Spectrum aspects of personal communication systems

The spectrum aspects of terrestrial personal communication systems (PCSs) are discussed. A total of at least 230 MHz is required between 1 and 3 GHz. This consists of 60 MHz for low-power access and 170 MHz for high-power access. It is desirable that the spectrum for satellite access be adjacent to that for terrestrial access. To maximize the benefits of economies of scale and the forces of competition, and also to meet the needs of global travelers, a minimum of 60 MHz of worldwide allocation is required. The PCS spectrum should be made available below 3 GHz by around 1997
