THEME – WIRELESS SYSTEMS TOPIC - WIMAX

Abstract:

While many technologies currently available, fixed broadband wireless can only provide line of sight (LOS) coverage; the technology behind WiMAX has been optimized to provide excellent non line of sight (NLOS) coverage. WiMAX, short for ‘Worldwide Interoperability for Microwave Access,’ refers to any broadband wireless access network based on the new IEEE 802.16 standard. WiMAX operates on the same general principles as WiFi -- it sends data from one computer to another via radio signals. WiMAX’s advanced technology provides the best of both worlds –large coverage distances of up to 50 kilometers under LOS conditions and typical cell radii of up to 5-miles/8 km under NLOS conditions. A computer (either a desktop or a laptop) equipped with WiMAX would receive data from the WiMAX transmitting station, probably using encrypted data keys to prevent unauthorized users from stealing access. WiMAX is able to transmit up to 70 megabits per second under optimal conditions. WiMAX can be used for a number of applications, including "last mile" broadband connections, hotspots and cellular backhaul, and high-speed enterprise connectivity for business. It’s possible that WiMAX could threaten 3G or other wide-area cellular technologies by speeding up the dissemination of cheap WiFi hot-spot service on ubiquitous citywide levels. But one thing is certain - WiMAX will replace WiFi.
