WiMAX (Worldwide Interoperability for Microwave Access) is introduced by the Institute of Electrical and Electronic Engineers (IEEE) which is designated by 802.16. There are fixed (802.16d) and mobile (802.16e) WiMAX [1] which offers both line of sight and non-line of sight wireless connectivity. This technology offers a high speed, secure, sophisticate, last mile broadband service, ensuring a flexible and cheap solution to certain rural access zones. In a fixed wireless communication, WiMAX can replace the telephone company's copper wire networks, the cable TV's coaxial cable infrastructure.

In its mobile variant it can replace cellular networks. In comparison with Wi-Fi and Cellular technology, Wi-Fi provides a high data rate, but only on a short range of distances and with a slow movement of the user. And Cellular offers larger ranges and vehicular mobility, but it provides lower data rates, and requires high investments for its deployment. WiMAX tries to balance this situation. WiMAX fills the gap between Wi-Fi and Cellular, thus providing vehicular mobility, and high service areas and data rates WiMAX developments have been rapidly moving forward.
