Abstract :
Personal communications will be supported in metropolitan areas using terrestrial-based transmission means and the L-band portion of the frequency spectrum. On the other hand, satellite communications´ global coverage makes it attractive to provide service to remote areas. The Ka-band offers several advantages to support such services, notably the abundance of available spectrum. The limitations of a class of earth terminals, including handheld units, operating at Ka-band are explored. These limitations include service availability (effect of rain), radiation hazards, call notification and antenna pointing. It is shown that satellite handheld communicators are feasible if certain operating constraints are accepted. Finally the characteristics of the satellite and the multiple access techniques suitable for providing this service are described
