The development of 802.16 standards for Broadband Wireless Access technologies (BWA) was motivated by the rapidly growing need for high-speed, ubiquitous and cost-effective access. The limitations of conventional broadband wireless access have been overcome with the scalable features of WiMAX. WiMAX is Worldwide interoperability for Microwave Access. It is one of the wireless communication technologies, especially Broadband Wireless Access (BWA) which uses OFDM (Orthogonal Frequency Division Multiplexing) and MIMO (Multiple Input Multiple Output) systems in order to provide high data rates, minimization of bandwidth and fading effects.
