802.11n
Last modified: Monday, April 18, 2005 

In January 2004 IEEE announced that it will develop a new standard for wide-area wireless networks. The real speed would be 100 Mbit/s (even 250 Mbit/s in PHY level), and so up to 4-5 times faster than 802.11g, and perhaps 50 times faster than 802.11b. As projected, 802.11n will also offer a better operating distance than current networks. The standardization progress is expected to be completed by the end of 2006.

802.11n builds upon previous 802.11 standards by adding MIMO (multiple-input multiple-output). The additional transmitter and receiver antennas allow for increased data throughput through spatial multiplexing and increased range by exploiting the spatial diversity through coding schemes like Alamouti coding.
