MOBILE SERVICES ABOVE 1 GHZ (RADIO COMMUNICATIONS)

The present status of frequency allocation for mobile radio services, decisions of the 1979 World Administrative Radio Conference (WARC-79) relative to new and revised allocations above 1 GHz, and the future outlook are reviewed. Above 1 GHz, there are presently no allocations to the individual terrestrial mobile services (aeronautical, land, maritime). The main effort on satellite use for mobile services is below 2 GHz. As a result of WARC-79, there will be a significant increase in primary shared use of frequencies above 1 GHz by terrestrial mobile services (except aeronautical). The conference decided on a 6.5 MHz increase for maritime mobile-satellite service, and an additional 5 MHz for ship-to-shore high-speed data. Aeronautical mobile-satellite service has been delayed, while land mobile-satellite service is beginning to accelerate. An area receiving maximum attention is the possible use of emergency position-indicating radio beacons via satellite. The 1982 Mobile Conference will permit changes in the Radio Regulations to improve communications related to the rescue of ships and aircraft in distress; the 1986 conference will be broader in scope. Success of a land mobile-satellite system depends on economic viability.
