Wimax Capacity Estimation through Different Channel Characteristic

In this paper we study the factors influencing system bandwidth capacity in IEEE 802.16e networks. Additionally, we investigate and evaluate the system capacity of 802.16j in order to understand how the relay architecture can lead to capacity increases in the downlink. An analytical study of the WiMAX propagation channel by using Cost-231 Hata Model is presented. This model performed in different frequency bands; the Signal to Noise Ratio (SNR) is achieved under different frequency band as well. The useful bandwidth for WiMAX in the downlink helped us calculate the maximum numbers of subscriber station (SS) based on traffic modeling. Numerical results and discussion highlight the effect of factors over WiMAX capacity; we also simulated the modeling for different system parameters and traffic cases to ease the mobile WiMAX planning using MATLAB.
