Following the article R20-44-11 of the Post and electronic communication code (CPCE), ANFR is « responsible for the international coordination of the frequency at the borders »
The coordination of the terrestrial services is regulated by Agreements defined at the ITU regional level and/or at the multilateral level. These agreements describe the negotiated rights for each signatory administration as well as the rules for their modification if appropriate. More precisely the role of the ANFR could be derived in 3 main tasks.
Negotiation and update of the cross border agreements.
The Agency leads the cross border frequency negotiation mainly for :
- The television and radio (broadcasting service) in collaboration with CSA
- The public mobile networks (mobile service for 2G, 3G, 4G) in collaboration with ARCEP
- the private networks (PMR) and fixed links (microwaves) in collaboration with the affectataires
The task of frequency coordination by the mean of global agreement is mainly done for broadcasting, fixed and mobile services and can be completed by specific agreements. When these agreements exist or that general rules are enough, as in the other frequency bands, it is necessary to determine the potential impact of each new project on each sides of the border. These studies are done on a case by case basis and are necessary before each signature of a global agreement in order to preserve the interests of France in the framework of these negociations.
Harmful interference cases
The international coordination aims to avoid hamrfull interferences between the networks on each sides of the border. Nevertheless some cases may occur. Following the article 43 of the CPCE, the ANFR is responsible for collecting the complaints and manage the interferences cases.
In the situation that an agreement is in force, concertation meetings with the colleagues of the neighbouring countries are organized with the operators of each country in order to study each case with the lights of the rules of the agreements, which could lead, in some specific cases to the revision of the agreement.
In the situation that no agreement is in force, the global framework defined by the Radio Regulations (RR) apply and, in particular, the anteriority principle for the records in the MIFR (see next section). ANFR takes contact with the neighboring administrations and affected operators in order to identify the origin of the interference and to find technical solution in order to stop the interference. Depending on the origin of the interference, these discussions may lead to the definition of a cross border agreement.
Registration in the MIFR
ANFR proceeds to the notification of the french assignments that must be registred in the MIFR (Master International Frequency Register).
This reference file contains the frequency assignments and their technical characteristics as notified at the ITU. As described before if no agreement is signed, the rules of the ITU and Radio Regulations apply, thus the first registered in the file has the international recognition as define in the article 8.3 of the RR “Any frequency assignment recorded in the Master Register with a favourable finding under No. 11.31 shall have the right to international recognition. For such an assignment, this right means that other administrations shall take it into account when making their own assignments, in order to avoid harmful interference. In addition, frequency assignments in frequency bands subject to coordination or to a plan shall have a status derived from the application of the procedures relating to the coordination or associated with the plan.”
