Coverage Vs throughput challenges in Mobile WiMAX

WiMAX (world interoperability for microwave access) continues its development to achieve high capacity services with large cell coverage. Although, users at the cell border achieves only poor signal to interference plus noise ratio (SINR) conditions due to the high amount of interference from neighboring cells. In Egypt the 3.5 GHz band is expected to be used for the IEEE 802.16e mobile WiMAX networks because the band is licensed and interference is under control. Furthermore, higher transmission powers are allowed and a better range and coverage than at 5.8 GHz can be obtained. Therefore we will discuss in this paper the challenges facing coverage vs throughput for the SUI channel model performed at 3500 MHz at the city of Alexandria, Egypt through statistical analysis and real-time simulation software to discover the effects of channel characteristics, channel model and forward error correction techniques when designing and planning a mobile WiMAX network.
