Abstract

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.
