WiMAX as a next generation wireless network

IEEE 802.16/Worldwide Interoperability for Microwave Access (WiMAX) technology is a very promising successor to the current wireless technologies like 3G, IEEE 802.11/WiFi. WiMAX incorporates a number of advanced techniques which make it stand apart from the current technologies. WiMAX has evolved quite a lot from the 802.16 standard which was approved in December, 2001. It now has different modes of operations and offers mobility support along with robust security measures. For this to be implemented fully, it has to overcome quite a number of challenges.
