The study of radio wave propagation for worst-month rain attenuation statistics in Malaysia

Abstract

The attenuation due to rain will pose a greater problem to communications as the frequency of occurrence of heavy rain increases. The annual worst-month statistics is an important tool for the design of reliable communication systems. Average annual statistics can be very misleading because rain attenuation outages are concentrated in a few months of the year at most locations. In a tropical region, like Malaysia, where excessive rainfall is a common phenomenon throughout the year, the knowledge of the worst-month rainfall statistics is required for the design of any reliable terrestrial and earth space communication link. A study of the worst-month rainfall rate and rain attenuation statistics for the Malaysian tropical climate will be presented in this chapter based on rain rate and rain attenuation data collected for 1 year period at UTM Skudai campus.
