802.1X
Also called 802.1X for 802.11. 802.1X is the new 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.
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.
Ad Hoc Network
A set of characters that contains both letters and numbers.
Alphanumeric
A station is configured properly to allow it to wirelessly communicate with an access point.
Associated
B
Specifies the amount of the frequency spectrum that is usable for data transfer. It identifies the
Bandwidth
maximum data rate that a signal can attain on the medium without encountering significant power loss.
Binary phase shift keying. A modulation technique used by IEEE 802.11-compliant wireless LANs for
BPSK
transmission at 1 Mbps.
A security feature for use with dynamic WEP keys. If your client adapter uses LEAP or EAP-TLS
Broadcast key
rotation authentication and you enable this feature, the access point changes the dynamic broadcast WEP key
that it provides at the interval you select.
