Slant path attenuation measurements at 50 GHz in Spain

A one-year campaign of slant path attenuation measurements has been carried out in Madrid using the ITALSAT satellite beacon at 50 GHz. The experimental cumulative distributions of rainfall rate and rain attenuation are presented. The first one is compared with the ITU-R (International Telecommunication Union-Radiocommunication) maps while measured attenuation values are compared with several prediction models. Finally, the relationship between average year and worst month is investigated.
