An enhancement to the IEEE 802.11 wireless network standard that increases transmission speeds to 108 Mbps and beyond.
Expected in the 2006 time frame, there are two competing technologies, although both of them are MIMO based, which uses multiple transmitters and receivers.
The WorldWide Spectrum Efficiency (WWiSE) group wants to stay in the 2.4GHz band and use the same 20MHz channels as 802.11b and 11g for compatibility. Task Group n (TGn) wants to use the 5GHz band like 802.11a and boost channel width to 40MHz to increase the data rate. See MIMO and 802.11.
