WHAT IS WIMAX? Users today mostly use Broadband connections,Wi-Fi and cellular networks to access the Internet. WiMAX is IP based 4G technology wireless broadband access technology performance similar to Wi-Fi, with the coverage and QOS (quality of service) of cellular networks.o WiMAX=Worldwide Interoperability for Microwave Access
Based on IEEE 802.16 standard. Founded by Ensemble, CrossSpan, Harris & Nokia. Ensures compatibility and interoperability between broadband wireless access(BWA) equipment. Intended for WMAN(wireless MAN).
THE WIMAX FORUM The WiMAX Forum is a non profit organization formed to promote the adoption of WiMAX compatible products and services A major role for the organization is to certify the interoperability of WiMAX products. Another role of the WiMAX Forum is to promote the spread of knowledge about WiMAX.
o GOAL OF WiMAX To provide high speed Internet access to home and business subscribers, at a data rate of 30-40 Mbps, with the 2011 update providing upto 1 Gbps for fixed stationso COVERAGE RANGE OF WiMAX WiMAX can provide broadband wireless access (BWA) up to 30 miles (50 km) for fixed stations, and 3 - 10 miles (5 - 15 km) for mobile stations.
Wimax Technology OverviewConsists of:oBase StationoAccess PointoSubscriber Station. The data Traffic channels, which goes through the Base Station .Bandwidth Allocation for Radio Channel is done by Base Station.Types of Link are :Uplink (from Subscriber Station to Base Station )Downlink( Base Station to Subscriber Station )`
InfraStructure of Wimax TechnologyWimax Tower :Its looks like Normal cell Phone Towers.
Wimax Receiver:Receiver and Antenna looks like a Small Box.

Wifi needs effort to Wimax network provides Quality of stay connected with a Service(QoS). specified access point. It is a high cost It is a low cost network. network. It offers high speed of It offers short range broadband access of data transfer.
Why WiMAX over 3G?WiMax spectrum is more economical than 3G. The price paid per Hz is as much as 1000 times lower than for 3G spectrum !!
Uses of WiMAXThe bandwidth and range of WiMAX make it suitablefor the following potential applications:Providing portable mobile broadband connectivityacross cities and countries through a variety of devices.Providing a wireless alternative to cable and digitalsubscriber line (DSL) for "last mile" broadband access.Providing data, telecommunications (VoIP)and IPTV services (triple play).Providing a source of Internet connectivity as part ofa business continuity plan.Smart grids and metering
