What is WiMax? WiMax (Worldwide Interoperability for

Microwave Access) is a standards-based

technology enabling the delivery of lastmile wireless broadband access as analternative to cable and DSL.

The technology is specified by the Instituteof Electrical and Electronics Engineers Inc.,as the IEEE 802.16 standard.

WiMax Technology WiMAX is expected to provide fixed , nomadic, portable

and, eventually, mobile wireless broadbandconnectivity without the need for direct line-of-sight(LOS) with a base station.

In a typical cell radius deployment of three to tenkilometers, WiMAX Forum Certified systems can beexpected to deliver capacity of up to 40 Mbps per

channel, for fixed and portable access applications. Mobile network deployments are expected to provide

up to 15 Mbps of capacity within a typical cell radiusdeployment of up to three kilometers.

How WiMax Works WiMax can provide 2 forms of wireless service:

- Non-LOS, Wi-Fi sort of service, where a small antenna ona computer connects to the tower. Uses lower frequency

range (2 to 11 GHz).- LOS, where a fixed antenna points straight at the WiMaxtower from a rooftop or pole. The LOS connection isstronger and more stable, so it is able to send a lot of datawith fewer errors. Uses higher frequencies, with ranges

reaching a possible 66 GHz. Through stronger LOS antennas, WiMax transmitting

stations would send data to WiMax enabled computers orrouters set up within 30 (3,600 square miles of coverage)

mile radius.

WiMax Rollout WiMax Forum anticipates rollout of its

technology in 3 phases:

- Phase 1: Fixed Location, Private LineServices, Hot Spot Backhaul.

- Phase 2: Broadband WirelessAccess/Wireless DSL

- Phase 3: Mobile/Nomadic Users.

WiMax Applications According to WiMax Forum it supports

5 classes of applications:

1. Multi-player Interactive Gaming.

2. VOIP and Video Conference

3. Streaming Media

4. Web Browsing and Instant Messaging

5. Media Content Downloads

WiMax Success Factors It is crucial that WiMax becomes an important

building block to enable fixed/mobile convergenceand to ensure its success.

Ability to offer ease of use is crucial to the successof WiMAX service providers

Success of WiMAX may depend on the ability to

combine fixed and mobile access over the sameinfrastructure.
