N001 Why should the frequency assignments be notified to the ITU?
The frequency assignments that may have international implications, as well as those for which the administration wishes to obtain international recognition, have to be notified to the ITU with a view to their recording in the Master International Frequency Register (MIFR). Once recorded in the MIFR, the concerned frequency assignments get an appropriate status that determines their relationship in respect to frequency assignments of other administrations. Consequently, some of the international rights can be claimed only in respect to those frequency assignments that are recorded in the MIFR, provided that the concerned frequency assignments got the appropriate status.
N002 What is the Master International Frequency Register (MIFR)?
The Master International Frequency Register (MIFR) is the ITU database in which all frequency assignments are registered.
N003 When is there no need to notify?
The following frequency assignments do not need to be notified:
  • Frequency assignments involving specific frequencies which are prescribed for common use, as specified in RR No. 11.13;
  • Frequency assignments to ship stations and to mobile stations of other services, as specified in RR No. 11.14;
  • Frequency assignments to stations in the amateur service, as specified in RR No. 11.14;
  • Frequency assignments to receiving aeronautical stations in the bands governed by Appendices 26 and 27, as all communications in these bands are made in simplex mode of operation, as specified in the Rule of Procedure related to RR 11.14.
N004 Which assignments are to be notified?
Any frequency assignment has to be notified to BR if:
  • its use is likely to cause harmful interference;
  • it will be used for international communications;
  • its use is governed by a plan;
  • its use is subject to a coordination procedure (Article 9);
  • there is a desire to secure international recognition of its use.
If an assignment is not consistent with the Table of Frequency Allocations or other provisions of the Regulations, an administration may also request that it should be included in the Master Register solely for information purposes. When an administration considers that the above conditions are met, it submits appropriate notice forms indicating the relevant characteristics of the frequency assignment, as specified in Appendix 4 of the Radio Regulations. When an assignment is no longer used, its cancellation is also to be notified.
N005 In what units are frequencies to be notified?
  • kHz for frequencies up to 28 000 kHz inclusive;
  • MHz for frequencies from 28 000 kHz to 10 500 MHz inclusive;
  • GHz for frequencies above 10 500 MHz.
N006 Which frequency assignments have to be notified individually?
Individual notices are required for the following cases:
  • Assignments to stations governed by Allotment Plans of Appendices 25, 26 and 27 and by any frequency assignment plan;
  • Assignments to stations of the broadcasting service in any band;
  • Assignments to stations of all terrestrial services which are within the coordination area of an earth station;
  • Assignments to any stations in the bands shared with space services with equal rights if they exceed the limits specified in the appropriate Tables of Appendix 7 and in RR No. 21.3;
  • Assignments to terrestrial stations in the bands shared with space services and listed in Table 21.2.
In all other cases administrations may opt for notification of typical stations, i.e., to supply only the basic characteristics of a typical station, which represents the frequency use of a large number of stations within a given geographical area of operation.
N007 When should notification of frequency assignments be submitted to the Bureau?
The following deadlines are applicable to notices in terrestrial services:
  • Five years before the assignment is brought into use, for assignments to high altitude platform stations in the fixed service in the bands 47.2- 47.5 GHz and 47.9 - 48.2 GHz (see RR No. 11.26);
  • Three years before the assignment is brought into use, for terrestrial stations involved in coordination with a satellite network (i.e., if the terrestrial station is operating in band shared with a space service and located within the coordination area of receiving earth station) - see RR No. 11.25;
  • Three months before the assignment is brought into use, for all other terrestrial stations (see RR No. 11.24).
N008 Is the recording in the Master Register a straightforward action?
The recording of a frequency assignment in the Master Register is preceded by various examinations so as to determine the conformity of the concerned frequency assignment with those conditions that could determine its status. Each notice is examined with respect to:
  • the conformity with the Table of Frequency Allocations and the other provisions of the Radio Regulations (regulatory examination); this examination consists in checking that the assignment (frequency, class of station, notified bandwidth) does indeed correspond to an allocation in the Table of Frequency Allocations in Article 5 or the footnotes thereto and, where appropriate, that it complies with other technical or operating conditions laid down in other Articles or Appendices of the Radio Regulations (power limits, authorized classes of emission, minimum elevation angle);
  • the conformity with the procedures relating to coordination with other administrations applicable to the radiocommunication service and the frequency band concerned;
  • the conformity with a world or regional allotment or assignment plan and the associated provisions (if the frequency assignment is related to a radiocommunication service which is subject to a plan in the frequency band concerned).
If all the results of these examinations, as applicable, are favourable, the assignment is recorded in the MIFR. Otherwise, the notice is returned to the notifying administration after publication of the finding in BR IFIC.
N009 What else should the Administration do once the frequency is recorded?
The recording in the Master Register does not mean an end of activities of the notifying administration in respect to the concerned frequency assignment. The notifying administration should remain in close cooperation with the licensing authority and any change in the characteristics of the concerned assignment has to be notified to the BR, so as to reflect them in the Master Register, if necessary after additional coordination with the administrations of countries concerned. Furthermore, notifying administrations should remain in close contact with the monitoring authority so as to check whether the concerned frequency assignment is operated in compliance with the notified characteristics and whether other elements (e.g., frequency tolerance) are kept within the limits prescribed by the Radio Regulations. Notifying administrations should also initiate appropriate monitoring programs with a view to detecting any operational or technical irregularities in the operation of frequency assignments from other administrations, and to initiate appropriate actions in this regard, so as to ensure interference-free operation for stations under its jurisdiction.
N010 I want to notify an assignment to a VHF FM sound broadcasting station. Which notice should I use?
Notice T01 is used to notify assignments to VHF FM sound broadcasting station.
N011 I want to notify an assignment to a television station. Which notice should I use?
Notice T02/G02 is used to notify assignments to television broadcasting stations.
N012 When should notice TB1 be used?
Notice TB1 is used to modify the unique identification code given by the administration to the assignment or allotment.
N013 When should notice TB2 be used?
Notice TB2 is used to notify, under Article 11, an assignment with all technical characteristics as in the plan.
N014 When should notice TB3 be used?
Notice TB3 is used to request publication of a modification in part B of the corresponding special section.
N015 When should notice TB4 be used?
Notice TB4 is used to update the coordination information of a notice under treatment.
N016 When should notice TB5 be used?
Notice TB5 is used to suppress an assignment or withdraw a notice under treatment. Do not enter the BR identification number formerly used by the Bureau to identify an assignment under "Administration unique identifier of the target". If the administration unique identifier has not been registered earlier, just give the frequency and coordinates of the assignment to be suppressed (if the assignment has already been registered) or withdrawn (if the assignment is under treatment).
N017 I have to authorize the installation of a new FM sound broadcasting or television station in an unplanned band. What should I do?
In this case it is necessary to apply either the procedure in Article 11 of the Radio Regulations, or the procedure in RR 9.21 followed by the Article 11 procedure if the band is subject to a coordination procedure.
N018 I want to notify an assignment to a fixed station. Which notice form should I use?
The one to use in this case is notice form T11 for the notification of assignments to terrestrial transmitting stations in the fixed service.
N019 I want to notify an assignment to a base station. Which notice form should I use?
The one to use in this case is notice form T12 for the notification of assignments to terrestrial transmitting stations (except stations in the fixed or LF/MF/VHF/UHF broadcasting services, or typical stations).
N020 I want to notify an assignment to a mobile station. Which notice form should I use?
The one to use in this case is notice form T13 for the notification of assignments to terrestrial receiving land stations.
N021 I want to notify an assignment to a typical station. Which notice form should I use?
The one to use in this case is notice form T14 for the notification of assignments to terrestrial typical transmitting stations.
N022 When should a station be notified as a typical station?
Very often the same frequency is reused repeatedly in one and the same country, e.g. in the case of mobile networks. To avoid having to notify each frequency assignment by station separately, it has been arranged that only one notice should be sent, giving the standard characteristics of the network station for each of the frequencies used.
N023 I have to authorize the installation of a new FM sound broadcasting or television station in a planned band. What should I do?
There are two possibilities: There is still an assignment free in the Plan in question, and the license can be issued to the operator immediately if the characteristics entered in the Plan will enable the applicantīs needs to be met. If so, the assignment is notified under Article 11 of the Radio Regulations for entry in the Master Register. If not, the characteristics of the assignment in the Plan will first have to be modified (procedure under Article 4 of the relevant agreement concerned). There is no assignment free in the Plan in question. You then have to initiate the plan modification procedure in order to add a new assignment (procedure under Article 4 of the relevant agreement). Before doing so, it will be necessary to find the appropriate frequency and see how it is likely to affect the existing Plan and vice versa. Then coordinate with adjacent countries before notifying the Bureau of the assignment. After that, wait for publication of the assignment in part B of the appropriate special section before issuing a license to the operator and completing the procedure for registration of the assignment in the MIFR by notifying it under Article 11 of the Radio Regulations.
