Abstract

For terrestrial microwave links operating at frequencies higher than 10 GHz, rain-induced degradations are significant. Major degradations caused by rain that affect the reliability and availability of terrestrial links are rain attenuation and rain fade. In researches to determine rain attenuation, receive signal of a terrestrial link is sampled to an integration time of one minute. Besides attenuation, rain fade is another major factor affecting the performance of microwave links. Rain fade is the dynamic fluctuation of receive signal due to inhomogeneities of the signal path, ranging from a few seconds to a few minutes. Rain fade provides additional information on understanding the characteristics of rain-induced degradations. In this chapter, analysis is focusing on rain fade slope and rain fade depth. Besides that, the relationship between fade slope to fall time and recovery time is discussed. The additional impact due to superposition of fade depth and attenuated signal is also discussed.
