``very small business.'' While the capital requirements of the
services to be deployed in these bands is not yet known, the Commission
believes that using these gross revenue thresholds will enhance the
ability of small businesses to acquire and retain capital and thereby
complete meaningfully at auction. The Commission also believes that
these thresholds are not overly inclusive, and prevents designated
entity benefits from flowing to entities for which such credits are not
necessary. The Commission believes that the various spectrum bands
included in the UMFUS--spectrum that will be utilized under the same or
similar technical rules--will be deployed for the same types of
service, and therefore the two small business definitions with higher
gross revenues thresholds should apply to all of the bands in the
UMFUS.
144. The Commission also adopted its proposal to provide qualifying
``small businesses'' with a bidding credit of 15 percent and qualifying
``very small businesses'' with a bidding credit of 25 percent,
consistent with the standardized schedule in part 1 of the Commission's
rules. This proposal was modeled on the small business size standards
and associated bidding credits that the Commission adopted for a range
of other services, including Advanced Wireless Services in the AWS-1
band. The Commission believes that this two-tiered approach has been
successful in the past, and will once again utilize it. The Commission
uses the existing 39 GHz service rules as a starting point, but adjusts
the bidding credit levels to be consistent with the schedule in part 1
of the Commission's rules. The Commission believes that use of the
small business definitions and associated bidding credits set forth in
the part 1 bidding credit schedule will provide consistency and
predictability for small businesses. No commenter provides any
alternative or reason why the Commission's bidding credit thresholds or
small business definitions would not work in this service. Accordingly
the Commission adopted its proposals regarding small business
definitions and bidding credits.
c. Rural Service Provider Provisions for Geographic Area Licenses
145. The rural service provider bidding credit awards a 15 percent
bidding credit to those servicing predominantly rural areas and that
have fewer than 250,000 combined wireless, wireline, broadband and
cable subscribers. In the NPRM, the Commission stated that in the
absence of comments to the contrary, the Commission would leave open
the option for future bidding applicants to apply for rural service
provider bidding credits in lieu of a small business bidding credits.
The Commission now decides that the Commission will apply the rural
service provider bidding credit to auctioning the 28 GHz, 37 GHz and 39
GHz bands. Although the Commission has not received comments about this
issue, the Commission believes that a targeted bidding credit will
better enable rural service providers to compete for spectrum licenses
at auction and in doing so, will increase the availability of 5G
service in rural areas.
d. Small Business and Rural Service Provider Bidding Credit Caps
146. In the Competitive Bidding Update Report and Order, the
Commission adopted a process for establishing a reasonable monetary
limit or cap on the amount of bidding credits that an eligible small
business or rural service provider may be awarded in any particular
auction. The Commission established the parameters to implement a
bidding credit cap for future auctions on an auction-by-auction basis.
Consistent with the Commission's longstanding approach, after adoption
of all of the necessary service rules for the UMFUS, the Commission
will initiate a public notice process to solicit public input on
certain details of auction design and the auction procedures for the
initial auction of UMFUS licenses. As part of that process, the
Commission will solicit public input on the appropriate amount of the
bidding credit cap and subsequently establish the cap that will apply
for that auction, based on an evaluation of the expected capital
requirements presented by the particular spectrum being auctioned and
the inventory of licenses to be auctioned.
e. Tribal Lands Bidding Credit
147. The tribal lands bidding credit program awards a discount to a
winning bidder for serving qualifying tribal land that have a wireline
telephone

[[Page 79916]]

subscription rate equal to or less than 85 percent of the population.
The Commission believes that tribal entities involved in the
telecommunications industry face unique challenges in participating in
spectrum auctions and that the tribal lands bidding credit will promote
further deployment and use of spectrum over tribal lands. No commenters
oppose the tribal land bidding credit nor suggest that the tribal lands
bidding credit is unnecessary. Accordingly, a winning bidder for a
market will be eligible to receive a credit for serving qualifying
Tribal lands within that market, provided it complies with the
applicable competitive bidding rules.
f. Bidding Process Options
148. Finally, the Commission also sought comment in the NPRM on
whether the Commission should revise any of the Commission's bidding
process and payment rules to ameliorate the administrative difficulties
the Commission could potentially face in enforcing the construction
requirements in the 3,143 counties nationwide. One alternative the
Commission discussed was to allow prospective millimeter wave licensees
to bid, in a single auction, on licenses that have consecutive terms of
license rights in a given geographic area--i.e., licensees could bid at
auction for the right to obtain a license in a given county not just
for a single license term, but for each subsequent five-year license
term; and the winning bidder would pay an auction-determined fee, in
lieu of other performance requirements before the start of each term.
Once a winning bidder made this payment, a new license would issue for
the next consecutive license term. Some commenters support adopting
such payments in lieu of performance requirements. However several
commenters criticize the approach as incentivizing spectrum
warehousing. For example, O3b notes that consecutive license terms with
recurring payments would simply change the financial calculation
underpinning warehousing: while the initial bid would be smaller and
discounted less, the lower price of entry could encourage warehousing
by reducing the amount initially needed to hold on to the spectrum. The
Commission declines to adopt recurring payments as an alternative to
performance requirements in this order and note it is unlikely the
Commission would adopt such payments given the Commission's review of
the record and further consideration of the factors affecting these
bands. In the NPRM, the Commission speculated that these payments could
incentivize deployment of network facilities and discourage spectrum
warehousing because a licensee would be unlikely to pay the auction
price for successive terms for spectrum it did not intend to use.
However, the Commission believes there is a strong likelihood that
bidders would still warehouse spectrum and leave it fallow if the cost
of the recurring payment to the spectrum holder was outweighed by the
benefit derived from foreclosing other operators' access to the
spectrum. This would counter the Commission's goal of accelerating
deployment in these bands. Accordingly the Commission declines to adopt
this proposal.
12. Security
149. The FCC's approach to cybersecurity proceeds from the view
that communications providers are generally in the best position to
evaluate and address risks to their network operations. This approach
recognizes the importance of private sector leadership and innovation
in cybersecurity, and it reduces the need for ongoing regulatory
involvement in private sector security practices. It will prove
successful, though, only if the private sector aggressively addresses
evolving threats through security-by-design, even where short-term
market incentives may not be sufficient to drive long-term security
investments before harm is realized.
150. Emerging security standards for new flexible uses of the mmW
bands (and ``5G'' more broadly) are developing in parallel, but not
necessarily at the same pace, with the emerging networks, devices, and
equipment. While CTIA has observed that significant, multi-stakeholder,
multi-disciplinary, and ``multi-layered'' efforts are ongoing,
domestically and globally, ``to assure that [5G] network and [mmW]
device security is preserved to the maximum extent feasible,'' the
Commission must acknowledge that to date many wireless communications
systems have not been successful at implementing security-by-design.
The Commission recognize that, in the race to market, vital security
protections too often fall by the wayside.
151. The Commission took narrowly tailored steps to help promote an
environment that encourages the early and ongoing consideration of
security issues by all private sector participants, including
infrastructure and device firms, established communications firms, and
new entrants to communications markets. New mmW-based networks will
enable valuable new services, and accelerating the deployment of those
services is a national priority. Those benefits, however, will be
undermined if security risks are not managed by licensees. Accordingly,
the Commission is moving expeditiously both to meet the need for new
mmW spectrum for next generation services and to help ensure that
security for these services is built in from the beginning, not left as
an afterthought. In this approach, the Commission concurs with
stakeholders who identify that there is an opportunity to take action
now--before the technology is mature or the services deployed--to
encourage, from the outset, the development of necessary cybersecurity
protections alongside the development of emerging services and
technologies.
152. In the NPRM, the Commission recognized the significance of
security to 5G networks and the future devices enabled by and
connecting to them. Because of the implications related to both sets of
issues, the Commission sought comment on how to secure mmW band
devices, networks, and their communications, and specifically on ``how
to ensure that effective security features are built into key design
principles for all mmW band communications devices and networks.'' The
Commission expressed a belief in the value of ``security-by-design''
that is motivated by the Commission's expectations that these networks
may provide capabilities for a wide variety of new devices and
applications, including, among others, traditional mobile
communications capabilities, IoT and other applications as well as
devices critical to public safety and related services that provide
essential protections to the nation. The Commission indicated that
security by design means ensuring that the goals that drive the
development of networks and devices include achieving an objective
state of security. In that context, the Commission explained that the
security constructs of confidentiality, integrity, and availability
help us gain insight into security generally, and that security-by-
design can help ensure that the next generation of wireless networks
meets these critical components of a secure network. Several commenters
expressed their support for this approach.
153. The Commission continues to believe in the significant
benefits of security by design, including the benefits that the
Commission would expect to flow from using the confidentiality,
integrity, and availability construct for assessing, planning and
incorporating security elements into networks and devices as early as
possible in their developmental

[[Page 79917]]

stages. Indeed, the record demonstrates that security elements are
appropriate and important for service providers and equipment
developers to consider now, during the development process, as well as
part of an ongoing discussion as networks and devices are deployed and
operated.
154. For example, one commenter notes that the ``network-based hop-
to-hop security approach used to secure the path between communications
users will not be sufficient for differentiated end-to-end security for
certain 5G services.'' Systems are in need of a ``secure architecture,
stringent identity management and data protection, more rigorous
authentication methods, and an array of system-level protections to
defend against distributed denial of service . . . attacks and other
intrusions.'' Accordingly, the commenter believes that security
features that are incorporated into 5G systems by design would provide
a significant advantage over any ``built on top of'' system design.
Since the service and network architecture of 5G is going through
dramatic remodeling, the commenter maintains it will ``improve the
feature and competitive strength for 5G if security protection is
included at an early stage.''
155. The view that security should be a fundamental component in
the design of any new network architecture and protocols is also shared
by 5G Americas, which underscores the heightened sense that security is
expected to take on as new technology and services are deployed. For
example, 5G Americas states that 5G systems are expected to provide
important applications such as ``smart grids, telemedicine, industrial
control, public safety and automotive, [which] have security
requirements to defend against intrusion and to ensure uninterrupted
operations.'' Other commenters offer additional examples illustrating
why it is appropriate and important to build security elements into
considerations that go into developing networks and devices. For
instance, AT&T notes a variety of developments that will have security
implications: ``machine to machine communications will contemplate
energy optimization, reduced signaling, and massive connectivity. With
these advancements, IoT [Internet of Things] will become a reality. 5G
systems will be capable of supporting a range of machine-to-machine
services, from connected cars to smart cities to telemedicine and
beyond.'' Highly secure 5G systems will be expected even in times of
stress. As FiberTower notes, ``reliance on 5G will only increase in the
event of a man-made or naturally occurring outage in a critical
service.'' To support these needs, the Commission believes 5G services
will need to be highly secure prior to deployment, and the Commission
thinks it reasonable that the Commission be apprised of security plans
in place prior to 5G services becoming operational.
156. Based on the Commission's analysis of the record, the
Commission can best facilitate adoption of security-by-design
approaches by promoting an open dialogue about security practices that
would be consistent with a discussion at a standards organization.
Therefore, the Commission is asking to receive from licensees--before
they begin operations--general statements, at a level consistent with
the open forum standards body discussions, of their plans for
safeguarding their networks and devices from security breaches.
Requiring licensees to submit that information at that juncture creates
an incentive for them to engage in the development of security measures
at an earlier stage. The specific information that the Commission
receives will also facilitate the Commission's ability to help in
identifying security risks, including areas where more attention to
security may be needed, and in disseminating information about
successful practices for addressing the risks. Moreover, this approach
avoids the drawbacks of imposing prescriptive security mandates--e.g.,
downsides such as the likelihood that one size will not fit all, the
lack of agility in responding to changing circumstances and
technologies, and the rigidity that such mandates tend to introduce
into systems at the outset--thereby preserving for operators, equipment
developers, and other interested parties significant flexibilities for
addressing security concerns.
157. As described in detail below, the provision that the
Commission adopted promotes ``security-by-design'' approaches within
the mmW network and product development environment, in ways that
should (i) minimally impact (but appropriately enhance the prospects
for security ``assurance'') ongoing design and development with respect
to this nascent technology, (ii) facilitate integration of network and
product development with the timeline for standards development, and
(iii) encourage early participation in and monitoring of such standards
development. This provision--a requirement that each licensee discuss
at a high level how confidentiality, integrity, and availability
principles are reflected in its network security design planning in a
Statement submitted to the Commission prior to commencing operations--
should also help inform the Commission's collective understanding and
strategies for addressing security issues in the next generation of
communications networks. More specifically, the Commission is requiring
licensees to file a Statement with the Commission within three years
after grant of the license, but no later than six months prior to
deployment. This time period accords with the Commission's security-by-
design goals while leaving flexibility for licensees depending on when
they are able to deploy service. The Statement must be signed by a
senior executive within the licensee's organization with personal
knowledge of the organization's security plans and practices, within
the licensee's organization, and must include, at a minimum, the
following elements:
A high-level, general description of the licensee's
security approach designed to safeguard the planned network's
confidentiality, integrity, and availability with respect to
communications from: a device to the licensee's network; one element of
the licensee's network to another element on the licensee's network;
the licensee's network to another network; and device to device (with
respect to telephone voice and messaging services).
A high-level, general description of the licensee's
anticipated approach to assessing and mitigating cyber risk induced by
the presence of multiple participants in the band. This should include
the high level approach taken toward ensuring consumer network
confidentiality, integrity, and availability security principles, which
are to be protected in each of the following use cases: communications
between a wireless device and the licensee's network; communications
within and between each licensee's network; communications between
mobile devices that are under end-to-end control of the licensee; and
communications between mobile devices that are not under the end-to-end
control of the licensee.
A high-level description of cybersecurity standards and
practices to be employed, whether industry-recognized or related to
some other identifiable approach;
A description of the extent to which the licensee
participates in standards bodies or industry-led organizations pursuing
the development or maintenance of emerging security standards and/or
best practices;
The high-level identification of any other approaches to
security, unique to the services and devices the licensee intends to
offer and deploy; and

[[Page 79918]]

Plans to incorporate relevant outputs from Information
Sharing and Analysis Organizations (ISAOs) as elements of the
licensee's security architecture. Plans should include comment on
machine-to-machine threat information sharing, and any use of
anticipated standards for ISAO-based information sharing.
158. The intent of the disclosures is to facilitate multi-
stakeholder peer review and earlier development of devices and a
commercially viable market for the service. The Commission recognizes
that the Statements concern the cybersecurity of the Commission's
nation's critical communications infrastructure and, accordingly, the
content of the Statements should be at a high-level and not include
information that, if publicly disclosed, would create a significant
risk to the security of this infrastructure or related systems and
networks. The Commission also recognizes that an entity's cybersecurity
posture can be a competitive differentiator and that unauthorized
disclosures of Statements containing more detailed information could
result in competitive harm to the licensee. Here again, the Commission
concludes that the Statements should not provide information at a level
of granularity that its public disclosure would jeopardize the
competitive position of the licensee. For example, the Commission
expects that these disclosures will contain information that could be
disclosed at a standards meeting where stakeholders gather to share
ideas and information for the purpose of advancing the state of the
art. If, however, licensees intend to submit information that warrant
confidential treatment, they may seek confidential treatment pursuant
to the Commission's rules. Furthermore, the information required to be
submitted under this rule as it relates to security plans and practices
will not be used for the purpose of enforcing compliance with the
Communications Act or any of the Commission's rules, other than the
requirement of filing such Statements.
159. The Commission finds that appropriate cybersecurity safeguards
are a fundamental part of the development and deployment of mmW systems
and services contemplated by this Report and Order. The reporting
requirement the Commission adopted will not only help ensure that
industry focuses the necessary degree of attention throughout these
development and deployment processes on the most effective ways to
include these safeguards at the earlier possible points, but it will
also keep the Commission informed of the ongoing progress in this area
so the Commission can provide timely, measured and effective responses
to address any emerging problems before they become intractable. It
will also be important to consider how best to ensure that the types of
cyber safeguards that the Commission encourages for the mmW bands will
be incorporated more broadly into future so called 5G networks and
services. Consequently, the Commission directs the OET, the Public
Safety and Homeland Security Bureau (PSHSB), and the WTB to, by not
later than October 31, 2016, issue in a separate docket a Notice of
Inquiry (NOI) exploring the security implications and solutions in
future 5G networks, beyond the actions the Commission took in this
Report and Order. The Commission believes this NOI is an opportunity to
look holistically at the potential security implications in future 5G
networks offering different types of services to different types of
users (e.g., wireless broadband, low-data-rate IoT applications, high-
data-rate IoT applications). It will also provide a collaborative
vehicle for exploring 5G security-related threats, solutions, and best
practices in order to address the implications more effectively. The
NOI is not intended to duplicate or replace ongoing or future 5G
security architecture and 5G design work by standards bodies, industry
or academic groups, but instead to facilitate common appreciation
across the 5G ecosystem for the evolving security standards. The NOI
will also provide an opportunity for stakeholders to identify new 5G
issues as new IoT functions are developed in 5G, and as national
security, public safety, critical infrastructure industries, and
consumers begin to understand the implications and potential
opportunities of 5G.

G. Technical Rules

1. Flexible Duplexing Rules
160. Consistent with the Commission's proposal in the NPRM, the
Commission adopted flexible duplexing rules for the 27.5-28.35 GHz, 37-
38.6 GHz, and 38.6-40 GHz bands. While the comments indicate that TDD
is the duplexing scheme licensees are most likely to deploy in the
bands, the Commission sees no reason to prevent them from using other
technologies. Therefore, the rules the Commission adopted will allow
any type of duplexing to be deployed, subject to other technical rules
to manage interference. The Commission also adopted changes to the 39
GHz channel plan, as discussed in more detail in Section I.B.5 (39 GHz
Band (38.6-40 GHz)), which will accommodate more flexible duplexing
schemes.
2. Transmission Power Limits and Antenna Height
a. Base Stations
161. The Commission believes that an increase in the maximum base
station power from what the NPRM proposed is necessary for two reasons.
First, the 62 dBm/100 MHz EIRP power limit proposed in the NPRM will
limit UMFUS base stations to a much lower power density than is
permitted for other mobile services. For example, Personal
Communications Service (PCS) and AWS base stations are permitted to
transmit at 62 dBm/MHz EIRP, which would permit a total EIRP of 82 dBm
for a 100 MHz signal. The Commission sees no reason why UMFUS should be
limited to a lower power density than PCS and AWS. Second, the
propagation properties in the mmW band make higher powers necessary.
Signal attenuation with distance is higher in the mmW bands than at
lower frequencies and signals are more severely attenuated due to
obstacles such as foliage and walls. As the simulations submitted by
commenters illustrate, higher signal powers are necessary to permit
relatively modest base station coverage areas and to increase data
throughput. Unnecessarily limiting the base station power in the mmW
bands by applying the existing part 27 base station limit could unduly
inhibit future technologies and applications.
162. The Commission adopted a base station power limit of 75 dBm/
100 MHz EIRP as the base station power limit for the 28 GHz, the 37 GHz
and 39 GHz bands. For channel bandwidths less than 100 megahertz the
permitted EIRP will be reduced below 75 dBm proportionally and linearly
based on the bandwidth relative to 100 megahertz. Because the
technology for providing mobile services in these bands is still being
developed, the appropriate transmitted power requirements for this
equipment cannot be definitively known at this time. This 75 dBm/100
MHz limit represents a consensus that has been endorsed by the
commenters who have expressed an intention to manufacture UMFUS
equipment. Therefore, the Commission is confident that this power level
will provide the equipment manufacturers and future licensees with the
flexibility needed to deploy service in these bands. Because of the
early stage of development of UMFUS technology, the Commission will
monitor how this technology develops and revisit the base station

[[Page 79919]]

power limit in the future if it becomes necessary.
163. The Commission is not persuaded by those commenters who do not
favor increasing the base stations power limit above the level proposed
in the NPRM. Boeing's claim that the 75 dBm limit is inconsistent with
the operational range of 5G applications is contradicted by the
simulation results that show the benefits of increasing the maximum
power beyond 62 dBm and the consensus among equipment manufacturers
that 75 dBm is a reasonable power limit for UMFUS base stations.
Furthermore, the Commission's rules for the 37.5-40.0 GHz band, about
which Boeing expresses sharing concerns, limit the FSS to gateway-type
earth station operations and prohibit the ubiquitous deployment of
satellite earth stations designed to serve individual consumers. The
Commission does not believe that the higher power limit the Commission
is adopting will significantly affect the limited gateway FSS
operations permitted in the band because the Commission is providing a
means for gateway earth stations in the band to obtain protection from
terrestrial transmissions. As for SES Americom's and Avanti's concerns,
the Commission explained in Section I.G.2.d. (Terrestrial Aggregate
Interference Concerns to FSS Satellite Receivers in 28 GHz), that the
Commission does not believe the Commission needs to take specific
action with respect to aggregate interference to satellite receivers in
the 28 GHz band at this time. The Commission therefore will not unduly
restrict the development of UMFUS by limiting the base station transmit
power.
164. The Commission will not adopt a different power limit for
equipment that is used to provide both mobile services and backhaul. As
the NPRM noted, several commenters to the NOI suggested that it might
be feasible to deploy such 5G equipment. The Commission notes that
those commenters did not address this subject in response to the NPRM
and no other commenters specifically request higher power limits for
such equipment. The Commission believes that by adopting a higher power
limit for base stations than proposed in the NPRM, the Commission is
also providing adequate power to ensure successful deployment for
combined access/backhaul equipment. In addition, the Commission will
not limit base station antenna height at this time because no
commenters address the issue. Instead, the Commission shall seek
further comment on this topic in the FNPRM.
165. Compliance with the transmit power limit shall be ascertained
with over the air measurement of EIRP of the device under test (DUT).
As Qualcomm has stated, mmW devices are being designed with an array of
multiple antennas employing dynamic beamforming and that these designs
make verification of transmitter power, EIRP, and antenna gain
challenging. In this early stage of mmW development, compliance testing
will be challenging because of lack of test equipment and/or facilities
that can accurately measure over the air EIRP of the DUT and the need
to account for the introduction of antenna arrays and beamforming. Even
so, OET has issued a number of Knowledge Database (KDB) publications
that delineate measurement procedures for testing of antenna
arrays.\10\ Moreover, OET will address the further development of mmW
measurement procedures with input from industry stakeholders and other
interested parties and issue further KDB guidance.

Engineering and Technology, Laboratory Division, Emissions Testing

Commission notes that OET has developed a substantial body of
additional guidance that is available via public notices, frequently
asked questions (FAQ's), and specific process guidance that is
compiled in our online Knowledge Database (KDB). Equipment
authorization topics that relate to new services and devices
authorized by the Commission are often addressed in the KDB. This
includes, for example, simple answers to questions, guidance on how
to file for authorization of new types of devices, and guidance on
how to conduct rule compliance testing. The staff guidance provided
in the KDB is intended to assist the public in following Commission
requirements. The guidance is not binding on the Commission and will
not preclude the Commission from making a different decision in any
matter that comes to its attention for resolution.
---------------------------------------------------------------------------

b. Mobile Stations
166. As proposed in the NPRM, the Commission adopted a 43 dBm EIRP
maximum mobile power limit in the 27.5-28.35 GHz, 37-38.6 GHz, and
38.6-40 GHz bands. The simulations and analyses by commenters indicate
that this power level will be sufficient to provide the expected range
and data rates. In addition, the power level is consistent with the
Commission's rules for part 15 devices in the 57-64 GHz band that have
been in place since 1995. The Commission is also encouraged by the
strong support for this power limit, especially from commenters who
indicate that they will manufacture equipment for these bands.
167. The Commission notes that UMFUS devices will be expected to
comply with the Commission's rules regarding radiofrequency radiation
exposure in addition to complying with the 43 dBm EIRP limit the
Commission adopted. These radiofrequency radiation exposure rules
specify more stringent exposure limits for devices that are designed to
be used within 20 centimeters of the user's body. The Commission
recognizes that such devices may have to limit their transmit power
below the 43 dBm limit to meet exposure limits.
c. Transportable Stations
168. The Commission agrees with the majority of commenters that
there is a need for an additional class of transportable stations
requiring a maximum allowable power limit higher than the 43 dBm
adopted for mobile user equipment stations. Higher power for such
devices will increase range, enable higher data rates and provide for
better coverage throughout buildings, which will allow consumers
flexibility in installation locations to provide service where needed.
These devices could be used to provide residential broadband service,
which as the simulation results provided by Nokia illustrate will
benefit from a higher transmit power than the Commission is allowing
for mobile stations. The Commission adopted a 55 dBm EIRP maximum power
limit for this for this class of equipment, which the Commission shall
refer to as transportable stations. This 55 dBm limit represents a
consensus that has been endorsed by commenters who have expressed an
intention to manufacture UMFUS equipment. The Commission notes that in
adopting this higher power limit for transportable stations that such
devices will be expected to comply with the Commission's rules
regarding radiofrequency exposure.
169. No commenter has proposed a definition of transportable
devices for purposes of the Commission's rules. However, the
terminology that most commenters have used suggests that such devices
will be stationary while operating. Therefore, the Commission shall
define a transportable device as transmitting equipment that is not
intended to be used while in motion, but rather at stationary
locations. The Commission believes this definition is appropriate
because it will exclude portable devices that are meant to be carried
by people while operating such as mobile phones or smart phones from
transmitting at the higher power level. One commenter has suggested
that these transportable devices could be built into

[[Page 79920]]

vehicles, which implies that they should be permitted to operate while
in motion. The Commission has chosen not to expand the Commission's
definition to include devices in moving vehicles because such devices
in general will not need to transmit signals that penetrate walls and
therefore will not require more power than mobile devices.
d. Terrestrial Aggregate Interference Concerns to FSS Satellite
Receivers in 28 GHz
170. The analyses, provided by commenters, leads us to conclude
that specific technical limits on UMFUS stations are not necessary at
this time to address aggregate interference. As discussed in more
detail below, the information in the record shows a wide disparity
between assumptions and illustrates that much work must be done to
accurately model mmW systems and the effects that these systems might
have on co-channel satellite receivers. As a result, the Commission
does not want to unduly restrict the development and growth of UMFUS
unless the Commission has adequate evidence that actual harm will
occur. The Commission does not believe the record demonstrates that
there is a risk of interference to satellites from aggregate
interference caused by UMFUS stations. Consequently, the Commission
will not adopt a limit on aggregate skyward interference from 28 GHz
band UMFUS stations or require that UMFUS stations employ specific
techniques to reduce skyward emissions. The Commission observes that
features such as antenna downtilt, suppression of sidelobes and
adaptive power control will occur naturally because they are inherent
characteristics of anticipated 5G technologies.
171. The analyses provided by the satellite operators are based on
very conservative assumptions and provide for a worst case scenario
regarding aggregate interference from future terrestrial networks. For
example, the satellite analyses appear to assume terrestrial devices
will continuously operate at maximum power levels and do not account
for the fact that many UMFUS deployments will occur indoors. Most of
the satellite analyses assume all terrestrial devices will be line of
sight to the satellites with the exception of the analysis submitted
jointly by the Satellite Operators, which assumes only a 9.6 dB
attenuation for a 90% non-line of sight scenario. These analyses also
assume a -12.2 dB interference criteria, which the Joint Filers point
out has been under past review in language reflected in a Conference
Preparatory Meeting report to WRC-15. The Joint Filers also note that
some system parameters provided by Satellite Industry Association
(SIA), such as satellite noise and receive beam gain, are based on the
most sensitive projections about future, planned satellite network
deployments, not necessarily satellite networks that currently exist.
172. While the Joint Filer's simulation results are not based on as
conservative assumptions as the satellite operators, they vividly
illustrate how the assumptions made can lead to vastly different
conclusions. Assumptions such as the antenna pattern of the UMFUS
devices, how many of the devices are line of sight to the satellites,
the characteristics of the satellites, and the satellite interference
criteria clearly can make an enormous difference in the number of
devices that may transmit without interference occurring. Given that
mmW technology is just being developed and the deployment scenarios of
these devices are uncertain, many of these assumptions are speculative
at this point and any conclusions that can be drawn from analyses or
simulations at this point are necessarily tentative. The Commission
also observes that no information has been submitted into the record as
to how terrestrial licensees would demonstrate compliance with a limit
on aggregate energy at each satellite or each point in the sky. While
the Commission concludes that the various studies submitted by the
parties do not support establishment of an aggregate interference limit
or adoption of specific technical requirements to reduce skyward
emissions, they do indicate the need for additional study on the effect
of aggregate interference on satellite receivers. The Commission
expects that the parties will continue to study this issue and inform
the Commission of the outcome. The Commission will revisit this issue
if additional information comes to the Commission's attention
suggesting that regulatory requirements are necessary.
3. Out-of-Band Emission Limits
a. Use of Conductive Emission Limits
173. One of the implications of requiring an EIRP metric for the
OOBE limit is that a transmitter has to meet the limit along the
maximum EIRP direction. This makes meeting the radiative OOBE limit
particularly challenging, as recognized by the commenters. In the mmW
band, transmitters require higher gain antennas to compensate for
significantly higher propagation losses and consequently the antennas
will, in general, have much smaller beamwidth, as compared to other
lower band mobile systems. As a result, OOBE of mmW transmitters have
highly directive characteristics, concentrating the transmission power
along a narrow beam in the direction of maximum EIRP. Furthermore,
because the beam is narrow and because a transmitter needs to track the
relative movement of its intended receiver in order to maintain the
communication link, the OOBE of the mmW transmitter should be spatially
averaged over the path of the receiver to reflect the spatially
transient nature of the transmitter OOBE. In this regard, Qualcomm
states that, ``based on its simulations to date, the average
interference from a mobile and a base-station/small cell with a
steerable/selectable array is very different and variable when compared
to a fixed link. With mobile operations, the interference impact
differs from fixed links due to the dynamic nature of the array, for it
points in different directions as mobile users move and are served.''
The Commission believes these features of the mmW spectrum make the
OOBE limit in the maximum EIRP direction less significant and a
spatially averaged OOBE limit more appropriate. One way to spatially
average OOBE of a transmitter is to determine its out of band TRP or by
extension of its out of band conductive power.\11\ To set forth a more
suitable OOBE metric that reflects the aforementioned features of mmW
band, the Commission should express the OOBE limit as an equivalent
conductive limit. An equivalent conductive limit is consistent with the
OOBE rule for other mobile systems.
---------------------------------------------------------------------------

\11\ TRP of a transmitter is closely related to its' conductive
power. In fact, TRP is product of antenna radiation efficiency,
er, and conductive power P (TRP =erP and
depending on antenna efficiency TRP can be virtually the same as the
conductive power P. See W.L. Stutzman and Gary A. Thiele, Antenna
Theory and Design, 2013, equations 13-40 and 2-155.
---------------------------------------------------------------------------

174. Compliance with a conductive OOBE limit in the mobile mmW
systems will be the same as other mobile systems where access to the
antenna RF port(s) is available. Where access to the RF port(s) is not
available, a somewhat more complicated process is necessary. For each
frequency (or band), an emission measurement of the DUT must be
performed along the direction of the maximum EIRP. The EIRP measurement
value is then adjusted for the antenna gain along the same direction as
the measured EIRP and at the same frequency (or band) to obtain a
conductive OOBE power of the device. This process needs to be performed
for

[[Page 79921]]

both polarization and, the respective conductive OOBE power summed, to
obtain the total conductive OOBE power of the device. To obtain the
antenna gain, licenses should use a validated antenna pattern
computation, manufacturer supplied antenna pattern, or any other
approach acceptable to the Commission as may be described in OET's KDB
publications. The Commission recognizes that under certain
circumstances the DUT antenna may interact with its supporting
structure sufficiently enough that the interaction may require
consideration through simulation or by an additional measurement step.
One way to identify such circumstances may be through the antenna
pattern validation step. Other means of identifying and considering
such circumstances may be described in OET's KDB publications.
175. With respect to TRP, TRP measurement requires EIRP measurement
of the device under test around spherical surface of the device for
both polarizations, and as a result it can be time consuming and
difficult. A reverberation chamber is deemed to be one of the most
practical means of TRP measurement. However, as noted by Straight Path,
TRP measurement in a reverberation chamber requires conducted power
measurement of power amplifiers. Straight Path further argues that
given that in many cases 5G transceiver power amplifiers and antennas
may be integrated on a single printed circuit board, it is unclear how
conducted measurement can be achieved for transceivers. Moreover, even
if access to RF ports were to be made available, a conductive
measurement would be far easier and economical to perform than TRP, as
no over the air measurement would be required for conductive
measurement. However, given that a number of commenters have requested
TRP as a metric for OOBE, and given that TRP is a spatial averaging
method, the Commission will allow TRP as the alternate metric for
compliance. As there are no TRP measurement procedures currently
defined, new measurement procedures will be developed through the FCC
Laboratory's KDB process.
176. In the NPRM the Commission proposed a radiated OOBE limit that
requires licensees to attenuate their unwanted radiated emission power
below the transmission power (P) by a factor of at least 43 +
10log10(P) per MHz (or an absolute power of -13 dBm/MHz) for
any emissions on frequencies outside the licensee's authorized
spectrum. This radiated OOBE limit is consistent with the conductive
OOBE limit that the Commission has generally required for other mobile
systems. In addition, a number of commenters state that using TRP as a
metric the proposed OOBE attenuation factor or absolute power of -
13dBm/MHz would be feasible. For these reasons the Commission has set
the OOBE limit for both conductive metric and TRP metric to -13 dBm/
MHz. This may be used as a basis for developing further requirements
that relate to transmitter performance by industry standard
organizations. This limit applies to base stations, transportable, and
mobile stations.
177. With respect to dBr radiated emission mask, the mask is
significantly more relaxed than the -13 dBm/MHz absolute limit that a
number of commenters support. In addition, the Commission finds that
the equivalent conductive limit (or alternatively TRP) is the
appropriate metric for OOBE in this band. For these reasons, the
Commission declines to adopt the dBr radiated emission mask that
Qualcomm proposes.
b. Licensed Block Edge Region
178. The Commission agrees with Ericsson, and some of the other
commenters that a bandwidth-dependent unwanted emission requirement at
the first megahertz adjacent to the licensed block discriminates
against broadband systems. However, a bandwidth-independent unwanted
emission requirement at the channel edge may not be sufficient for very
large bandwidth channels, or may not be spectrally efficient for
narrowband channels. As it is difficult at this nascent stage of mmW
development to anticipate the future channel configuration of this
technology, the Commission is relaxing the emission requirement at the
channel edge dependent on channel bandwidth, so as to provide for the
greatest latitude for channel configuration. For the first 10 percent
of the channel bandwidth from the edge of the licensed block, the
Commission requires an emission level of -5 dBm/MHz. Beyond the first
10 percent of the channel bandwidth, the Commission requires an
emission level of -13 dBm/MHz. These requirements exceed Intel's
request over the first 10 percent of the channel bandwidth immediately
outside and adjacent to the licensee's frequency block. The permissible
out of band power under these emission limits are higher than Nokia and
Sprint recommendations over the first 10 percent of the channel
bandwidth, but lower than Samsung's recommendations. Overall, the
Commission believes these requirements balance the various comments on
record.
4. Interference Protection and Coordination
a. Coordination and Field Strength Limits at Market Borders
i Base/Mobile Operations
179. The Commission agrees with the majority of commenters that
some criteria is necessary at market boundaries to manage interference
and coordination between adjacent area licensees. The Commission also
believes that given the wide channel bandwidths and diversity of
potential applications that might be deployed in these bands, any
criteria that the Commission adopts should include a scaling factor for
the bandwidth. Therefore, the Commission will adopt a PFD limit/MHz
that base operations must meet at the licensee's market boundary,
absent a mutual agreement between adjacent market licensees to exceed
that value.
180. The Commission continues to believe that the 47dBuV/m field
strength value that the Commission proposed in the NPRM is an
appropriate basis on which to set a PFD limit for the mmW bands. This
is the same limit that has been successfully used in the PCS, AWS, and
BRS bands. However, the Commission notes that a field strength of
47dBuV/m results in a very conservative absolute power limit because
field strength does not take into consideration the bandwidth and
frequency components. Therefore, the Commission believes it is
appropriate to convert a 47dBuV/m field strength to a PFD limit in
terms of dBm/m\2\/MHz for the mmW bands. Looking again at the AWS, PCS,
and BRS bands, the Commission notes that the equivalent PFD based on a
47dBuV/m field strength is within the range of -76 to -81 dBm/m\2\/MHz
depending on what bandwidth is assumed. The Commission observes that
these values bound the -77.6 dBm/m\2\/MHz PFD limit proposed by the
joint filers. The Commission also recognizes that these values are
higher than the -86 dBm/m\2\/MHz PFD proposed by Straight Path and the
-90.3 dBm/m\2\/MHz PFD proposed by Intel. However, the Commission notes
that Straight Path assumed an interference criteria of -10 dB I/N. In
recent rulemakings the Commission has assumed an interference criteria
of 0 dB I/N. Adjusting Straight Path's proposed limit to provide a 0dB
I/N as opposed to a -10dB I/N yields a market boundary limit of -76
dBm/m\2\/MHz. The Commission also notes that Intel's

[[Page 79922]]

proposed PFD was based on worst case assumptions about the receive
antenna gain, citing that the base station would have a gain of 29.1 dB
in the direction of the interfering source. The Commission believes
that this assumption is overly conservative. For example, the joint
filers stated that a lower antenna gain is typically computed in the
simulation towards the earth station since the receive beam is pointed
in the direction of the transmitting UE, and it is statistically
unlikely to coincide with the direction towards the earth station.
Thus, on balance, the Commission believes that adopting a -77.6 dBm/
m\2\/MHz PFD limit as suggested by the joint filers, will protect
terrestrial facilities in adjacent market areas from interference in a
variety of different terrestrial to terrestrial use cases as well as
the earth station to terrestrial scenario. Therefore, the Commission
will adopt a market border PFD limit of -77.6 dBm/m\2\/MHz measured at
1.5 meters above ground. The Commission emphasizes that this level is
intended to be a coordination trigger and that adjacent licensees are
free to coordinate mutually agreed upon limits that exceed this value
along their common market boundaries. The Commission will also reserve
the right to revisit the market border PFD limit in the future if it
becomes necessary as technology and services develop in these bands.
ii. Fixed Point-to-Point Operations
181. The Commission agrees with Skyriver that a field strength
limit would not be appropriate for fixed point-to-point operations
because it would require large power reductions by fixed service
providers. The Commission will retain the existing part 101 technical
rules for traditional fixed point-to-point links. As such, the
Commission believes that it is also appropriate to retain the existing
requirement that fixed point-to-point operations within 16 kilometers
(in the 38.6-40 GHz band) or 20 kilometers (in the 27.5-28.35 GHz band)
of a licensee's market boundary must coordinate with co-channel
licensees in adjacent market areas. With respect to Sprint's suggestion
that the Commission impose a coordination requirement for adjacent
channel licensees; in light of the OOBE limits that the Commission
adopted, the Commission does not believe that any additional
coordination requirement is necessary for adjacent channel
operation.\12\ The Commission seeks comment on further refining these
coordination requirements in the FNPRM.
---------------------------------------------------------------------------

\12\ The Commission also notes that Sprint's assumption that ULS
contains current station information is not entirely correct. While
ULS does contain some information on leased links there is no
requirement for licensees to report all fixed point-to-point links
operating under their geographic licenses. Therefore the ULS
database is an incomplete record of the existing point-to-point
links.
---------------------------------------------------------------------------

b. Canadian and Mexican Borders
182. In the NPRM, the Commission proposed to adopt a rule for the
27.5-28.35 GHz, 37-38.6 GHz, and 38.6-40 GHz bands similar to Sec.
101.147(r)(13), 101.509(d), or 27.57 of the Commission's rules which
provide that fixed and mobile operations are subject to existing and
future international agreements with Mexico and Canada. The Commission
noted that there are existing arrangements for fixed operations in the
27.5-28.35 GHz and 38.6-40.0 GHz bands between the United States and
Canada. The Commission also noted that mmW operations must not cause
harmful interference across any of the Commission's international
borders. No parties filed comments with respect to this proposal.
183. Consistent with the Commission's rules for other services, the
Commission adopted a rule that the 27.5-28.35 GHz, 37-38.6 GHz, and
38.6-40 GHz bands are subject to existing and future agreements with
Mexico and Canada.
5. Operability
184. The Commission adopted its proposal to require operability
across each millimeter wave band for mobile and transportable
equipment. The Commission continues believe that interoperability
delivers important benefits to consumers. While there is significant
opposition in the record to an interoperability requirement, no
commenter offered specific reasons why the type of operability proposed
in the NPRM would be either technically infeasible or harmful as a
policy matter in these bands. In addition, much of the opposition in
the record appears to be based on an interpretation of an
interoperability requirement that the Commission did not propose. The
Commission therefore concludes that the benefit to consumers outweighs
the burden to manufacturers in this regard.
185. Specifically, the Commission requires that any mobile or
transportable device designed to operate within the 28 GHz band (27.5
GHz-28.35 GHz) be capable of operating at all frequencies within the 28
GHz band, on each air interface it uses to operate in the 28 GHz band,
and similarly that a device operating in the 37 or 39 GHz bands be
capable of operating at all frequencies within those bands (37 GHz-40
GHz). For example, a device that uses an LTE air interface to operate
in a lower frequency band, and a future 5G air interface to operate in
the 28 GHz band, would be compliant with this requirement if it could
operate on frequencies from 27.5 GHz to 28.35 GHz using the 5G air
interface.
186. For the purposes of this requirement, for the 37 GHz and 39
GHz bands, a device operating in either band must be capable of
operating across the entirety of both bands, from 37 GHz to 40 GHz
(including the 37-37.6 MHz lower block). This requirement will increase
the market for equipment in these bands, and allow both smaller and
larger service providers to benefit from economies of scale and
increased equipment availability. Mandating operability will also
facilitate shared use of the 37 GHz band by ensuring that a wide
variety of equipment is available by both Federal agencies and non-
Federal SALs.
187. The Commission emphasizes that it will not mandate
compatibility of each device with all possible air interfaces to be
used in these bands, as some commenters interpreted. Rather, the
Commission will mandate that with each air interface used by a
particular device in a millimeter wave band, that device must be
capable of operating across the entire band. The Commission does not
adopt any requirement that a device must be capable of utilizing any
particular standard, technology, or air interface. Additionally, while
the Commission does not require operability of base or fixed equipment,
it is its expectation that licensees will work in good faith through
the standards setting process to develop standards, as technically
feasible, that support the operation of base and fixed equipment across
each band.
6. Technical Rules for Part 15 Operation Within the 64-71 GHz Band
188. The Commission is adopting requirements for unlicensed
operations in the 64-71 GHz band that are based on the technical
standards used for the 57-64 GHz band under Sec. 15.255 of the
Commission's rules. Part 15 of the Commission's regulations permits the
operation of radio frequency (RF) devices without an individual license
from the Commission or the need for frequency coordination. The
technical standards contained in part 15 are designed to ensure that
there is a low probability that such devices will cause harmful
interference to other users of the radio spectrum. Except for operating

[[Page 79923]]

on-board aircraft or satellites, and in mobile field disturbance sensor
applications, any type of unlicensed operation is permitted within the
57-64 GHz band under Sec. 15.255 of the Commission's rules.\13\
---------------------------------------------------------------------------

\13\ A field disturbance sensor is defined as ``a device that
establishes a radio frequency field in its vicinity and detects
changes in that field resulting from the movement of persons or
objects within its range.'' 47 CFR 15.3(l). Examples of unlicensed
field disturbance sensors include radars operating under 47 CFR
15.252 or 15.256; and perimeter protection systems operating under
47 CFR 15.209(g) or 15.229.
---------------------------------------------------------------------------

189. Suitability of the Existing Rules in Section 15.255 to the 64-
71 GHz Band. In the NPRM, the Commission proposed to apply the existing
rules in Sec. 15.255 to the 64-71 GHz band with some adjustments, and
sought comments on certain aspects of the rules to further the growth
and development of devices without increasing the potential for harmful
interference to authorized users in the bands. Proponents of unlicensed
operations unanimously support the proposal to extend the technical
rules in Sec. 15.255 to cover the entire 57-71 GHz band. Google argues
that harmonized rules for the frequencies between 57 and 71 GHz will
allow economies of scale and other efficiencies, thereby facilitating
rapid and widespread deployment of unlicensed devices; the Wi-Fi
Alliance confirms that extending part 15 rules to the 64-71 GHz band
would greatly enhance the capacity of next-generation WiGig
technologies.'' The Commission finds that the existing technical rules
in the 57-64 GHz band can successfully apply to the proposed 64-71 GHz
adjacent band, with certain adjustments, as the Commission examines the
pertinent rules in detail below.
a. Operation On-Board Aircraft
190. The Commission is reluctant to allow 60 GHz unlicensed
operations on-board aircraft in the 57-71 GHz band at the present time.
In the NPRM, the Commission did not propose to permit unlicensed
operations on-board aircraft but sought to start the discussion to
compile a comprehensive record on this subject. The Commission noted,
there are substantial technical disagreements between the passive
services licensees and the WiGig industry regarding the attenuation
provided by aircraft components (e.g., windows and fuselage) and how
WiGig signals would propagate (e.g., by direct line-of-sight or
reflections, etc.) and aggregate. The Commission further observes that
even among the WiGig industry advocates, there is technical
disagreement. For example, ZII, a wireless inflight entertainment
services and products provider, opposes on-board aircraft operation of
WiGig devices in the 64-71 GHz band at the present time due to its
findings of potential harmful interference to passive services above 63
GHz despite its financial interest in providing these services.
Conversely, the Wi-Fi Alliance's analysis found no harmful interference
to EESS and RAS in the entire 57-71 GHz spectrum. The Commission also
finds that the studies and technical analyses submitted in the record
are not persuasive for several reasons. First, the CEPT ECC and ITU
reports do not address the 60 GHz band, but cover lower frequencies.
Second, the various link budget analyses from the industry (e.g., from
ZII and Wi-Fi Alliance) do not show a technical consensus, at least for
a portion of the proposed 57-71 GHz band, and cast doubt on the
validity of certain assumptions used to derive these link budgets.
Third, since the collaboration effort between the WiGig industry and
NTIA/NSF/JPL (Jet Propulsion Laboratory) has not yet resolved many
issues, as indicated by NRAO, a decision on the Commission's part at
this time could prejudge the outcome of that work. Finally, the
Commission notes that 60 GHz transmitters in mobile devices are only
just beginning to be marketed, and the impact of their deployment in
real-world scenarios will require time to be assessed adequately.
Further, the technology will continue to evolve to address signal
propagation challenges in the mmW spectrum such that analyses of WiGig
transmissions on-board aircraft could change substantially once the
Commission has wide deployments.
191. The Commission finds that further technical analyses and data
are necessary before lifting the present operation restriction because
the record so far did not reflect a clear perspective of the types of
WiGig applications envisioned on-board aircraft, the priority/order of
their planned introduction, etc., to provide an adequate assessment of
their associated potential harmful interference profile as the
Commission elaborates further in the FNPRM to seek additional
information on this topic, infra. Specifically, the Commission requests
sharing studies and data demonstrating that 60 GHz transmitters could
operate on-board aircraft without causing harmful interference to
passive sensor services in various types of inflight applications and
on various types of aircraft.
192. Finally, the Commission finds that as long as the Commission
does not permit 60 GHz operations on-board aircraft, the airlines (who
control the aircraft) would not install access points operating at 60
GHz on airplanes to provide entertainment/broadband services to WiGig
user devices. Without the presence of 60 GHz access points, the
potential for widespread airborne WiGig transmissions is removed. The
Commission also expects manufacturers/host integrators of WiGig
transmitters that are incorporated into mobile devices, such as
laptops, to provide instructions to end users regarding the prohibition
of operating such transmitters' on-board aircraft, in compliance with
the Commission's rules as part of the equipment authorization process.
Consequently, end users will be aware of this rule to avoid device-to-
device transmissions. Based on the above, the Commission is extending
the restriction on on-board aircraft operation in Sec. 15.255(a)(1) to
cover the entire 57-71 GHz band.
b. Field Disturbance Sensor Operation
193. The Commission is reluctant at this time to lift the
restriction on mobile field disturbance applications in the 60 GHz
spectrum. At this time, the Commission does not have sufficient
information about the operation of these mobile field disturbance
sensors in this spectrum to allow general operation of all mobile field
disturbance sensors. However, the Commission finds that the narrow
application of mobile radars in short-range devices for interactive
motion sensing, such as that described in Google's Project Soli,--where
a radar is used to detect hand gestures very close to a device to
control the device without touching it--could be allowed without
causing harmful interference to other authorized users. As a first
cautious step, the Commission will not permit these devices to operate
at the same power levels as 60 GHz communications devices in this
spectrum, as Google requests, but will allow these short-range devices
to operate at the same low power levels as those permitted in existing
fixed field disturbance sensors (i.e., 10 dBm peak EIRP and -10 dBm
peak transmitter conducted output power, approximately 30 dB below the
allowable power levels of WiGig communications devices). These power
levels will ensure that the mobile radars will operate at very short
distances--such as using hand gestures to control a watch, a
smartphone's or tablet's screen--which will minimize their harmful
interference potential. As the Commission acquires more experience with
these devices, the Commission may consider allowing them higher power
levels in the future. Accordingly, the Commission is

[[Page 79924]]

amending Sec. 15.255 to permit the operation of short-range devices
for interactive motion sensing at 10 dBm peak EIRP and -10 dBm peak
transmitter conducted output power over the entire 57-71 GHz band.
194. With respect to fixed field disturbance sensors, the
Commission finds that these devices can continue to operate under the
technical rules in Sec. 15.255, as they have successfully done over
the years, and that these rules may be extended to the 64-71 GHz band
without increasing the potential for harmful interference to
communication devices in the band. This would result in their wider
usage in wireless factory automation processes in manufacturing
facilities, such as those mentioned by Boeing. Accordingly, the
Commission is amending Sec. 15.255 to allow the operation of fixed
field disturbance sensors over the entire 57-71 GHz band at the
existing power limits permitted in the 57-64 GHz band (i.e., 10 dBm
peak EIRP and -10 dBm peak transmitter conducted output power).
c. Emission Limits
195. The Commission declines to increase the EIRP limits for low-
power networking indoor and outdoor 60 GHz transmitters by a factor of
10 as requested by commenters. The Commission notes that the existing
generous average and peak EIRP limits were adopted based on the very
high oxygen attenuation in the 57-64 GHz band, which would ensure that
unlicensed transmitters operating in this band do not cause harmful
interference to other authorized services. The Commission further notes
that the Commission proposed the same emission limits for the 64-71 GHz
band, despite the fact that this band does not exhibit the same
atmospheric attenuation characteristics, which would enable equipment
operating in the proposed 64-71 GHz band at the same emission levels to
effectively provide longer range and higher data throughput. The
Commission finds that keeping the same emission limits in the absence
of high oxygen attenuation in the 64-71 GHz band effectively provides
an increase in power. No additional increase is necessary at this time
and the Commission is amending the EIRP limits for 60 GHz transmitters
in Sec. 15.255 to apply across the 57-71 GHz band.
d. Spurious Emissions
196. The Commission observes that since the Commission first
adopted part 15 rules for unlicensed operation in the 57-64 GHz band in
the 1995-2000 time frame, 60 GHz unlicensed transmitters have been
operating without causing harmful interference to RAS by their harmonic
signals. This indicates that the Commission's spurious emission limits
in Sec. 15.255 for transmitters operating in the existing 57-64 GHz
band are adequate for protecting these passive services. Thus, the
Commission is concerned with the potential effect of the harmonics of
fundamental signals in the proposed 64-71 GHz band. The Commission
observes at the outset that the existing spurious emission limit in
Sec. 15.255, at 90 pW/cm\2\, is extremely low as compared to the
spurious limit adopted for other unlicensed transmitters operating in
comparative spectrum, such as the 76-77 GHz, which, at 600 pW/cm\2\, is
more than 6 times higher than the spurious limit in Sec. 15.255.
197. While acknowledging that attenuation effects due to oxygen
become much less pronounced in the 64-71 GHz band as compared to the
57-64 GHz band, the Commission finds that interference to RAS stations
is unlikely for the following reasons. First, RAS receivers
discriminate against off-axis signals, are generally located in rural
and remote areas, and radio astronomy observatories typically have
control over access to a distance of one kilometer from the telescopes
to provide protection from interference caused by uncontrolled radio
frequency interference (RFI) sources. Second, the severe propagation
losses of RF signals in the 64-71 GHz band, their ability to be blocked
easily by terrain and obstacles, and the typically directional
emissions of transmitters at these frequencies limit any potential for
interference from fundamental emissions to a short distance (e.g., 100-
200 meters). Third, spurious and harmonic emissions generally roll off
(i.e., reduce in amplitude) the further they are in frequency from the
fundamental emission; therefore, if fundamental emissions are severely
attenuated, harmonics would be affected proportionally. Based on all
these factors, the Commission finds that spurious and harmonic
emissions of 57-71 GHz unlicensed transmitters at the very low limit of
90 pW/cm\2\ in Sec. 15.255 would not cause harmful interference to RAS
operations. Accordingly, the Commission is amending the spurious
emission rule in Sec. 15.255 to apply across the 57-71 GHz band.
e. Publicly-Accessible Coordination Channel
198. Section 15.255(d) sets aside a publicly-accessible
coordination channel in the 57.00-57.05 GHz band, in which only
spurious emissions and emissions related to coordination techniques
regarding interference management between diverse, non-interoperable,
transmitters are permitted. The Commission observed in the NPRM that
with recent technological advances and industry standardization, co-
existence between 60 GHz devices is better resolved by voluntary
standards than by a coordination channel requirement in the rules, and
proposed to remove this requirement. Commenters unanimously agree with
the Commission's assessment and support the elimination of this
requirement to free a 50-megahertz swath of spectrum for communications
usage. Accordingly, the Commission is removing the requirement for a
publicly-accessible coordination channel from Sec. 15.255.
f. Conducted Transmitter Output Power
199. Section 15.255(e) limits the peak transmitter conducted output
power of 57-64 GHz unlicensed devices to 500 mW (i.e., 27 dBm) for
transmitters with an emission bandwidth of at least 100 MHz, and is
reduced for systems that employ narrower bandwidths.
200. The Commission declines to remove this requirement. The reason
for limiting the peak transmitter conducted output power while allowing
very high EIRP limits (in this case, 40 dBm (10W) average/43 dBm (20W)
peak) for an unlicensed transmitter is to ensure that the transmitter
antenna beamwidth is kept sufficiently narrow to avoid causing harmful
interference to other users in the band and to minimize the risk of RF
exposure to humans. Accordingly, the Commission denies NCTA's request
and amend the peak transmitter conducted output power requirement in
Sec. 15.255 to apply across the 57-71 GHz band.
g. Frequency Stability
201. Section 15.255(f) requires that fundamental emissions be
contained within the 57-64 GHz frequency band during all conditions of
operation; and that equipment be able to operate over the temperature
range -20 to +50 degrees Celsius with an input voltage variation of 85%
to 115% of rated input voltage. In the NPRM, the Commission proposed to
apply the same requirements to transmitters operating in the 64-71 GHz
band. No party objects to this proposal. Accordingly, the Commission is
amending Sec. 15.255 to apply across the 57-71 GHz band.
h. Co-Location of Separately-Authorized Transmitters
202. Section 15.255(h) allows group installation of transmitters
that have

[[Page 79925]]

been tested separately for compliance with the rules and received
separate equipment authorizations, as long as no transmitter in the
group is equipped with external phase-locking inputs that permit beam-
forming arrays to be realized. In the NPRM, the Commission indicated
that this requirement seeks to prevent the possibility of producing a
high-power coherent beam from discrete transmitters that have not been
tested for compliance together. This could lead to non-compliance with
the emission limits but it does not preclude the use of advanced
antenna technologies with beam-forming arrays in any transmitter, as
long as the emissions in any array configuration comply with the
emission and RF exposure limits. The Commission proposed to apply the
same requirement to equipment operating in the 64-71 GHz band. No party
objects to this proposal. Accordingly, the Commission is amending Sec.
15.255 to apply across the 57-71 GHz band.
7. Equipment Authorization
203. The OET was delegated authority by the Commission to
administer the equipment authorization program for RF devices under
part 2 of its rules. All RF devices subject to equipment authorization
must comply with the Commission's rules prior to importation or
marketing, by being tested for compliance with the applicable technical
requirements, using measurement procedures that either follow guidance
issued by OET through its KDB publications, or have been found to be
acceptable to the Commission in accordance with Sec. 2.947 of the
rules.
a. Measurement Techniques
204. In the NPRM, the Commission recognized that there are some
unique technical challenges specific to demonstrating compliance for
the purpose of equipment authorization of millimeter wave devices. The
Commission sought comments on a variety of challenges involved with
measurements of in-band, out-of-band and spurious emissions. As
discussed, supra, a number of parties discuss the measurement
challenges concerning emission limit metrics. For example, certain
parties oppose using EIRP as the metric for measuring OOBE limits,
proposing instead a different metric using TRP, claiming consistency
with recent academic research for multiple-input, multiple-output
(MIMO) antenna arrays. However, TRP is not presently part of the
Commission's measurement procedure guidance for devices using MIMO
antennas. Commenters recommend that the Commission continue to provide
guidance on acceptable new measurement procedures via OET's KDB
publications. Commenters also recognize that 5G technology is in the
early stages of equipment design and development so it is difficult at
this point in time to identify all of the potential compliance and
measurement challenges.
205. The Commission finds that the mmW technology will continue to
evolve to address various technical challenges in this spectrum (with
respect to propagation, interference protection, modulation techniques,
transmission security, etc.), and pending new measurement equipment
availability to cover the entire mmW spectrum that the Commission is
making available for the next generation of wireless services herein,
mmW measurement procedures are best developed by OET with the
participation of interested parties. The Commission expects that OET
will provide guidance on various acceptable measurement techniques for
mmW devices through its KDB publications as products are developed.
b. RF Exposure Compliance
206. (RF) exposure compliance is an ongoing requirement for all
transmitters authorized by the Commission. In the NPRM, the Commission
proposed to similarly require compliance with the Commission's general
RF exposure limits in Sec. Sec. 1.1307(b), 2.1091 and 2.1093 of the
rules for equipment operating in the UMFUS. While the Commission sought
comment on this proposal alongside some of the other relevant technical
challenges unique to compliance demonstration for devices envisaged to
be operating under the UMFUS, the Commission acknowledged in the NPRM
that any issues raised involving the present exposure limits themselves
would be considered in the context of the Commission's separate
proceeding on this particular issue.
207. With respect to the rules specific to UMFUS in part 30 of the
Commission's rules, the Commission adopts the paragraph the Commission
proposed in the NPRM that requires compliance with the Commission's
general RF exposure limits in Sec. Sec. 1.1307(b), 2.1091 and 2.1093
of the rules. The comments from industry advocate adopting alternative
exposure limits, which the Commission continues to view as beyond the
scope of this proceeding, and that will be considered in a separate
proceeding. The Commission is not changing its fundamental exposure
limits at this time in light of the devices to be expected under the
UMFUS rules. More specifically, the Commission is not modifying its
specified SAR values as a primary exposure limit between 100 kHz and 6
GHz, and the Commission will continue to use the specified MPE power
density limit as a primary exposure limit above 6 GHz.
208. The Commission recognizes that there is a discontinuity at 6
GHz resulting from the fact that the Commission's rules do not specify
a spatial averaging area (an area over which to average power density)
or a spatial peak power density above 6 GHz that is consistent with the
Commission's localized (over 1 gram) specific absorption rate (SAR)
below 6 GHz. At lower frequencies for sources at least 20 cm from the
body, spatial averaging over the entire body has been acceptable.
However, both IEEE and International Commission on Non-Ionizing
Radiation Protection (ICNIRP) have recognized that at higher
frequencies spatial averaging areas need to be smaller. Of these
specifications, the smaller and more conservative area is by ICNIRP,
which has specified a spatial averaging area of 20 cm\2\ above 10 GHz.
While the Commission notes this as an apparently reasonable requirement
the Commission is not suggesting any particular changes to the
Commission's evaluation procedures at this time. The Commission will
separately consider the broader questions of the RF exposure limits and
how they should be applied in the Commission's RF Inquiry. In the
meantime, as the Commission acknowledged in the NPRM, specific guidance
on evaluating devices operating in this service will be issued by OET,
and it is consistent with the Commission's existing discussions on
spatial averaging to further clarify guidance on an area over which to
average power density in the Commission's KDB publications through that
process. Finally, the Commission acknowledges the variations between
standards pointed out by the MMF and encourage further efforts on the
specific issue of localized millimeter wave exposure by the standards
setting bodies and the broader research community.
H. Other Allocation Issues
209. The Commission deletes the broadcasting and broadcasting-
satellite service allocations from the 42 GHz band to better protect
the radio astronomy observations of the 42.5-43.5 GHz band from out-of-
band emissions. Further, the ubiquitous nature of the BSS and the
broadcasting service would likely interfere with ubiquitous mobile
deployment in similar ways to a ubiquitous fixed service deployment. As

[[Page 79926]]

previously noted, the BSS also poses an interference risk to adjacent
RAS services. Nevertheless, the BSS will still retain 1.5 gigahertz of
spectrum in the 40.5-42 GHz band for its future operations.
210. The Commission also declines to adopt its proposal to allocate
the 42 GHz band for FSS downlink operations. Given the Commission's
decision to grant FSS enhanced access to the 37.5-40 GHz band, and the
fact that FSS has access to the 40.5-42 GHz band, the Commission find
there is less reason to further expand FSS operations to the 42 GHz
band. The Commission believes there is value in potentially having an
UMFUS band available for exclusive terrestrial use, and the Commission
addresses this issue in the companion FNPRM.

II. Procedural Matters

Final Regulatory Flexibility Analysis

211. As required by the Regulatory Flexibility Act of 1980, as
amended (RFA), the Commission incorporated an Initial Regulatory
Flexibility Analysis (IRFA) of the possible significant economic impact
on a substantial number of small entities by the policies and rules
proposed in the NPRM. No comments were filed addressing the IRFA.
Because the Commission amends the rules in this Report and Order, the
Commission has included this Final Regulatory Flexibility Analysis
(FRFA) which conforms to the RFA.
1. Need for, and Objectives of, the Proposed Rules
212. In the attached Report and Order, the Commission increases the
Nation's supply of spectrum for mobile broadband by adopting rules for
fixed and mobile services in the 27.5-28.35 GHz band (28 GHz band), the
38.6-40 GHz band (39 GHz band), and the 37-38.6 GHz band (37 GHz band).
The Commission also authorizes unlicensed operation pursuant to part 15
of its rules in the 64-71 GHz band. These bands are known collectively
as the ``mmW bands.''
213. Until recently, the mmW bands were generally considered
unsuitable for mobile applications because of propagation losses at
such high frequencies and the inability of mmW signals to propagate
around obstacles. As increasing congestion has begun to fill the lower
bands and carriers have resorted to smaller and smaller microcells in
order to re-use the available spectrum, however, industry is taking
another look at the mmW bands and beginning to realize that at least
some of its presumed disadvantages can be turned to advantage. For
example, short transmission paths and high propagation losses can
facilitate spectrum re-use in microcellular deployments by limiting the
amount of interference between adjacent cells. Furthermore, where
longer paths are desired, the extremely short wavelengths of mmW
signals make it feasible for very small antennas to concentrate signals
into highly focused beams with enough gain to overcome propagation
losses. The short wavelengths of mmW signals also make it possible to
build multi-element, dynamic beam-forming antennas that will be small
enough to fit into handsets--a feat that might never be possible at the
lower, longer-wavelength frequencies below 6 GHz where cell phones
operate today.
214. In the 28 GHz, 39 GHz, and 37 GHz bands, the Commission
creates a new radio service in a new rule part that will authorize
fixed and mobile services--the part 30 Upper Microwave Flexible Use
Service. This additional spectrum for mobile use will help ensure that
the speed, capacity, and ubiquity of the nation's wireless networks
keeps pace with the skyrocketing demand for mobile service. It will
also make possible new types of services for consumers and businesses.
215. The service rules the Commission adopted make additional
spectrum available for flexible use. In creating service rules for
these bands, which include technical rules to protect against harmful
interference, licensing rules to establish geographic license areas and
spectrum block sizes, and performance requirements to promote robust
buildout, the Commission advances toward enabling rapid and efficient
deployment. The Commission does so by providing flexible service,
technical, assignment, and licensing rules for this spectrum, except
where special provisions are necessary to facilitate shared use with
other co-primary users.
216. For the 28 GHz 37 GHz, and 39 GHz bands, the Commission
proposes to assign licenses by competitive bidding using counties as
the area for geographic area licensing in the 28 GHz band and in a
portion of 37 GHz band (37-37.6 GHz). The Commission will award PEA-
based licenses by competitive bidding for the 39 GHz and the upper
portion of the 37 GHz band (37.6-38.6 GHz). In the 37-37.6 GHz band,
the Commission has created a 600 MHz shared access space with rule-
based, non-interfering Shared Access Licenses (SALs) which will share
the band with Federal fixed and mobile operations. SAL licensees are
not guaranteed spectrum access or interference protection from
individual licensees. The Commission believes this system at 37 GHz
will create an innovative shared space that can be used by a wide
variety of Federal and non-Federal users, by new entrants and by
established operators--and small businesses in particular--to
experiment with new technologies in the mmW space and innovate.
217. At the same time, because the 28 GHz, 39 GHz, and 37 GHz bands
are shared with satellite services, the Commission has taken steps to
facilitate sharing with satellite uses in ways that are consistent with
fixed and mobile use of the bands. Specifically, the Commission
concludes the Commission will authorize a limited number of satellite
earth stations to operate on a co-primary basis--one in each county for
the 28 GHz band and one in each PEA in the 37.5-40 GHz band--on a
first-come, first-served basis. In the 28 GHz band the Commission will
grandfather pre-existing satellite earth stations in any county into a
local interference zone with the right to operate under the terms of
their existing authorizations. These FSS earth stations must comply
with certain enumerated conditions to obtain an authorization for their
specific locations, including coordinating their operations with any
existing mmW licensees to ensure non-interference between the services.
Additional earth stations can be located if the FSS operator acquires a
part 30 license, reaches a contractual agreement with the part 30
licensee, or agrees to operate on a secondary basis.
218. Overall, the new provisions the Commission is adopting are
designed to allow licensees to choose their type of service offerings,
to encourage innovation and investment in mobile and fixed use in this
spectrum, and to provide a stable regulatory environment in which
fixed, mobile, and satellite deployment will be able to develop through
the application of flexible rules. The market-oriented licensing
framework for these bands will ensure that this spectrum is efficiently
utilized and will foster the development of new and innovative
technologies and services, as well as encourage the growth and
development of a wide variety of services, ultimately leading to
greater benefits to consumers.
2. Summary of Significant Issues Raised by Public Comments in Response
to the IRFA
219. No comments were filed in direct response to the IRFA.

[[Page 79927]]

3. Response to Comments by the Chief Counsel for Advocacy of the Small
Business Administration
220. Pursuant to the Small Business Jobs Act of 2010, which amended
the RFA, the Commission is required to respond to any comments filed by
the Chief Counsel for Advocacy of the Small Business Administration
(SBA), and to provide a detailed statement of any change made to the
proposed rules as a result of those comments. The Chief Counsel did not
file any comments in response to the proposed rules in this proceeding.
4. Description and Estimate of the Number of Small Entities to Which
the Proposed Rules Will Apply
221. The RFA directs agencies to provide a description of, and
where feasible, an estimate of the number of small entities that may be
affected by the proposed rules and policies, if adopted. The RFA
generally defines the term ``small entity'' as having the same meaning
as the terms ``small business,'' ``small organization,'' and ``small
governmental jurisdiction.'' In addition, the term ``small business''
has the same meaning as the term ``small business concern'' under the
Small Business Act. A ``small business concern'' is one which: (1) Is
independently owned and operated; (2) is not dominant in its field of
operation; and (3) satisfies any additional criteria established by the
SBA.
222. Small Businesses, Small Organizations, and Small Governmental
Jurisdictions. The Commission's action may, over time, affect small
entities that are not easily categorized at present. The Commission
therefore describes here, at the outset, three comprehensive, statutory
small entity size standards. First, nationwide, there are a total of
approximately 28.2 million businesses, 99.7 percent of which are small,
according to the SBA. In addition, a ``small organization'' is
generally ``any not-for-profit enterprise which is independently owned
and operated and is not dominant in its field.'' Nationwide, as of
2007, there were approximately 1,621,315 small organizations. Finally,
the term ``small governmental jurisdiction'' is defined generally as
``governments of cities, towns, townships, villages, school districts,
or special districts, with a population of less than fifty thousand.''
Census Bureau data for 2011 indicate that there were 89,476 local
governmental jurisdictions in the United States. The Commission
estimates that, of this total, as many as 88,506 entities may qualify
as ``small governmental jurisdictions.'' Thus, the Commission estimates
that most governmental jurisdictions are small.
223. Wireless Telecommunications Carriers (except satellite). The
appropriate size standard under SBA rules is for the category Wireless
Telecommunications Carriers. Under that size standard, such a business
is small if it has 1,500 or fewer employees. Census Bureau data for
2012, show that there were 967 firms in this category that operated for
the entire year. Of this total, 955 had employment of 999 or fewer, and
12 firms had employment of 1,000 employees or more. Thus under this
category and the associated small business size standard, the
Commission estimates that the majority of wireless telecommunications
carriers (except satellite) are small entities that may be affected by
the Commission's action.
224. Fixed Microwave Services. Microwave services include common
carrier, private-operational fixed, and broadcast auxiliary radio
services. They also include the Local Multipoint Distribution Service
(LMDS), the Digital Electronic Message Service (DEMS), the 39 GHz
Service (39 GHz), the 24 GHz Service, and the Millimeter Wave Service
where licensees can choose between common carrier and non-common
carrier status. At present, there are approximately 61,970 common
carrier fixed licensees, 62,909 private and public safety operational-
fixed licensees, 20,349 broadcast auxiliary radio licensees, 412 LMDS
licenses, 35 DEMS licenses, 870 39 GHz licenses, and five 24 GHz
licenses, and 408 Millimeter Wave licenses in the microwave services.
The Commission has not yet defined a small business with respect to
microwave services. For purposes of the FRFA, the Commission will use
the SBA's definition applicable to Wireless Telecommunications Carriers
(except satellite)--i.e., an entity with no more than 1,500 persons is
considered small. Under that size standard, such a business is small if
it has 1,500 or fewer employees. Census Bureau data for 2012, show that
there were 967 firms in this category that operated for the entire
year. Of this total, 955 had employment of 999 or fewer, and 12 firms
had employment of 1,000 employees or more. Thus under this category and
the associated small business size standard, the Commission estimates
that the majority of wireless telecommunications carriers (except
satellite) are small entities that may be affected by the Commission's
proposed action. The Commission notes that the number of firms does not
necessarily track the number of licensees. The Commission estimates
that virtually all of the Fixed Microwave licensees (excluding
broadcast auxiliary licensees) would qualify as small entities under
the SBA definition.
225. Satellite Telecommunications and All Other Telecommunications.
Two economic census categories address the satellite industry. The
first category has a small business size standard of $32.5 million or
less in average annual receipts, under SBA rules. The second also has a
size standard of $32.5 million or less in annual receipts.
226. The category of Satellite Telecommunications ``comprises
establishments primarily engaged in providing telecommunications
services to other establishments in the telecommunications and
broadcasting industries by forwarding and receiving communications
signals via a system of satellites or reselling satellite
telecommunications.'' Census Bureau data for 2012 show that 333
Satellite Telecommunications firms operated for that entire year. Of
this total, 275 firms had annual receipts of under $10 million, and 58
firms had receipts of $10 million to $24,999,999. Consequently, the
Commission estimates that the majority of Satellite Telecommunications
firms are small entities that might be affected by the Commission's
action.
227. The second category, i.e., ``All Other Telecommunications,''
comprises ``establishments primarily engaged in providing specialized
telecommunications services, such as satellite tracking, communications
telemetry, and radar station operation. This industry also includes
establishments primarily engaged in providing satellite terminal
stations and associated facilities connected with one or more
terrestrial systems and capable of transmitting telecommunications to,
and receiving telecommunications from, satellite systems.
Establishments providing Internet services or voice over Internet
protocol (VoIP) services via client-supplied telecommunications
connections are also included in this industry.'' For this category,
Census Bureau data for 2012 show that there were a total of 1442 firms
that operated for the entire year. Of this total, 1400 firms had annual
receipts of under $25 million, and 42 firms had annual receipts of $25
million to $49, 999,999. Consequently, the Commission estimates that
the majority of All Other Telecommunications firms are small entities
that might be affected by the Commission's action.
228. Radio and Television Broadcasting and Wireless Communications
Equipment

[[Page 79928]]

Manufacturing. The proposed rules relating to part 15 operation pertain
to manufacturers of unlicensed communications devices. The Census
Bureau defines this category as follows: ``This industry comprises
establishments primarily engaged in manufacturing radio and television
broadcast and wireless communications equipment. Examples of products
made by these establishments are: Transmitting and receiving antennas,
cable television equipment, GPS equipment, pagers, cellular phones,
mobile communications equipment, and radio and television studio and
broadcasting equipment.'' The SBA has developed a small business size
standard for firms in this category, which is: All such firms having
750 or fewer employees. According to Census Bureau data for 2007, there
were a total of 939 establishments in this category that operated for
part or all of the entire year. Of this total, 784 had less than 500
employees and 155 had more than 100 employees. Thus, under this size
standard, the majority of firms can be considered small.
5. Description of Projected Reporting, Recordkeeping, and Other
Compliance Requirements
229. The projected reporting, recordkeeping, and other compliance
requirements proposed in the Report and Order will apply to all
entities in the same manner. The revisions the Commission adopts should
benefit small entities by giving them more information, more
flexibility, and more options for gaining access to wireless spectrum.
230. Any applicants for Upper Microwave Flexible Use Service
licenses will be required to file license applications using the
Commission's automated Universal Licensing System (ULS). ULS is an
online electronic filing system that also serves as a powerful
information tool, one that enables potential licensees to research
applications, licenses, and antenna structures. It also keeps the
public informed with weekly public notices, FCC rulemakings, processing
utilities, and a telecommunications glossary. Upper Microwave Flexible
Use Service applicants that must submit long-form license applications
must do so through ULS using Form 601, FCC Ownership Disclosure
Information for the Wireless Telecommunications Services using FCC Form
602, and other appropriate forms.
231. Licensees in the Upper Microwave Flexible Use Service will be
subject to performance requirements based on a series of metrics,
tailored to each type of service a licensee may offer. Accordingly,
mobile services will be required to provide service to 40 percent of
the population of their license area by the end of their initial
license terms. Geographic area licensees providing Fixed Service in the
28 GHz, 37 GHz and 39 GHz will be required to construct and operate at
least 15 links per million persons in the population. Satellite
operators will be able to meet their build-out requirement by deploying
an operational earth station in the license area that provides service.
Licensees deploying a mix of such services will be able to choose which
performance metric--or combination thereof--they desire to meet.
Performance will be assessed on a license area basis, regardless of
license area size. For the 28 GHz band, licenses will terminate
automatically if a licensee fails to meet the applicable performance
requirements. For geographic area licenses in the 37 and 39 GHz bands,
licensees will have the option of partitioning their licenses on a
county basis to come into compliance with the relevant performance
metric. Licensees will be required to provide information to the
Commission on the facilities they have constructed, the nature of the
service they are providing, and the extent to which they are providing
coverage in their license area, to both facilitate sharing with other
authorized services and to enable accurate assessment of their
performance. Incumbent licensees will be granted time to transition to
these new performance requirements. FSS operators will have to
coordinate their operations with any existing mmW licensees to ensure
non-interference between the services.
232. New licensees will also be required, within three years after
receiving their licenses but no later than six months prior to
deployment, to file with the Commission a security statement signed by
a senior licensee executive with personal knowledge of the licensee's
security plans and practice, which must include, at a minimum, the
following elements: (1) A high-level, general description of the
licensee's security approach designed to safeguard the planned
network's confidentiality, integrity, and availability with respect to
communications from: A device to the licensee's network; one element of
the licensee's network to another element on the licensee's network;
the licensee's network to another network; and device to device (with
respect to telephone voice and messaging services); (2) a high-level,
general description of the licensee's approach to assessing and
mitigating cyber risk induced by the presence of multiple participants
in the band. This should include the high level approach taken toward
ensuring consumer network confidentiality, integrity, and availability
security principles, which are to be protected in each of the following
use cases: Communications between a wireless device and the licensee's
network; communications within and between each licensee's network;
communications between mobile devices that are under end-to-end control
of the licensee; and communications between mobile devices that are not
under the end-to-end control of the licensee; (3) a high-level
description of relevant cybersecurity standards and practices to be
employed, whether industry-recognized or related to some other
identifiable approach; (4) a description of the extent to which the
licensee participates with standards bodies or industry-led
organizations pursuing the development or maintenance of emerging
security standards and/or best practices; (5) the high-level
identification of any other approaches to security, unique to the
services and devices the licensee intends to offer and deploy; and (6)
plans to incorporate relevant outputs from Information Sharing and
Analysis Organizations (ISAOs) as elements of the licensee's security
architecture. Plans should include comment on machine-to-machine threat
information sharing.
233. All of the filing, recordkeeping and reporting requirements
associated with the demands described above, including professional,
accounting, engineering or survey services used in meeting these
requirements will be the same for large and small businesses that
intend to utilize these new UMFUS licenses, but as described below,
several steps have been taken that will alleviate burdens on small
businesses in particular.
6. Steps Taken To Minimize Significant Economic Impact on Small
Entities, and Significant Alternatives Considered
234. The RFA requires an agency to describe any significant
alternative that it has considered in reaching its approach, which may
include the following four alternatives (among others): (1) The
establishment of differing compliance or reporting requirements or
timetables that take into account the resources available to small
entities; (2) the clarification, consolidation, or simplification of
compliance or reporting requirements under the rule for small entities;
(3) the

[[Page 79929]]

use of performance, rather than design, standards; and (4) an exemption
from coverage of the rule, or any part thereof, for small entities.
235. As noted above, the various construction and performance
requirements and their associated showings will be the same for large
and small businesses that license the Upper Microwave Flexible Use
Service bands. To the extent the same cost of complying with these
burdens is relatively greater for smaller businesses than for large
ones, these costs are necessary to effectuate the purpose of the
Communications Act, namely to further the efficient use of spectrum and
to prevent spectrum warehousing. Likewise compliance with the
Commission's service and technical rules and coordination requirements
are necessary for the furtherance of the Commission's goals of
protecting the public while also providing interference free services.
Large and small businesses must therefore comply with these rules and
requirements, but the Commission has taken steps to alleviate the
burden on small businesses that seek to comply with these requirements,
as discussed below.
236. The Report and Order provides that in the 28 GHz, 37 GHz and
39 GHz bands, mmW licensees will have the flexibility to provide any
fixed or mobile service that is consistent with their spectrum
allocation. This breaks with the recent past in which licensees were
limited to only single use licenses in these bands, and such new
flexibility benefits small businesses by giving them more avenues for
gaining access to valuable wireless spectrum. In addition, licensees
will be able to make a showing based on a combination of fixed and
mobile service, simplifying this process for all licensees including
small businesses. The Commission has also extended the existing renewal
deadlines for incumbent licensees in the 28 and 39 GHz bands, giving
these licensees, including small businesses in these bands, additional
time until 2024 to meet the performance requirements pertaining to
their current licenses.
237. Furthermore, the license areas chosen in the Report and Order
should provide spectrum access opportunities for smaller carriers by
giving them access to less densely populated areas that match their
footprints. For example, the Report and Order transitions the 28 GHz
band from being licensed on the BTA basis to a much smaller license
area--counties. Similarly, the Commission transitions the 39 GHz band
from being licensed via Economic Areas (``EAs'') to the smaller Partial
Economic Areas (``PEAs''). The Commission also uses PEAs for the 37 GHz
band, which will be newly licensed. The Commission abandons its
proposed ``hybrid licensing scheme'' in the 37 GHz band and has instead
opted to use geographic area licensing with PEAs in the upper 37.6-38.6
GHz portion with county-based licensing in the lower band (37.0-37.6
GHz). Finally, the Commission has created an unlicensed space in the
64-71 GHz band. However, the Report and Order also permits partitioning
and disaggregation by licensees in the mmW bands. While PEAs and
counties are small enough to provide spectrum access opportunities for
smaller carriers and PEAs could even be further disaggregated, these
units of area also nest within and may be aggregated to form larger
license areas. Therefore, the benefits and burdens resulting from
assigning spectrum in PEA and county license areas are equivalent for
small and large businesses. The 400 MHz shared space the Commission has
created in the lower 37 GHz band (37.0-37.6 GHz) should also provide
ease-of-entry and plenty of space for opportunistic and innovative uses
that could be developed by small businesses. These rules should enable
providers, or any entities large or small providing service in the mmW
bands, to more easily adjust their spectrum holdings and build their
networks pursuant to individual business plans. The Commission believes
this should result in small businesses having an easier time acquiring
or accessing spectrum.
238. Licensees may also adjust their geographic coverage through
auction in those areas where the Commission is permitting geographic
area auctions or through the secondary markets. The Report and Order
concludes it will auction licenses in the mmW bands in conformity with
the general competitive bidding rules set forth in part 1, subpart Q,
of the Commission's rules, and substantially consistent with the
competitive bidding procedures that have been employed in previous
auctions. The procedures the Commission has adopted contain provisions
to assist small entities in competitive bidding. The Commission will
employ the part 1 rules governing competitive bidding design,
designated entity preferences, unjust enrichment, application and
payment procedures, reporting requirements, and the prohibition on
certain communications between auction applicants. Furthermore,
qualifying ``small businesses''--those with gross revenues for the
preceding three years not exceeding $55 million--will be provided with
a bidding credit of 15 percent, and ``very small businesses''--those
with average annual gross revenues for the preceding three years not
exceeding $20 million--with a bidding credit of 25 percent. Providing
small businesses and very small businesses with bidding credits will
provide an economic benefit to small entities by making it easier for
small entities to acquire spectrum or access to spectrum in these
bands.
239. Furthermore, the Report and Order provides for licensing of
this spectrum under market-oriented rules. This includes applying the
Commission's secondary market policies and rules to all transactions
involving the use of mmW bands, which will provide greater
predictability and regulatory parity with bands licensed for mobile
broadband service. These rules should make it easier for mmW providers
to enter secondary market arrangements involving use of their spectrum.
The secondary market rules apply equally to all entities, whether small
or large. As a result, the Commission believes that this will provide
an economic benefit to small entities by making it easier for entities,
whether large or small, to enter into secondary market arrangements for
mmW spectrum.
240. The Report and Order also adopts an operability requirement
such that any device designed to operate within the 37 GHz and 39 GHz
bands (37-40 GHz) must be capable of operating on all frequencies
within those bands. This operability requirement will ensure that
devices developed for the geographic area licensed portion of the band
will also operate in the innovation shared space, making it easier for
smaller businesses with fewer resources to find equipment that can
operate across multiple bands. The technical rules in the Report and
Order will also allow licensees of the mmW spectrum to operate while
protecting licensees in nearby spectrum from harmful interference, some
of whom may be small entities.
241. Finally, the proposals to facilitate satellite service in the
28 GHz and 37.5-40 GHz bands should also assist small satellite
businesses.
7. Federal Rules That May Duplicate, Overlap, or Conflict With the
Proposed Rules
242. None.

Sec. 30.101 Initial authorizations.

Except with respect to in the 37-37.6 GHz band, an applicant must
file a single application for an initial authorization for all markets
won and frequency blocks desired. Initial authorizations shall be
granted in accordance with Sec. 30.4. Applications for individual
sites are not required and will not be accepted, except where required
for environmental assessments, in accordance with Sec. Sec. 1.1301
through 1.1319 of this chapter.


Sec. 30.102 Transition of existing local multipoint distribution
service and 39 GHz licenses.

Local Multipoint Distribution Service licenses in the 27.5--28.35
GHz band issued on a Basic Trading Area basis shall be disaggregated
into county-based licenses and 39 GHz licenses issued on an Economic
Area basis shall be disaggregated into Partial Economic Area-based
licenses on December 14, 2016. For each county in the Basic Trading
Area or Partial Economic Area in the Economic Area which is part of the
original license, the licensee shall receive a separate license. If
there is a co-channel Rectangular Service Area licensee within the
service area of a 39 GHz Economic Area licensee, the disaggregated
license shall not authorize operation with the service area of the
Rectangular Service Area license.


Sec. 30.103 License term.

Initial authorizations will have a term not to exceed ten years
from the date of initial issuance or renewal.


Sec. 30.104 Construction requirements.

(a) Upper Microwave Flexible Use Service licensees must make a
buildout showing as part of their renewal applications. Licensees
relying on mobile or point-to-multipoint service must show that they
are providing reliable signal coverage and service to at least 40
percent of the population within the service area of the licensee, and
that they are using facilities to provide service in that area either
to customers or for internal use. Licensees relying on point-to-point
service must demonstrate that they have four links operating and
providing service, either to customers or for internal use, if the
population within the license area is equal to or less than 268,000. If
the population within the license area is greater than 268,000, a
licensee relying on point-to-point service must demonstrate it has at
least one link in operation and is providing service for each 67,000
population within the license area.
(b) Showings that rely on a combination of multiple types of
service will be evaluated on a case-by-case basis.
(c) If a licensee in this service is also a Fixed-Satellite Service
licensee and uses the spectrum covered under its UMFUS license in
connection with a satellite earth station, it can demonstrate
compliance with the requirements of this section by demonstrating that
the earth station in question is in service, operational, and using the
spectrum associated with the license. This provision can only be used
to demonstrate compliance for the county in which the earth station is
located.
(d) Failure to meet this requirement will result in automatic
cancellation of the license. In bands licensed on a Partial Economic
Area basis, licensees will have the option of partitioning a license on
a county basis in order to reduce the population within the license
area to a level where the licensee's buildout would meet one of the
applicable performance metrics.
(e) Existing 28 GHz and 39 GHz licensees shall be required to make
a showing pursuant to this rule by June 1, 2024.


Sec. 30.105 Geographic partitioning and spectrum disaggregation.

(a) Parties seeking approval for partitioning and disaggregation
shall request from the Commission an authorization for partial
assignment of a license pursuant to Sec. 1.948 of this chapter. Upper
Microwave Flexible Use Service licensees may apply to partition their
licensed geographic service area or disaggregate their licensed
spectrum at any time following the grant of their licenses.
(b) Technical standards--(1) Partitioning. In the case of
partitioning, applicants and licensees must file FCC Form 603 pursuant
to Sec. 1.948 of this chapter and list the partitioned service area on
a schedule to the application. The geographic coordinates must be
specified in degrees, minutes, and seconds to the nearest second of
latitude and longitude and must be based upon the 1983 North American
Datum (NAD83).
(2) Spectrum may be disaggregated in any amount.
(3) The Commission will consider requests for partial assignment of
licenses that propose combinations of partitioning and disaggregation.
(4) For purposes of partitioning and disaggregation, part 30
systems must be designed so as not to exceed the signal level specified
for the particular spectrum block in Sec. 30.204 at the licensee's
service area boundary, unless the affected adjacent service area
licensees have agreed to a different signal level.
(c) License term. The license term for a partitioned license area
and for disaggregated spectrum shall be the remainder of the original
licensee's license term as provided for in Sec. 30.103.
(d)(1) Parties to partitioning agreements must satisfy the
construction requirements set forth in Sec. 30.104 by the partitioner
and partitionee each certifying that it will independently meet the
construction requirement for its respective partitioned license area.
If the partitioner or partitionee fails to meet the construction
requirement for its respective partitioned license area, then the
relevant partitioned license will automatically cancel.
(2) Parties to disaggregation agreements must satisfy the
construction requirements set forth in Sec. 30.104 by the
disaggregator and disaggregatee each certifying that it will
independently meet the construction requirement for its respective
disaggregated license area. If the disaggregator or disaggregatee fails
to meet the construction requirement for its respective disaggregated
license area, then the relevant disaggregated license will
automatically cancel.


Sec. 30.106 Discontinuance of service.

(a) An Upper Microwave Flexible Use License authorization will
automatically terminate, without specific Commission action, if the
licensee permanently discontinues service after the initial license
term.
(b) For licensees with common carrier regulatory status, permanent
discontinuance of service is defined as 180 consecutive days during
which a licensee does not provide service to at least one subscriber
that is not affiliated with, controlled by, or related to the licensee
in the individual license area. For licensees with non-common carrier
status, permanent discontinuance of service is defined as 180
consecutive days during which a licensee does not operate.
(c) A licensee that permanently discontinues service as defined in
this section must notify the Commission of the discontinuance within 10
days by filing FCC Form 601 or 605 requesting license cancellation. An
authorization will automatically terminate, without specific Commission
action, if service is permanently discontinued as defined in this
section, even if a licensee fails to

[[Page 79941]]

file the required form requesting license cancellation.

Subpart C--Technical Standards


Sec. 30.201 Equipment authorization.

(a) Except as provided under paragraph (c) of this section, each
transmitter utilized for operation under this part must be of a type
that has been authorized by the Commission under its certification
procedure.
(b) Any manufacturer of radio transmitting equipment to be used in
these services may request equipment authorization following the
procedures set forth in subpart J of part 2 of this chapter. Equipment
authorization for an individual transmitter may be requested by an
applicant for a station authorization by following the procedures set
forth in part 2 of this chapter.
(c) Unless specified otherwise, transmitters for use under the
provisions of subpart E of this part for fixed point-to-point microwave
and point-to-multipoint services must be a type that has been verified
for compliance.


Sec. 30.202 Power limits.

(a) For fixed and base stations operating in connection with mobile
systems, the average power of the sum of all antenna elements is
limited to an equivalent isotopically radiated power (EIRP) density of
+75dBm/100 MHz. For channel bandwidths less than 100 megahertz the EIRP
must be reduced proportionally and linearly based on the bandwidth
relative to 100 megahertz.
(b) For mobile stations, the average power of the sum of all
antenna elements is limited to a maximum EIRP of +43 dBm.
(c) For transportable stations, as defined in Sec. 30.2, the
average power of the sum of all antenna elements is limited to a
maximum EIRP of +55 dBm.
(d) For fixed point-to-point and point-to-multipoint limits see
Sec. 30.405.


Sec. 30.203 Emission limits.

(a) The conductive power or the total radiated power of any
emission outside a licensee's frequency block shall be -13 dBm/MHz or
lower. However, in the bands immediately outside and adjacent to the
licensee's frequency block, having a bandwidth equal to 10 percent of
the channel bandwidth, the conductive power or the total radiated power
of any emission shall be -5 dBm/MHz or lower.
(b)(1) Compliance with this provision is based on the use of
measurement instrumentation employing a resolution bandwidth of 1
megahertz or greater.
(2) When measuring the emission limits, the nominal carrier
frequency shall be adjusted as close to the licensee's frequency block
edges as the design permits.
(3) The measurements of emission power can be expressed in peak or
average values.
(c) For fixed point-to-point and point-to-multipoint limits see
Sec. 30.404.


Sec. 30.204 Field strength limits.

(a) Base/mobile operations: The predicted or measured Power Flux
Density (PFD) from any Base Station operating in the 27.5-28.35 GHz
band, 37-38.6 GHz band, and 38.6-40 GHz bands at any location on the
geographical border of a licensee's service area shall not exceed -
76dBm/m\2\/MHz (measured at 1.5 meters above ground) unless the
adjacent affected service area licensee(s) agree(s) to a different PFD.
(b) Fixed point-to-point operations. (1) Prior to operating a fixed
point-to-point transmitting facility in the 27,500-28,350 MHz band
where the facilities are located within 20 kilometers of the boundary
of the licensees authorized market area, the licensee must complete
frequency coordination in accordance with the procedures specified in
Sec. 101.103(d)(2) of this chapter with respect to neighboring
licensees that may be affected by its operations.
(2) Prior to operating a fixed point-to-point transmitting facility
in the 37,000-40,000 MHz band where the facilities are located within
16 kilometers of the boundary of the licensees authorized market area,
the licensee must complete frequency coordination in accordance with
the procedures specified in Sec. 101.103(d)(2) of this chapter with
respect to neighboring licensees that may be affected by its
operations.


Sec. 30.205 Federal coordination requirements.

(a) Licensees in the 37-38 GHz band located within the zones
defined by the coordinates in the tables below must coordinate their

of the band via the National Telecommunications and Information
Administration (NTIA). All licensees operating within the zone defined
by the 60 dBm/100 MHz EIRP coordinates in the tables below must
coordinate all operations. Licensees operating within the area between
the zones defined by the 60 dBm and 75 dBm/100 MHz EIRP coordinates in
the tables below must coordinate all operations if their base station
EIRP is greater than 60 dBm/100 MHz or if their antenna height exceeds
100 meters above ground level. Licensees operating outside the zones
defined by the 75 dBm/100 MHz EIRP coordinates in the tables below are

------------------------------------------------------------------------
Maximum
Frequency band (MHz) authorized
bandwidth
------------------------------------------------------------------------
27,500 to 28,350........................................ 850 MHz.
38,600 to 40,000........................................ 200 MHz.\1\
------------------------------------------------------------------------
\1\ For channel block assignments in the 38,600-40,000 MHz bands when
adjacent channels are aggregated, equipment is permitted to operate
over the full channel block aggregation without restriction.

Sec. 30.404 Emission limits.

(a) The mean power of emissions must be attenuated below the mean
output power of the transmitter in accordance with the following
schedule:
(1) When using transmissions other than those employing digital
modulation techniques:
(i) On any frequency removed from the assigned frequency by more
than 50 percent up to and including 100 percent of the authorized
bandwidth: At least 25 decibels;
(ii) On any frequency removed from the assigned frequency by more
than 100 percent up to and including 250 percent of the authorized
bandwidth: At least 35 decibels;
(iii) On any frequency removed from the assigned frequency by more
than 250 percent of the authorized bandwidth: At least 43 + 10
Log10 (mean output power in watts) decibels, or 80 decibels,
whichever is the lesser attenuation.
(2) When using transmissions employing digital modulation
techniques in situations not covered in this section:
(i) In any 1 MHz band, the center frequency of which is removed
from the assigned frequency by more than 50 percent up to and including
250 percent of the authorized bandwidth: As specified by the following
equation but in no event less than 11 decibels:


[[Page 79944]]


A = 11 + 0.4(P-50) + 10 Log10 B. (Attenuation greater than
56 decibels or to an absolute power of less than -13 dBm/1MHz is not
required.)
(ii) In any 1 MHz band, the center frequency of which is removed
from the assigned frequency by more than 250 percent of the authorized
bandwidth: At least 43 + 10 Log10 (the mean output power in
watts) decibels, or 80 decibels, whichever is the lesser attenuation.
The authorized bandwidth includes the nominal radio frequency bandwidth
of an individual transmitter/modulator in block-assigned bands.
Equipment licensed prior to April 1, 2005 shall only be required to
meet this standard in any 4 kHz band.
(iii) The emission mask in paragraph (a)(2)(i) of this section
applies only to the band edge of each block of spectrum, but not to
subchannels established by licensees. The value of P in the equation is
the percentage removed from the carrier frequency and assumes that the
carrier frequency is the center of the actual bandwidth used. The
emission mask can be satisfied by locating a carrier of the subchannel
sufficiently far from the channel edges so that the emission levels of
the mask are satisfied. The emission mask shall use a value B
(bandwidth) of 40 MHz, for all cases even in the case where a narrower
subchannel is used (for instance the actual bandwidth is 10 MHz) and
the mean output power used in the calculation is the sum of the output
power of a fully populated channel. For block assigned channels, the
out-of-band emission limits apply only outside the assigned band of
operation and not within the band.
(b) [Reserved]


Sec. 30.405 Transmitter power limitations.

On any authorized frequency, the average power delivered to an
antenna in this service must be the minimum amount of power necessary
to carry out the communications desired. Application of this principle
includes, but is not to be limited to, requiring a licensee who
replaces one or more of its antennas with larger antennas to reduce its
antenna input power by an amount appropriate to compensate for the
increased primary lobe gain of the replacement antenna(s). In no event
shall the average equivalent isotropically radiated power (EIRP), as
referenced to an isotropic radiator, exceed the following:

Maximum Allowable EIRP
------------------------------------------------------------------------
Frequency band (MHz) Fixed (dBW)
------------------------------------------------------------------------
27,500-28,350\1\........................................ + 55
38,600-40,000........................................... + 55
------------------------------------------------------------------------
\1\ For Point-to-multipoint user stations authorized in these bands, the
EIRP shall not exceed 55 dBw or 42 dBw/MHz.

Sec. 30.406 Directional antennas.

(a) Unless otherwise authorized upon specific request by the
applicant, each station authorized under the rules of this subpart must
employ a directional antenna adjusted with the center of the major lobe
of radiation in the horizontal plane directed toward the receiving
station with which it communicates: provided, however, where a station
communicates with more than one point, a multi- or omni-directional
antenna may be authorized if necessary.
(b) Fixed stations (other than temporary fixed stations) must
employ transmitting and receiving antennas (excluding second receiving
antennas for operations such as space diversity) meeting the
appropriate performance Standard A indicated in the table to this
section, except that in areas not subject to frequency congestion,
antennas meeting performance Standard B may be used. For frequencies
with a Standard B1 and a Standard B2, in order to comply with Standard
B an antenna must fully meet either Standard B1 or Standard B2.
Licensees shall comply with the antenna standards table shown in this
paragraph in the following manner:
(1) With either the maximum beamwidth to 3 dB points requirement or
with the minimum antenna gain requirement; and
(2) With the minimum radiation suppression to angle requirement.

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Minimum radiation suppression to angle in degrees from centerline of main beam in
