Impact of hydrometeors on attenuation on parallel terrestrial paths at 58 GHz and 93 GHz

The results of one year of experimental research of attenuation due to hydrometeors at 58 GHz and 93 GHz parallel terrestrial paths are given. The cumulative distribution of rain intensities, the cumulative distributions of attenuation due to all hydrometeors together and the cumulative distributions of attenuation due to individual hydrometeors are presented. The influence of individual hydrometeors on attenuation is analysed. The obtained cumulative distribution of attenuation due to rain only is compared with the calculated one in accordance with the relevant ITU-R recommendation. The results obtained are used to assess the availability performances of both radio systems.
