It is important to mention here that Rain and Cloud related work in relation to Radio wave propagation over Nepal has not been carried out and therefore statistical effects are relatively unknown. There is need to improve prediction results in rain attenuation in order to achieve reliable wireless communication systems. Existing models require improvements or we need fresh approaches. It is therefore very important when planning both microwave and terrestrial line-of-sight system links; to make an accurate prediction of rain induced attenuation on propagation paths.

It is important to mention here that Rain and Cloud related work in relation to Radio wave propagation over Nepal has not been carried out and therefore statistical effects are relatively unknown. There is need to improve prediction results in rain attenuation in order to achieve reliable wireless communication systems. Existing models require improvements or we need fresh approaches. It is therefore very important when planning both microwave and terrestrial line-of-sight system links; to make an accurate prediction of rain induced attenuation on propagation paths. Rain rate and rain attenuation predictions are one of the vital steps to be considered when analyzing a microwave satellite communication links at the Ku and Ka bands.Atmospheric effects play a major role in the design of satellite- to-earth links operating at frequencies above 10GHz. Raindrops absorb and scatter radio waves, leading to signal attenuation and reduction of the system availability and reliability. The severity of rain impairment increases with frequency and varies with regional locations.
