Worldwide interoperability for Microwave Access (WiMAX) is a wireless technology depending on IEEE 802.16 standard. A WiMAX cell which is to be taken into account in this study employs multicast mode of operation, the primary restriction of increasing the system capacity is the signal to noise ratio (subscribers near the base station employ 3/4 Reed Solomon code and 64 QAM, while those which are close the border of the cell employs ½ Reed Solomon code and PSK to pay for the S/N impact).
