Estimation of attenuation due to rain within Ka and Ku bands in Oyo State of Nigeria

Rain-induced attenuation of microwaves poses a serious challenge to signal availability beyond 10 GHz frequencies. The challenges are even more pronounced in the subtropical and tropical regions with high intensities rain which is accompanied thunderstorms. Nigeria has an equatorial climate, identified by controlling rainfall. Rain significant factor various communication above Therefore, for effective utilization microwave bandwidth during rainfall, it required form correlation between this effect at rainfall rate frequencies particular interest location. Therefore , using propagation modelling, point effects was concurrently considered 11 40 (i.e. Ku, Ka) satellite service on earth-space path Ibadan Oyo state data period five (5) years (January 2014 December 2019).Keywords- Attenuation, Rate, Bandwidth, Propagation Modelling
