802.11 is a set of IEEE standards for wireless local area networks (WLAN). The most common variant is 802.11g, which is backwards compatible with the older B variant. 802.11g devices are sometimes marked as 802.11b/g to indicate this compatibility. There is a newer version – 802.11n – that provides higher maximum speeds and better range. The 802.11g standard’s typical speeds are rated up to 54 Mbps.
