802.11
Family of IEEE standards for wireless LANs first introduced in 1997. The first standard to be implemented, 802. 11b, specifies from 1 to 11 Mbps in the unlicensed band using DSSS (direct sequence spread spectrum) technology. The Wireless Ethernet Compatibility Association (WECA) brands it as Wireless Fidelity (WiFi).

A common shared media LAN technology. A LAN technology that is in wide use today utilizing CSMA/CD (Carrier Sense Multiple Access/Collision Detection) to control access to the physical medium (usually a category 5 Ethernet cable). Normal throughput speeds for Ethernet are 10 Mbps, 100 Mbps, and 1 Gbps.

Highspeed, lowerror data network covering a relatively small geographic area (up to a few thousand meters). LANs connect workstations, peripherals, terminals, and other devices in a single building or other geographically limited area. LAN standards specify cabling and signaling at the physical and datalink layers of the OSI model. Ethernet, FDDI, and Token Ring are widely used LAN technologies. Compare with MAN and WAN.
