Accurate prediction of rain attenuation is critical for the design terrestrial line-of-sight link systems above 5 GHz, particularly millimetre-wave frequency. Anomalous behaviour in adjustment factor existing models significantly greater than 1 at short distances and has been reported. To solve this problem improve accuracy, a model links proposed. The total described accounts contributions wet...

In this study, wepropose a new method for detecting wet periods by using telecommunicationsCommercial Microwave Links (CML). The purpose of the study is to automaticallyfind rain time slots. attenuation microwave signal, propagatingbetween transmitting antenna and receiving one, due variations ofthe climatic conditions over link, non-stationary signal. When rainevent occurs CML, signal level in...
