WiMax

(802.16a)

WiMax is the trade name for a family of new technologies related to the IEEE 802.16 wireless standards.

WiMax has the potential for very long range (5 - 30 miles) and high speeds.

The initial version, based on 802.16a, is designed for fixed (non-mobile) applications only, such as a wireless replacement for home DSL or cable modem service.

Newer versions, such as 802.16e, add support for mobility, potentially making WiMax a competitor for certain 3G or 4G cell-phone technologies.

WiMax uses OFDM (Orthogonal Frequency Division Multiplexing), an increasingly common type of digital wireless technology that is also used in some digital radio and television standards.

WiMax operates at higher frequencies than mobile phone networks. WiMax technology can operate in the 2.5 or 3.5 GHz licensed bands, or in the 5.8 GHz unlicensed band.
