Glossary

B

beacon

BOOTP

BPSK

broadcast packet

A wireless LAN packet that signals the availability and presence of the wireless device. Beacon packets are sent by access points and base stations; however, client radio cards send beacons when operating in computer to computer (Ad Hoc) mode.

Boot Protocol. A protocol used for the static assignment of IP addresses to devices on the network.

Binary phase shift keying is a modulation technique used by IEEE 802.11b-compliant wireless LANs for transmission at 1 Mbps.

A single data message (packet) sent to all addresses on the same subnet.

C

CCK

CCKM

Complementary Code Keying. A modulation technique used by IEEE 802.11b-compliant wireless LANs for transmission at 5.5 and 11 Mbps.

Cisco Centralized Key Management. Using CCKM, authenticated client devices can roam from one access point to another without any perceptible delay during reassociation. An access point on your network provides wireless domain services (WDS) and creates a cache of security credentials for CCKM-enabled client devices on the subnet. The WDS access point's cache of credentials dramatically reduces the time required for reassociation when a CCKM-enabled client device roams to a new access point.

cell

The area of radio range or coverage in which the wireless devices can

 

communicate with the base station. The size of the cell depends upon the speed

 

of the transmission, the type of antenna used, and the physical environment, as

 

well as other factors.

client

CSMA

A radio device that uses the services of an Access Point to communicate wirelessly with other devices on a local area network.

Carrier sense multiple access. A wireless LAN media access method specified by the IEEE 802.11 specification.

D

data rates

dBi

The range of data transmission rates supported by a device. Data rates are measured in megabits per second (Mbps).

A ratio of decibels to an isotropic antenna that is commonly used to measure antenna gain. The greater the dBi value, the higher the gain, and the more acute the angle of coverage.
