Abstract
Ka-band and millimeter-wave land-mobile satellite communications experiments using the Communications and Broadcasting Engineering Test Satellite (COMETS) were carried out in Sydney from 10 March to 29 March 1999. High-elevation-angle propagation characteristics at 21 GHz and 44 GHz, and medium-elevation-angle propagation characteristics at 23 GHz were measured in central Sydney and in its suburbs. Land-mobile satellite services at high elevation angles of 74 degrees to 81 degrees can be provided over more than 94% of central Sydney, but the availability at elevation angles of 40 degrees to 50 degrees, which correspond to those for geostationary satellites, is only 19% to 26%. The experimental results showed that both Ka-band and millimeter-wave bands are useful for land-mobile satellite communications in sub-urban and rural areas, but only at high elevation angles in urban areas.
