WiMAX network performance improvement with OFDM-MIMO technology

Current 3G WCDMA cellular systems enjoy great acceptance but the rate of data transmission is rapidly nearing its limits. User demand for ever greater data needs thanks to services like Video and PC like web site browsing is taxing the system to their limits. The wireless channel doesn't help things either; it is a very hostile transmission environment. Developments in the WiMAX standard have the potential to mitigate the data transmission problem. It has provisions for transmitting using MIMO antennas, Adaptive Modulation and Coding and higher data rate. Current 3G WCDMA transmission top out at 14.4 Mbps in ideal conditions. WiMAX has the potential for up to 70 Mbps transmission rate and more robust transmission link between base station and mobile station. The proposed solution can be used to increase data throughput and reliability without the need to increase antenna locations and bandwidth.
