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.
