CHAP Challenge Handshake Authentication Protocol. An authentication
protocol that defines a three-way handshake to authenticate a user
(client). CHAP uses the MD5 hash algorithm to generate a response to
a challenge that can be checked by the authenticator. For wireless
connections, CHAP is not secure and must be protected by the
cryptography in such authentication methods as the Protected
Extensible Authentication Protocol (PEAP) and Tunneled Transport Layer
Security (TTLS).
client The requesting program or device in a client-server relationship. In a
wireless LAN (WLAN), the client (or supplicant) requests access to the
services provided by the authenticator. See also supplicant.
co-channel See CCI.
interference
collision domain A single half-duplex IEEE 802.3 Carrier Sense Multiple Access with
Collision Detection (CSMA-CD) network. A collision occurs when two
or more Layer 2 devices in the network transmit at the same time.
Ethernet segments separated by a Layer 2 switch are within different
collision domains.

plenum cable
coverage area In 3Com Wireless Switch Manager (3WXM), the smallest unit of floor
space within which to plan access point coverage for a wireless LAN
(WLAN). The number of access points required for a coverage area
depends on the type of IEEE 802.11 transmission used, and the area's
physical features and user density.
CPC Communications plenum cable. See plenum-rated cable.
CRC Cyclic redundancy check. A primitive message integrity check.
