ABSTRACT
WiMAX is an acronym that stands for Worldwide Interoperability for Microwave Access. WiMAX is a wireless metropolitan area network (MAN) technology that can connect IEEE 802.11 (Wi-Fi) hotspots with each other and to other parts of the Internet. It can provide a wireless alternative to cable and DSL for last mile (last km) broadband access. WiMAX is the wireless solution for the next step up in scale, the metropolitan area network (MAN). WiMax does not conflict with Wi-Fi but actually complements it. A WiMax system consists of two parts: A WiMax tower & A WiMax receiver. WiMAX has the potential to do to broadband Internet access what cell phones have done to phone access. Some cellular companies are also evaluating WiMAX as a means of increasing bandwidth for a variety of data-intensive applications. The purpose of this Paper is to highlight and assess the value of WiMAX as the right solution to:

• offers cheap voice calls and high speed internet
• ensures a boost for government security
• extend the currently limited coverage of public LAN (hotspots) to citywide coverage (hot zones) the same technology being usable at home and
on the move,
• blanket metropolitan areas for mobile data-centric
service delivery,
• offer fixed broadband access in urban
and suburban areas where copper quality
is poor or unbundling difficult,
• bridge the digital divide in low-density areas where technical and economic factors make broadband deployment very challenging. In addition to these uses, this paper will highlight other potential applications, such as telephony or an effective point-to-multipoint backhauling solution for operators or enterprises
1.INTRODUCTION
WiMAX is an acronym that stands for Worldwide Interoperability for Microwave Access, a certification mark for products that pass conformity and interoperability tests for the IEEE 802.16 standards.
Products that pass the conformity tests for WiMAX are capable of forming wireless connections between them to permit the carrying of internet packet data. It is similar to Wi-Fi in concept, but has certain improvements that are aimed at improving performance and should permit usage over much greater distances. the WiMAX forum, backed by industry leaders, will encourage the widespread adoption of broadband wireless access by establishing a brand for the technology and pushing
