An evergreen listening radio spectrum WiMAX informs that future demands must be met using more data throughput wireless technologies. Since WiMAX bandwidth is limited and user request goes on to grow. This problem could be solved by WiMAX (Worldwide interoperability for Microwave Access) technology. WiMAX is proposed by the Institute of Electrical and Electronic Engineers (IEEE) which is standard designated 802.16d-2004 (used in fixed wireless applications) and 802.16e-2005 (mobile wireless) to provide a worldwide interoperability for microwave access.
