IEEE 802.11n
Part of the IEEE 802.11 family of wireless local area network specifications, the IEEE 802.11n task group define modifications to the Physical and MAC layers in order to deliver 100Mbps data rates (operating at 2.4GHz or 5GHz frequency). The working group put forward a number of enhancements to achieve these higher data rates including support for MIMO and the use of two adjacent 20MHz channels. Equipment complying with the 802.11n standard is also backward compatible with the earlier 802.11a , 802.11b and 802.11g variants.
