After deliberating on 9 September 2008,
For the following reasons:
On the legal framework:
The frequency band 8 025-8 500 MHz is assigned in the National Frequency Band Distribution Table (TNRBF) to the Electronic Communications and Post Control Authority for the establishment of fixed service links with a status equal to other affectataries in the 8 025-8 400 MHz and a priority status in the 8 400-8 500 MHz subband. ARCEP is the coordinator of this band for fixed service.
The conditions for use of the frequency band 8 025-8 500 MHz were fixed by the Decision No. 97-390 of 13 November 1997 and No. 99-37 of 12 January 1999. The purpose of this decision is to amend these conditions of use in this band of frequencies for the fixed service, replacing the two above-mentioned decisions it repeals.
Pursuant to Article 3. 2 of Directive 1999 / 5 / EC, uses must meet essential requirements. For this, it is possible to refer to the EN 302 217 standard of the European Telecommunications Standards Institute (ETSI).
In accordance with Directive 1998 / 34 / The above-mentioned EC, the radio interfaces defined in this decision are notified to the European Commission.
On the evolution of the conditions of use:
The band 8 025-8 500 MHz, historically used for analog audiovisual transport and open-ended electronic communications networks, has so far been structured around four distinct frequency plans:
– bi-directional point-to-point connections to public-open electronic communications networks, operating with a channel at the pace of 7, 14, 28 or 32, 5 MHz;
– digital unidirectional point-to-point links for the transport of audiovisual programs, operating with a 28 MHz channel;
― unidirectional point-to-point links for the transport of audiovisual programs, operating with a 3, 5 MHz channel;
– analog unidirectional point-to-point connections for the transport of audiovisual programs, operating with a 32, 5 MHz channel.
This decision makes two amendments in technical terms:
– deletion of the line at 32, 5 MHz for unidirectional and bidirectional point-to-point connections not in accordance with ITU-R plan F. 386-7;
― widening to all pipelines authorized by the ITU-R plan F. 386-7 (7, 14 and 28 MHz) of possible pipelines for limited unidirectional links up to now to a 28 MHz channel.
As a result of technological developments and the digitalization of associated services, there are now no requests for analog services and it is expected that, in the medium term, existing links will be lost in accordance with theArticle 99 of the Act of 30 September 1986 modified that sets the analog television stop on 30 November 2011. However, in order to facilitate the transfer of the analog transport network to a digital transport network, the Autorité reserves the right to authorize analog links for a limited period of time. As a result, the 32, 5 MHz channel is not perpetuated for the authorization of new connections. The elimination of analog links at 32, 5 MHz will facilitate the development of digital links in accordance with the ITU-R F. 386-7 plan on pipelines at 7, 14 and 28 MHz.
In this regard, the market for radio infrastructure networks is growing steadily, given the competitiveness of these technical solutions in relation to wire and satellite technologies. This growth results in intensive use, including bands of frequencies 6 GHz and 13 GHz for point-to-point connections. Therefore, it becomes necessary to develop the use of frequencies in the band 8 025-8 500 MHz, in order to provide additional frequencies to these networks.
Thus the new conditions define the following plans:
Digital two-way point-to-point links for the benefit of open-ended electronic communications networks, operating with a 7.14 or 28 MHz channel;
Digital unidirectional point-to-point connections operating with a 7.14 or 28 MHz channelling;
Given the specificity of applications using the channel at the 3, 5 MHz step and in the absence of interaction with the ITU-R plan in force for the other pipelines, this one, a legacy of a specific French situation, is not intended to be modified in the future. The three plans dedicated to single point-to-point systems using a 3, 5 MHz channel are maintained:
―f0 = central frequency: 8,026, 25 MHz;
fn = central frequency of a channel in MHz;
fn (MHz) = f0 + 3, 5 n;
- n = 1 to 10, 64 to 66 and 125 to 134.
In addition, in order to develop the use of this band while seeking to optimize its use, the terms and conditions of use set out in this decision maintain the pipeline at a 3, 5 MHz step for unidirectional bonds consistent with ITU-R recommendation F. 386-7 and primarily its annex 5.
Recommendations for use:
In order to ensure a balance between the use of fixed service and other services in this band, overall coherence with all the frequencies of the fixed service and, optimizing the coordination of bonds guaranteeing the absence of interference, the following conditions of use, defined at the national level, are recommended:
Pursuant to the Decree of 24 October 2007 on the application of Decree No. 2007-1532 on the royalties of use of radio frequencies:
The minimum length of the connections is:
13 km for a flow of less than or equal to 51 Mbit / s;
10 km for flow greater than 51 Mbit / s,
and by exception, 4 km for unidirectional point-to-point connections using a 3, 5 MHz nozzle.
The minimum modulation type is:
4 states for pipelines at 3, 5 MHz;
16 states for pipes greater than or equal to 7 MHz.
Management principles:
The maximum equivalent radiated isotropic power (PIRE) is limited in order to optimize the reuse of the spectrum while not obtaining the standard performance of the connections. The PIRE will be specified by the Authority for the regulation of electronic communications and posts based on polarization, the objective of availability of the geographic location area, weakening due to precipitation, fainting due to the spread by multiple routes and the length of the link.
The Authority will focus on respect for the parity of the sites, i.e., in a band considered, the frequency of emission of all radio stations of the same site must be in the same sub-band (bass or high). In fact, a bidirectional link uses a couple of frequencies positioned for each of them in a subband of so-called low or high frequencies. These are separated by a so-called duplex deviation. Parity means the frequency subband used absolutely on a given site. This parity system allows the optimal use of all available frequencies for one of the two subbands. The parity of a site is determined by the first radio station declared,
Decides:
The radio interface specification described in the appendix to this decision defines the conditions for use of the frequency band 8 025-8 500 MHz for fixed service applications.
This decision applies to all new frequency usage authorizations for fixed service applications in the band, as well as renewals.
The decisions of the Authority No. 97-390 dated 13 November 1997 setting out the general operating and technical conditions of the frequency band 8-8,5 GHz for the transmission links of sound broadcasting programs, and No. 99-37 dated 12 January 1999 setting the channel to be used by the digital transmission modulation devices point-to-point of the fixed service in the band 8 025-8 500 MHz are repealed at the time of the decision
The Director General of the Authority is responsible for the execution of this decision, which will be, after approval by order of the Minister for Electronic Communications, published in the Official Journal of the French Republic.
