GLOSSARY
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.
802.11
The IEEE standard that specifies carrier sense media access control and physical layer specifications
for 1- and 2-megabit-per-second (Mbps) wireless LANs.
802.11b
The IEEE standard that specifies carrier sense media access control and physical layer specifications
for 5.5- and 11-Mbps wireless LANs.
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.
Alphanumeric
A set of characters that contains both letters and numbers.
Associated
A station is configured properly to allow it to wirelessly communicate with an access point.
B
Bandwidth
Specifies the amount of the frequency spectrum that is usable for data transfer. It identifies the
maximum data rate that a signal can attain on the medium without encountering significant power loss.
BPSK
A modulation technique used by IEEE 802.11-compliant wireless LANs for transmission at 1 Mbps.
C
CCK
Complementary code keying. A modulation technique used by IEEE 802.11-compliant wireless LANs
for transmission at 5.5 and 11 Mbps.
Client
A radio device that uses the services of an access point to communicate wirelessly with other devices
on a local area network.
