H. Wakana et al., Fade characteristics for K-band land-mobile satellite channels in Tokyo measured using COMETS, ELECTR LETT, 35(22), 1999, pp. 1912-1913
The K-band fade statistics in Tokyo were measured using an antenna (beamwid
th of 19.5 degrees in elevation and 6.5 degrees in azimuth) at elevations r
anging from 37 to 80 degrees. The results show that line-of-sight communica
tion is possible only similar to 33% of the distance at elevations < 50 deg
rees, but it is 98% at 80 degrees.
