Conclusion While WiFi is and will be widely used for short-range wireless connection of end-user devices, WiMAX is the correct, efficient wireless solution for long-range connection of multiple sites such as providing internet connection to multiple homes or interconnection of multiple buildings in a large compound.

It would not be as fast as in these fixed applications, but expectations are for about 15 Mbps capacity in a 3 km cell coverage area. With WiMAX, users could really cut free from today's Internet access arrangements and be able to go online at broadband speeds, almost wherever they like from within a MetroZone. WiMAX could potentially be deployed in a variety of spectrum bands: 2.
WiMAX can satisfy a variety of access needs. Potential applications include extending broadband capabilities to bring them closer to subscribers, filling gaps in cable, DSL and T1 services, WiFi, and cellular backhaul, providing last meter access from fibre to the curb and giving service providers another cost-effective option for supporting broadband services.
WiMAX can support very high bandwidth solutions where large spectrum deployments i. WiMAX can help service providers meet many of the challenges they face due to increasing customer demands without discarding their existing infrastructure investments because it has the ability to seamlessly interoperate across various network types.
The biggest difference isn't speed; it's distance. WiFi's range is about feet 30 m. WiMAX will blanket a radius of 30 miles 50 km with wireless access. The increased range is due to the frequencies used and the power of the transmitter.
Of course, at that distance, terrain, weather and large buildings will act to reduce the maximum range in some circumstances, but the potential is there to cover huge tracts of land. Intel will start making their Centrino laptop processors WiMAX enabled in the next two to three years. This will go a long way toward making WiMAX a success. If everyone's laptop already has it which is predicted by , it will be much less risky for companies to set up WiMAX base stations.
Intel also announced that it would be partnering with a company called Clearwire to push WiMAX even further ahead.
Clearwire plans to send data from WiMAX base stations to small wireless modems. Who's going to pay for WiMAX? It depends how it will be used. There are two ways WiMAX can be implemented -- as a zone for wireless connections that single users go to when they want to connect to the Internet on a laptop the non-line-of-sight "super WiFi" implementation , or as a line-of-sight hub used to connect hundreds of customers to a steady, always-on, high-speed wireless Internet connection. Under the "super WiFi" plan, cities might pay to have WiMAX base stations set up in key areas for business and commerce and then allow people to use them for free.
They already do this with WiFi, but instead of putting in a bunch of WiFi hot spots that cover a few hundred square yards, a city could pay for one WiMAX base station and cover an entire financial district. This could provide a strong draw when city leaders try to attract businesses to their area. Some companies might set up WiMAX transmitters and then make people pay for access. Again, this is similar to strategies used for WiFi, but a much wider area would be covered. These companies might offer unlimited access for a monthly fee or a "pay as you go" plan that charges on a per-minute or per-hour basis.
The high-speed wireless hub plan has the potential to be far more revolutionary. If you have high-speed Internet access now, it probably works something like this: The cable or phone company has a line that runs into your home. That line goes to a cable modem, and another line runs from the modem to your computer.
