Performance Evaluation of Angular Separation on Cell Site Diversity Gain

Abstract

There have been remarkable advancements in the field of broadband wireless access (BFWA) technologies. These technologies operate in microwave frequencies where rain attenuation is the most important factor leading to signal impairments. The use of cell site diversity (CSD) can help in overcoming the signal fading. During the event of rain, when the signal level falls below a particular threshold, the subscriber station switches to another base station in the coverage area. The CSD gain bears strong correlation with the angular separation between the various base stations. This paper analyses the effects of CSD gain on angular separation.
