Introduction
Short for wireless fidelity and is meant to be used generically when referring to any type of 802.11 network, whether 802.11b, 802.11a, 802.11g, dual-band, etc .
Wi-fi is a wireless technology that uses radio frequency to transmit data through the air.
IEEE (Institute of Electrical and Electronics Engineers) established the 802.11 Group in 1990. Specifications for standard ratified in 1997.
Initial speeds were 1 and 2 Mbps.
IEEE modified the standard in 1999 to include 802.11 a and b.
802.11g was added in 2003.
802.11b equipment first available, then a, followed by g.
IEEE create standard but Wireless Ethernet Compatibility Alliance certifies products.
