16-QAM
Quadrate amplitude modulation. A modulation technique used by IEEE 802.11-compliant wireless
LANs for transmission at 24 and 36 Mbps.
64-QAM
Quadrate amplitude modulation. A modulation technique used by IEEE 802.11-compliant wireless
LANs for transmission at 48 and 54 Mbps.
802.1X
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
802.11
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
802.11a
implementation of the physical layer for wireless UNII bands (see UNII,
provides four channels per 100 MHz of bandwidth.
The IEEE standard that specifies carrier sense media access control and physical layer specifications
802.11b
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
802.11g
for 54-Mbps 2.4-GHz wireless LANs.
The IEEE standard that defines security standards for wireless LANs. It specifies encryption,
802.11i
authentication, and key management strategies for wireless data and system security. It includes the
TKIP and AES-CCMP data-confidentiality protocols.
A
A wireless LAN data transceiver that uses radio waves to connect a wired network with wireless
access point
stations.
A wireless network composed of stations without access points.

Advanced Encryption Standard encryption algorithm using Counter Mode with Cipher Block Chaining
AES-CCMP
Message Authentication Code Protocol (CCMP). AES-CCMP is the encryption protocol in the 802.11i
standard.
A set of characters that contains both letters and numbers.
alphanumeric
A station is configured properly to enable it to wirelessly communicate with an access point.
