What is WiMax?
WiMax is a radio technology that promises to deliver two-way Internet access at speeds of up to 75 Mbps at long range. WiMax, short for Worldwide Interoperability for Microwave Access, is the latest of the wireless "last mile" broadband technologies. Typically it can provide coverage for around 35 miles
Laying wires is especially difficult in hilly areas. Instead of that erecting a big antenna on a hill and installing antennas directed at it on customer’s roof’s in much easier than digging and stringing cables. Many people in the industry realized that having a broadband wireless standard was the key element missing, so IEEE was asked to form a committee to draw up the standard. The next available number in the 802 numbering space was 802.16, so the standard got this number.
Overall vision for 802.16 is that carriers (e.g., ISP) would set up base stations connected to a public network. Each base station would support hundreds of fixed subscriber stations. Fixed means that subscriber stations do not move. Plans to expand the standard to include mobile stations is in the working.
Base stations will use the 802.16 protocols to dynamically allocate uplink/downlink bandwidth to subscriber stations based on their demand. 802.16 has been developed for several frequency bands (various licensed frequencies in 10-66 GHz, also licensed and unlicensed frequencies in 2-11 GHz).
Some Technical Specs on WiMax
The radio technology is based on OFDM.
802.16 standards incorporate use of adaptive antenna arrays, which can be used to create dynamic beams in desired directions.
Standards offer option for a mesh mode network topology.
802.11 Vs 802.16
The environments in which 802.11 and 802.16 operate are similar, but they differ in major ways. 802.16 is designed to be wireless but stationary while 802.11 deals with mobility. 802.16 is a large range system, covering many km and making use of licensed and unlicensed spectrum. 802.11 is a short range system, typically hundreds of meters that uses unlicensed spectrum to provide access to the network.
