Summary of the Report and Order
1. On May 13, 2004, the Commission adopted a Notice of Proposed Rule Making (NPRM), 69 FR 34103, June 18, 2004, in this proceeding in which it proposed to allow unlicensed operation in the TV bands at locations where frequencies are not in use by licensed services. To ensure that no harmful interference to TV stations and other authorized users of the spectrum will occur, the Commission proposed to define when a TV channel is unused and to require unlicensed devices to incorporate “smart radio” features to identify the unused TV channels in the area where they are located. For the purpose of establishing a plan for minimizing interference, the Commission proposed to classify unlicensed broadband devices to be used in the TV bands into two general functional categories. The first category would consist of lower power “personal/portable” unlicensed devices, such as Wi-Fi like cards in laptop computers or wireless in-home local area networks (LANs). The second category would consist of higher power “fixed/access” unlicensed devices that are generally operated from a fixed location and may be used to provide a commercial service such as wireless broadband Internet access. The Commission proposed that fixed/access devices incorporate a geo-location method such as a Global Positioning System (GPS) receiver or be professionally installed, and that they must access a database to identify vacant channels at their location. It proposed to require that personal/portable devices operate only when they receive a control signal from a source such as an FM or TV station that identifies the vacant TV channels in that particular area. The Commission also sought comment on the use of spectrum sensing to identify vacant TV channels, but did not propose any specific technical criteria for spectrum sensing.
2. In the First Report and Order , the Commission takes a number of important first steps towards allowing the introduction of new low power devices in the broadcast television spectrum (TV bands) on channels/frequencies that are not being used for authorized services (hereinafter referred to as “TV band devices”). The goal in this proceeding is to allow such devices to operate on unused television channels in locations where such operations will not result in harmful interference to TV and other authorized services. The Commission believes that this plan will provide for more efficient and effective use of the TV spectrum and will significantly benefit the public by allowing the development of new and innovative types of devices and services for businesses and consumers, without disrupting television and other authorized services using the TV bands. Because transmissions in the TV band are subject to less propagation attenuation than transmissions in other bands where lower power operations are permitted (such as unlicensed operations in the 2.4 GHz band), operations in the TV bands can benefit a wide range of service providers and consumers by improving the service range of wireless operations, thereby allowing operators to reach new customers. While there will be significant benefits to the public from its actions, the Commission recognizes that it must balance these benefits with the need to protect authorized services in the TV bands from harmful interference.
3. The Commission also recognizes the importance of conducting tests to ensure that whatever standards are ultimately adopted for TV band devices will protect incumbent radio services from harmful interference. Given the complex and novel sharing issues presented here, it intends to conduct several types of testing, and also encourages interested parties to conduct tests and submit their results into the record of this proceeding. Interested parties that conduct their own tests for the record should provide a test plan that explains in detail the assumptions used and the reasons supporting them.
4. In order to provide sufficient time for the Commission and industry to develop appropriate technical standards for TV band products as well as lead time for industry to design and produce new products, it intends to adopt a Second Report and Order specifying final requirements for devices in the TV bands in the fall of 2007. This will allow the Commission's Laboratory to begin accepting applications for certification of these devices in the TV bands by late 2007. Certification will be granted if the application, upon review, is found to comply with the new technical rules and will allow the manufacture and shipment of products to distribution points. These devices will not be available for sale at retail until after the DTV transition ends on February 17, 2009.
5. The Commission is convinced based on the record in this proceeding that it can adopt rules to allow fixed low power operation on unused spectrum in the TV bands without causing harmful interference to authorized services. There are several factors supporting this conclusion. First, upon completion of the DTV transition, there will be significant unused TV spectrum available in many areas in the country, either because of the separations required between authorized stations to avoid interference or because available TV channels have not been assigned and other services are not using vacant channels. Also, based on the Commission's experience in developing rules for U-NII devices, it believes that it is reasonable to expect that existing technology, such as that used for spectrum sensing, can be adapted to allow devices to identify unused spectrum in a given geographic area and thus allow sharing of the TV bands. Further, the Commission notes that the IEEE 802.22 working group with broad based support is in the process of developing a standard to enable fixed devices to successfully share spectrum with authorized services in the TV bands. Finally, these devices will operate at relatively low power levels and, it is easier to protect incumbent operations in the TV bands, including wireless microphones, when devices are limited to fixed operation.
6. The Commission will exclude low power devices from operating on TV channels 37 and 52-69 to prevent interference to radio astronomy operations and the WMTS on channel 37. Also, channels 52-69 have been reallocated for services other than broadcast television and will no longer be part of the TV bands after the transition. The Commission will also exclude personal/portable TV band devices from operating on channels 14-20 in all areas of the country to prevent possible interference to public safety and other operations in the PLMRS/CMRS. Because personal/portable devices are easily transported and used anywhere, the Commission believes that the most prudent approach to protecting public safety and other PLMRS/CMRS operations on channels 14-20 is to prohibit personal/portable low power TV band devices from operating on those channels in all areas of the country.
7. Implementation Date. The Commission will allow low power TV band devices to be marketed immediately after the end of the DTV transition on February 17, 2009, but not before. The Commission believes that this schedule is appropriate for several reasons. First, there are fewer vacant channels available during the DTV transition because most TV stations are currently broadcasting both an analog and a digital signal. There are thus about twice as many TV channels in use now as there will be after the end of the transition when full service analog broadcasting ceases. Also, the TV band is in a state of flux as the Commission develops the final DTV table of allotments and some TV stations still must change channels. In this regard, there will be adjustments in DTV channels that affect the availability of channels in individual markets throughout the remainder of the transition. The Commission also notes the concerns of a number of parties about possible disruption to the DTV transition if unlicensed devices are permitted to operate in the TV bands prior to the end of the DTV transition. The Commission believes that the risk of creating uncertainty that would impede the DTV transition outweighs the benefit of allowing operation of low power devices at a slightly earlier date, especially given that some proponents of low power devices have indicated they would need up to 21 months after the adoption of final technical rules to bring such devices to market. For these reasons, the Commission will allow TV band devices on the market only after the end of DTV transition.
Final Regulatory Flexibility Certification
8. The Regulatory Flexibility Act of 1980, as amended (RFA) 1
requires that a regulatory flexibility analysis be prepared for rulemaking proceedings, unless the agency certifies that “the rule will not have a significant economic impact on a substantial number of small entities.” 2
The RFA generally defines “small entity” as having the same meaning as the terms “small business,” “small organization,” and “small governmental jurisdiction.” 3
In addition, the term “small business” has the same meaning as the term “small business concern” under the Small Business Act. 4
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 Small Business Administration (SBA). 5
9. In the First Report and Order , the Commission decides to allow low power fixed devices to operate on unused spectrum on TV channels 5-13, and 21-51, excluding channel 37. Operation will not be permitted prior to further action by the Commission to develop technical rules that allow devices to operate on those channels without causing interference. Because the Report and Order does not adopt any rules or other compliance requirements, the Commission certifies that the actions in the First Report and Order will not have a significant economic impact on a substantial number of small entities. The Commission will send a copy of the First Report and Order including a copy of this final certification, in a report to Congress pursuant to the Small Business Regulatory Enforcement Fairness Act of 1996, see 5 U.S.C. 801(a)(1)(A). In addition, the First Report and Order and this certification will be sent to the Chief Counsel for Advocacy of the Small Business Administration, and will be published in the Federal Register . See 5 U.S.C. 605(b).
