Based on the IEEE 802.16 standard, WiMax allows delivery of wireless broadband services anytime, anywhere. It enables the delivery of last mile wireless broadband access, which will alter the wired broadband such as cable and DSL.
WiMax technology provides fixed, nomadic, portable and mobile wireless broadband connectivity that is Non-Line of Sight with the base station. It can deploy a cell radius pf 3-10 kms with a 40 Mbps per channel capacity for fixed and portable access applications. It has a bandwidth enough to provide T-1 speed connectivity to businesses and residences. The WiMax technology has been incorporated in notebook computers and PDAs thus delivering high-speed mobile Internet services anytime, anywhere.
Some of the key elements of WiMax technology include:
1. Lower Cost. It has a standard based platform that brings down costs and as it delivers volume economics to WiMax equipment.
2. Wider Coverage. It has optimized its services to provide excellent non-line of sight coverage. The Non-line of sight allows wider area coverage, better predictability of coverage and lower cost as fewer base stations and backhaul will be used, simple RF planning, shorter towers and faster CPE time installation.
3. Higher Capacity. WiMax technology uses the Orthogonal Frequency Division Multiplexing (OFDM) that delivers higher spectral efficiency, which in return provides higher data rate and overall system capacity.
4. Use of Standard Models, Which Maybe Fixed to Mobile. The new WiMax technology supports higher speed of mobility. It is designed to be the most cost effective solution for carriers for any usage model from fixed to mobile.
