Abstract :
In satellite transmission at frequencies above 10 GHz, signal fading, and hence outage, is mainly attributed to rain. Annual and worst month cumulative statistics may not provide sufficient information to design services adequately in the tropics. Statistics of seasonal and diurnal fade variations will give the detailed insights required for direct-to-home/very small aperture terminals (DTH/VSAT) system designs in tropical climates subjected to heavy rain. Diurnal fading statistics for a wet, tropical location in Lae, Papua New Guinea, are presented
