Abstract	In a BFWA (broadband fixed wireless access network) the evolved SINR (signal to interference plus noise ratio) is relevant influenced by the TS (terminal station) to BS (base station) assignment. At the applied 38 GHz frequency band besides the existing interference and noise, the precipitation causes the greatest problem. A time-dependent rain event can cause SINR fluctuation, and that can result in termination of the radio links. If the communication link between TS and its serving BS is affected with heavy rain, a possible solution could be to assign these TS to another BS (route diversity). This method improves the SINR condition for the effected TS, however can lead to SINR degradation in other locations of BFWA serving area. Therefore a special TS-BS assignment criterion must be evaluated to improve the overall SlNR conditions in the whole BFWA area. In this paper the efficiency of the proposed dynamic route diversity method is presented and the attenuation effects of simple obstacles are also taken into account
