WiMax provides Broadband Access

WiMax is a wireless digital communications system that allows transmission of data in various ways, ranging from point-to-point links to full mobile cellular-type access.  WiMax provides broaband wireless access (BWA) up to 30 miles (50 km) for fixed (point to point) stations, and 3—10 miles (5—15 km) for mobile stations unlike WiFi/ 802.11 wireless local area network standard  where access is limited  to only 100 to 300 feet (30-100m).

WiMax  enables the delivery of last mile wireless broadband access, which is an alternative to cable and DSL.  Last mile connectivity refers to the final leg of delivering connectivity from a communications provider to a customer.  The WiMax broadband wireless access is believed to lower the prices of communication systems as it will create competition between service providers of DSL and cable. It is aimed at wireless mobile broadband for operations from 120 to 350 km/h.  It provides access to low density and rural areas.  It can be used as a point to multi-point broadband technology, providing individual users access to broadband services.  The WiMax broadband technology brings broadband services to areas where wired infrastructure is not yet available at present.

WiMax links the broadband access at home and in the office. WiMax broadband access can be fixed or mobile.  Fixed access refers to broadband service suited for delivering wireless last mile access for fixed broadband services, like the DSL or cable modem service.  Mobile access refers to broadband service, which supports both fixed and mobile applications that includes improved performance and capacity while adding full mobility.  Mobile access allows users to use the Internet everywhere they go and get connected even while using their mobile phone.
