    There are two major elements of a General World Administrative Radio Conference such as WARC-79. One is to review and revise allocations of radio frequencies to functional services such as fixed, mobile, satellite, and radionavigation. The other major element is the detailed radio regulations concerning use of these allocations by member Administrations. These regulations combine technical, econom... View full abstract»

  • The Canadian Approach to the Development of Communications by Satellite in the 12-GHz Band

    Publication Year: 1981, Page(s):290 - 296
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1344 KB)

    WARC-79 made significant changes to how the 12-GHz band will be used in Region 2. In particular, it decided that the 12-GHz band in Region 2 will extend upwards the 12.7 GHz, and that the upper portion of the overall band (11.7 to 12.7 GHz), will be planned at the 1983 Regional Conference. The paper describes these allocation changes and how satellite systems are being developed in Canada under th... View full abstract»
