How 802.11n backward compatibility works 07 February, 2006 13:46:30

It has been widely reported that 802.11n, the wireless LAN IEEE draft standard that uses multiple input/multiple output technology to boost Wi-Fi speeds to over 100Mbps, is "backward compatible" with today's 802.11a, 11b, and 11g networks. This can seem confusing, given that 802.11a, which runs in the 5-GHz frequency band, is not compatible with 802.11g and 11b, which operate in the 2.4-GHz band.
