摘要：
Communication systems operating at frequencies above 10 GHz in equatorial climates are subjected to many fade occurrences due to heavy rain. Rain rate analysis using 1- minute data for 10 years ( 1996 - 2006) measurements in Penang shows that the rain exceeded 126.8mm/ h for 0.01% of a year ( R-0.01). Simultaneous measurements of Ku- band rain attenuation give A(0.01) as 22 dB. The rain rate and attenuation are characterized by the presence of breakpoints in the respective exceedance curves. The attenuation exceeds the fade margin for about 8.8 hours in a year.
