A Model for Wimax Coverage & Capacity Performance Estimation

A new model for WiMAX coverage and capacity performances evaluation is presented in this paper. This model is capable to simply estimate performances on downlink radio channel (from base station to user terminal equipment), assuming that all users generate the same amount of traffic and that they are uniformly spread over the cell area. This paper presents also results from a WiMAX trial carried out in 3.5 GHz band. One of the trial objectives was to assess Erceg propagation model reliability in this frequency band. The result is that Erceg model can be used for performance evaluation at this stage. Simulation results using the proposed model, with Erceg propagation model, show good performances for a WiMAX system.
