WIMAX is wireless broadband access technology that provides performance similar to 802.11/Wi-Fi networks. it is based on IP. It stands for Worldwide Interoperability for Microwave Access (WiMAX).

It is a wireless digital communication system, It is famous as IEEE 802.16 standard. Basically it works for "metropolitan area networks". WiMax has the ability to provide broadband wireless access(BWA) till 30 miles(50 Km) for fixed stations and about 3-10 miles for mobile stations. Contrary to which, the WiFi/802.11 WLan standard is limited in most of the cases to only 100-300 feet i.e. (30-100 m).



Due to itís high security, robustness and mainly huge data rates is soon to replace/support existing wireless access
technologies like Wifi, Bluetooth, etc and thus believed to be the next generation of wireless access technology. When commercially available, Wimax will offer fixed, nomadic and mobile wireless broadband connectivity without needing direct line-of-sight access to a base station.
