摘要:Attenuation due to rain is an important constraint in the designing of the microwave
communications links operating in Malaysia especially at frequencies above 10 GHz. In
recent studies, the ITU-R proposed models for the prediction of rain attenuation give a good
estimation for the microwave propagation loss caused by rain for the temperate regions but
it underestimates the rain attenuation prediction for the tropical regions. This paper studies
the rain attenuation prediction models for the design of microwave terrestrial line-of-sight
(LOS) systems and the results of this investigation.
