WiMax Technology
WiMAX is expected to provide fixed , nomadic, portable and, eventually, mobile wireless broadband connectivity without the need for direct line-of-sight (LOS) with a base station.
In a typical cell radius deployment of three to ten kilometers, WiMAX Forum Certified™ systems can be expected 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 radius deployment of up to three kilometers.
Wi-Fi: The Predecessor of WiMax
Wi-Fi (Wireless Fidelity) is a set of technologies that are based on the IEEE 802.11a,b, and g standards.
Wi-Fi is considered to be one of the first widely deployed fixed broadband wireless networks.
The Wi-Fi architecture consists of a base station that wireless hosts connect to in order to access network resources.
As long as the users remain within 300 feet of the fixed wireless access point, they can maintain broadband wireless connectivity.
WiMax Spectrum
Broad Operating Range
WiMax Forum is focusing on 3 spectrum bands for global deployment:
Unlicensed 5 GHz: Includes bands between 5.25 and 5.85 GHz. In the upper 5 GHz band (5.725 – 5.850 GHz) many countries allow higher power output (4 Watts) that makes it attractive for WiMax applications.
Licensed 3.5 GHz: Bands between 3.4 and 3.6 GHz have been allocated for BWA in majority of countries.
Licensed 2.5 GHz: The bands between 2.5 and 2.6 GHz have been allocated in the US, Mexico, Brazil and in some SEA countries. In US this spectrum is licensed for MDS and ITFS.
Conclusions
It is expected that WiMax becomes the dominant standard for Wireless MAN in the world market, at least, in fixed broadband networks.
WiMax products will have to be delivered to the market needs and those for the end-users will have to be extremely easy to install.
Focus is too often on technologies
– Subscribers pay for services, not technologies
– Technologies enable services, but should not be a burden on users
– Broadband capabilities are important, but bandwidth is not the only meter to assess service
