Quadrate amplitude modulation. A modulation technique used by IEEE 802.11-compliant wireless LANs for transmission at 24 and 36 Mbps.

Quadrate amplitude modulation. A modulation technique used by IEEE 802.11-compliant wireless LANs for transmission at 48 and 54 Mbps.

Also called 802.1X for 802.11. 802.1X is the standard for wireless LAN security, as defined by the Institute of Electrical and Electronics Engineers (IEEE). An access point that supports 802.1X and its protocol, Extensible Authentication Protocol (EAP), acts as the interface between a wireless client and an authentication server, such as a Remote Authentication Dial-In User Service (RADIUS) server, to which the access point communicates over the wired network.

The IEEE standard that specifies carrier sense media access control and physical layer specifications for 1- and 2-megabit-per-second (Mbps) 2.4-GHz wireless LANs.

The IEEE standard that governs the deployment of 5-GHz OFDM systems. It specifies the implementation of the physical layer for wireless UNII bands (see UNII, UNII 1, and UNII 2) and provides four channels per 100 MHz of bandwidth.

The IEEE standard that specifies carrier sense media access control and physical layer specifications for 5.5- and 11-Mbps 2.4-GHz wireless LANs.

The IEEE standard that specifies carrier sense media access control and physical layer specifications for 54-Mbps 2.4-GHz wireless LANs.

The IEEE standard that defines security standards for wireless LANs. It specifies encryption, authentication, and key management strategies for wireless data and system security. It includes the TKIP and AES-CCMP data-confidentiality protocols.

A

access point		A wireless LAN data transceiver that uses radio waves to connect a wired network with wireless
		stations.
ad hoc network		A wireless network composed of stations without access points.
AES-CCMP		Advanced Encryption Standard encryption algorithm using Counter Mode with Cipher Block Chaining
		Message Authentication Code Protocol (CCMP). AES-CCMP is the encryption protocol in the 802.11i
		standard.
alphanumeric		A set of characters that contains both letters and numbers.
associated		A station is configured properly to enable it to wirelessly communicate with an access point.
