Rain Attenuation Analysis from System Operating at Ku and Ka Frequencies Bands

This study presents rain attenuation analysis from System operating at Ku and Ka Frequencies Bands. Focused to determine the effects of weather conditions on propagation link performance property and quality of service render to customers. Recently, there is high demand of data rate, voice and video information have being on the increase due to industrial evolution and technological advancements. Satellite communication systems have witnessed various impairments which are considered in this study. Basic climate data were obtained from Meteorological Centre in Nigeria, for three years duration (from January 2013 to December 2015). Four geographical locations, Abuja, Benin City, Kano and Warri were considered in this study, in Nigeria. It is observed that Warri witnessed the highest rainfall followed by Benin City, Abuja and lastly by Kano. It is observed that the month of August witnessed the highest rainfall per each month followed by September and July at the year 2015. It was observed that rainfall distribution pattern possess a non–linear distribution pattern. Therefore, Empirical modelling was deployed; using excels software to determine the rainfall pattern. Based on the analysis, it was observed that rainfall followed exponential distribution pattern of rainfall. The basic parameters used in rain attenuation were highlighted with the corresponding attenuation characteristics such has rain intensity, rain height, effective path length, specific attenuation, rainy path length, slang path and horizontal projection specific attenuation were determined
