ABSTRACT
A wireless revolution is seeping into our daily lives never before. Sooner or later we are all going to go wireless. Broadband Wireless Access has occupied a niche in the market for about a decade. The recently developed Blue tooth wireless technology is a low power, short-range technology for ‘ad hoc’ cable replacement and it enables people to wirelessly combine devices wherever they bring them. Due to the short-range limitations of Blue tooth, the recent emergence of Wifi has replaced it. Wifi popularly known as 802.11 is a moderate–range, moderate–speed technology based on Ethernet. It allows people to wirelessly access throughout a location. Although the technologies share a 2.4GHz band, they have potentially overlapping applications. As more and more people use Wifi, more and more people are getting frustrated with its coverage limitations. The demand for more coverage has opened a door for WiMax.
WiMax built on IEEE 802.16 standards is a wireless technology that provides high throughput broadband connections over long distances .Due to it’s 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.
WiMAX is a coined term or acronym meaning Worldwide Interoperability For Microwave Access (WiMAX). Its purpose is to ensure that the broadband wireless radios manufactured for customer use interoperate from vendor to vendor. WiMax is a new standard being developed by the IEEE that focuses on solving the problems of point to multipoint broadband outdoor wireless networks. It has several possible applications, including last mile connectivity for homes and businesses and backhaul for wireless hot spots.
While WiMax has historically lacked the grass roots popularity of its popular cousin, WiFi, and is the standard for wireless metropolitan area networks (WMANs). It has gained significant traction from the high profile support it has received from the likes of Intel, Dell, Motorola, Fujitsu and other big name corporations. It represents the next generation of wireless networking. Intel has called it as a technology that will enable up to 5 billion people to be connected over time.
WiMAX is both faster and has a longer range than Wi-Fi. However, WiMAX does not necessarily conflict with Wi-Fi, but is designed to co-exist with it and may indeed complement it. This complementarity to Wi-Fi also extends to all flavors of wired ethernet (IEEE 802.3), token ring (IEEE 802.5) and non-IEEE Standards .
