3.6 COMETS Propagation Measurements For Land-Mobile Channels -Ka-Band And Millimeter-Wave Propagation Measurements in Sydney, Australia-

摘要

Ka-band and millimeter wave land-mobile satellite communications experiments using the Communi- cations 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 44GHz and medium-elevation-angle propagation characteristics at 23GHz were measured in central Sydney and in its suburbs. Indoor propagation characteristics at 23GHz were also evaluated in measurements carried out at the University of Technology, Sydney.
