In the new era of communication, WiMAX (IEEE 802.16) is the most emerging technology that enables ubiquitous delivery of broadband wireless access for fixed and mobile users. It is a more innovative and commercially viable alternative to cable modems and DSL technologies as it is cost effective, easy to implement, high performance and high resource utilization technology. This economic environment has led to the development of the IEEE 802.16 standards to support broadband wireless multi-service access in metropolitan area. In addition, the Worldwide interoperability for Microwave Access (WiMAX) Forum has been formed which promotes the technology and provides compatibility and interoperability for 802.16 -based products. Accordingly, the term WiMAX is often used interchangeably with IEEE 802.16 technologies. WiMAX a wireless standard which uses Orthogonal Frequency Division Multiple Access (OFDMA) and promises to offer mobile broadband services even at a vehicular speed of up to 120 km/h.
