  • 802.11a

An extension to 802.11 that applies to wireless LANs and provides up to 54-Mbps in the 5GHz band. 802.11a uses an orthogonal frequency division multiplexing encoding scheme rather than

  • 802.11b

Also referred to as 802.11 High Rate or Wi-Fi
An extension to 802.11 that applies to wireless LANS and provides 11 Mbps transmission (with a fallback to 5.5, 2 and 1-Mbps) in the 2.4 GHz band. 802.11b uses only DSSS. 802.11b was a 1999 ratification to the original 802.11 standard, allowing wireless functionality comparable to Ethernet.

  • 802.11e

A wireless draft standard that defines the Quality oService (QoS) support for LANs, and is an enhancement to the 802.11a and 802.11b wireless LAN (WLAN) specifications. 802.11e adds QoS features and multimedia support to the existing IEEE 802.11b and IEEE 802.11a wireless standards, while maintaining full backward compatibility with these standards.

  • 802.11g

Applies to wireless LANs and is used for transmission over short distances at up to 54-Mbps in the 2.4 GHz bands.

  • 802.1X

Not to be confused with 802.11x (which is the term used to describe the family of 802.11 standards) 802.1X is an IEEE standard for port-based Network Access Control that allows network administrators to restricted the use of IEEE 802 LAN service access points to secure communication between authenticated and authorized devices.
