Title: Study of attenuation caused by rain for the development of future radio technologies
Keywords: ITU Model, Millimeter Waves, Rain AttenuationRainfall Rate, Satellite Communication
Abstract: The availability is the key performance matrix for the satellite communication system. There are various factors which affect the availability of links like hardware reliability, fading, interference etc. Attenuation caused by hydrometeors specially rain plays an significant role when dealing with frequencies above 10 GHz. Various models have been proposed in this regards but ITU-R model for rain attenuation is acceptable worldwide. This paper describe about the major problems faced by researchers while using ITU-R rain model then the approximations for the coefficients for both horizontal and vertical polarization has been performed. Equations are derived from the approximations. The approximation rain model is compared with the ITU rain model.
