Why WiMax.

This article discusses WiMax, an informal term that covers two emerging broadband wireless standards for metropolitan-area networking. WiMax promises alternate routes to land lines for disaster discovery and relief from the price and service tyranny of the incumbent local-exchange carriers. It has a compelling high-speed mobile component and describes by some as a high-quality broadband that mirrors connectivity experience in the office. There are two corresponding WiMax standards: (1) IEEE 802.16-2004 for fixed point-to-point and point-to-multipoint wireless access, and (2) IEEE 802.16e, for mobile wireless access from laptops and handheld.
