Abstract :
Measured data of rain attenuation from 19 terrestrial line-of-sight links, operating in frequencies from 14.5 to 83.5 GHz, were analysed to provide statistics of fade durations as a function of the attenuation threshold. From these results, an empirical method for predicting outage intensity owing to rain attenuation was derived, that shows good agreement with the measurements and allows the calculations of required link margins.
