802.11: The IEEE Committee responsible for setting wireless LAN standards. The 802.11 standard defines some aspects of frequency hopping and direct sequence spread spectrum systems for use in the 2.4 MHz ISM (Industrial, Scientific, Medical) band.

802.11b: A revision to the IEEE standard for direct sequence wireless LANs. Most 802.11b products have data rates of up to 11 Mbps, even though the standard does not specify the techniques for achieving these data rates.

802.11a: A revision to the IEEE standard that operates in the unlicensed 5 GHz band. Most 802.11a products have data rates up to 54 Mbps.
