Wireless Protocol 802.11n Approaching Final Approval

July 21, 2009

(ChattahBox) — The wireless industry is really to roll out IEEE 802.11n. Matthew Gast, chief strategist in the office of the Chief Technology Officer, has announced on his blog that the final vote to ratify 802.11n could take place as early as September 11, 2009. It has taken exactly seven years to specify and approve 802.11n.

The 802.11 family includes the 802.11b and 802.11g protocols, which use the 2.4 GHz ISM band. Because of this choice of frequency band, 802.11b and g equipment may occasionally suffer interference from microwave ovens, cordless telephones and Bluetooth devices. 802.11n is a new multi-streaming modulation technique which improves upon the previous 802.11 standards by adding multiple-input multiple-output (MIMO) and many other newer features. While it is still under draft development, but products based on its proprietary pre-draft versions are being sold.
