802.11 - definition


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.
