The Effect of Rain Attenuation on the Performance of BFWA around Kjeller, Norway

In this contribution we study the effect of rain attenuation on the performance of broadband fixed wireless access (BFWA) around Kjeller, Norway. The analysis was performed using rain attenuation statistics derived from local measurements at 42 GHz collected over 4 years from a star-like network. The rain attenuation statistics of three converging links is presented and has been compared with the ITU-R model. Generally, the ITU-R model predicts the rain attenuation statistics relatively well, except for high attenuation ranges where the model overestimates the occurrence. In addition, statistical results of the channel capacity and bit error rate (BER) in the presence of rain attenuation at different service distances in scenarios with and without intercell interference are presented. Generally, the results give an insight to the effect of rain attenuation, and may allow service providers in evaluating the technical feasibility of BFWA systems in locations with weather conditions similar to Kjeller area.
