Dimensional statistics of rainfall signature and fade duration for microwave propagation in Nigeria

As the communication services are increasingly demanding more access for higher frequencies up to Ka-band and beyond, dimensional statistics of rainfall for predicting rain induced attenuation is required in order to estimate the link budget and the communication performance. Attenuation due to rain restricts the path length of radio communication systems and limits the usage of higher frequencies for terrestrial point-to-point microwave links and satellite communications. In this paper, some results of dimensional statistics of rainfall signature and fade duration are presented. Rain events are studied to examine the efficacy of predicting the slant-path attenuations from point rain rate measurements.
