WiMAX or Worldwide Interoperability for Microwave Access, based on the IEEE 802.16 standard, is expected to enable true broadband speeds over wireless networks at a cost point to enable mass market adoption. WiMAX is the only wireless standard today that has the ability to deliver true broadband speeds and help make the vision of pervasive connectivity a reality.There are two main applications of WiMAX today: fixed WiMAX applications are point-to-multipoint enabling broadband access to homes and businesses, whereas mobile WiMAX offers the full mobility of cellular networks at true broadband speeds. Both fixed and mobile applications of WiMAX are engineered to help deliver ubiquitous, high-throughput broadband wireless services at a low cost.It has emerged as the most promising wide-area wireless broadband technology in a short span of time. The technology is being adopted in a number of markets and is poised for dramatic growth in India as well. As it can cover relatively long distances, WiMAX has the potential to serve everything from low-density residential applications to enterprise customers. Many companies are closely examining WiMAX for "last mile" connectivity at high data rates. This could result in lower pricing for both home and business customers as competition lowers prices.
