Rain attenuation variability calculated from a slant-path Ka-band experiment

This study is based on the results of a slant-path Ka-band propagation experiment carried out in Madrid, Spain, regarding rain attenuation, which is the main propagation impairment in this frequency band. The experimental and statistical results correspond to seven complete years of measurements, a period large enough to accomplish a comprehensive analysis in order to characterize the variability of rain rate and attenuation. Variability is assessed on the basis of annual, seasonal, and worst-month distributions.
