Outage Performance of Single/dual Polarized Fixed Wireless Access Links in Heavy Rain Climatic Regions

The outage performance of line-of-sight fixed wireless access channels operating above 10 GHz is predominantly controlled by rain attenuation. In this paper, a prediction model, appropriate for heavy rain climatic regions based on gamma distribution assumption for the rainfall rate and the rain attenuation is being reviewed to incorporate the recently released ITU-R rainmaps. The model exhibits a very good performance, as validated by tests against the ITU-R databank Moreover, the above model is extended to evaluate the outage performance of a dual-polarized mm-wave fixed wireless access link located in heavy rain climatic regions. The obtained numerical results focus on the investigation of the effects of various operational parameters upon the outage performance of the microwave communication link.
