Impact of WARC-79 on the Studies of the International Radio Consultative Committee (CCIR)

The CCIR provided the main technical bases for the World Administrative Radio Conference, 1979, including terminology; technical bases for allocation, regulation, and for the provision for new services; characteristics of equipment and emissios; radio wave propagation and noise data. The WARC specified CCIR studies to be carried out for a number of future radio conferences to be held in the 1980-1986 time period, including a conference in 1983 to plan satellite broadcasting in the region of the Americas and a world conference in 1984/1986 concerning the geostationary satellite orbit. Additional studies set out for technical radio regulations included, for example, determination of coordination area around an Earth station in the bands from 1 to 40 GHz shared between space and terrestrial services, and other technical criteria for frequency band sharing. Over the next few years, because of the intense schedule of ITU administrative radio conferences, CCIR studies related to frequency sharing and other radio regulations will increase markedly.
