Experimental Research of Signal Fading in Fixed Wireless Links

摘要

Two-year experimental research results of radio signal propagation and fading are presented in this paper. Microwave wireless links located in coastal and continental terrain and operated at 15 GHz were tested. The impacts of different atmosphere phenomena such as rain, brume, dew, weather, ground and dew point temperatures on the signal strength fading in these wireless links were assessed. Additionally, multipath effect origin and rain attenuation were analysed.
