International Radio Consultative Committee
Comité consultatif international des radiocommunications (CCIR)
Comité Consultivo Internacional de Radiocomunicaciones
18 Nov 1927, Washington DC (USA), as Comité consultatif international technique des communications radioélectriques. Legal status of CCIR established under Article 11 of International Telecommunication Convention, 1982, signed 6 Nov 1982, Nairobi (Kenya), and entered into force 1 Jan 1984, superseding International Telecommunication Convention, 1973, signed 25 Oct 1973, Malaga-Torremolinos (Spain), entered into force 1 Jan 1975. One of the permanent organs of International Telecommunication Union (ITU), together with: ITU General Secretariat; International Telegraph and Telephone Consultative Committee (CCITT), formed 1956, Geneva (Switzerland). Statutes registered in 'LNTS 1/1905'. Ceased to exist when merged, 1 Mar 1993, with International Frequency Registration Board (IFRB), set up 1947, Atlantic City NJ (USA), to form 'Radiocommunication Sector (ITU-R)' of ITU, administered by ITU Radiocommunication Bureau (BR).
Study technical radio and operating questions relating specifically to radiocommunication, without limit of frequency range, and issue recommendations on them.Available with paid subscription only.
Responsible for technical and administrative support of ITU 'World and Regional Radiocommunication Conferences', 'Radio Regulations', 'Radiocommunication Assemblies and Study Groups'. Bureau carries out 'International Regulatory Processes' for registration of frequency assignments and satellite orbits, and assists in solving cases of harmful interference. Director serves as Executive Secretary of the Radio Regulations Board. The Bureau also provides 'Specialized Technical Secretariat' for the work of Radiocommunication Study Groups and Assembly in developing recommendations for spectrum utilization and radio system characteristics, and technical information and seminars for national frequency management and radiocommunications, working closely with the Telecommunications Development Bureau in matters for developing countries.
'Space Services Department' carries out space system and earth station coordination, examination and recording; examines space-related frequency assignment notices; assists administrations in frequency management and coordination concerning space radiocommunications. 'Terrestrial services Department' processes notices for terrestrial services, except in bands shared with space services, covering LF, MF, HF, VHF and UHF parts of the spectrum, fixed and mobile services such as radio relays, maritime and aeronautical services, and other services concerning radionavigation, standard frequency and time signal and meteorology; assists administrations on frequency selection, application of procedures and treatment of harmful interference cases; organizes and analyses results of regular monitoring programmes; coordinates and prepares publications. 'Radio Communication Information Systems Department' develops and maintains software and user support for systems within and outside the Bureau. Systems: Frequency Management System; Master International Frequency Register; Space Network System.
'Radiocommunication Study Groups' comprise 1,500 specialists world wide dealing with different services, radiowave propagation and use of frequency spectrum/geostationary orbit according to a programme set by the Radiocommunication Assembly. 'ITU-R' Recommendations, prepared by working parties and task groups, are approved by correspondence following unanimous acceptance by the relevant Study Group or by the Assembly. Study Groups A (4): Spectrum management techniques; Science services; Broadcasting services (sound and television); Inter-service sharing and compatibility. Study Groups B (4): Fixed-satellite service; Fixed service; Mobile, radiodetermination and amateur services; Radiowave propagation. Conference Preparatory Group carries out studies and prepares reports for 'World Radiocommunication Conferences' (every 2 years) and for 'Regional Radiocommunication Conferences'.
ITU seminars/workshops on frequency management and radiocommunication systems (twice a year); regional seminars and workshops as required in developing regions, in cooperation with Telecommunication Development Bureau.
