Glossary

BPSK	A modulation technique used by IEEE 802.11b-compliant wireless LANs for
	transmission at 1 Mbps.
broadcast packet	A single data message (packet) sent to all addresses on the same subnet.

C

CCK

cell

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

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	A radio device that uses the services of an Access Point to communicate
	wirelessly with other devices on a local area network.
CSMA	Carrier sense multiple access. A wireless LAN media access method specified
	by the IEEE 802.11 specification.

DSSS

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.

Dynamic host configuration protocol. A protocol available with many operating systems that automatically issues IP addresses within a specified range to devices on the network. The device retains the assigned address for a specific administrator-defined period.

A type of low-gain (2.2-dBi) antenna consisting of two (often internal) elements.

The text name that refers to a grouping of networks or network resources based on organization-type or geography; for example: name.com—commercial; name.edu—educational; name.gov—government; ISPname.net—network provider (such as an ISP); name.ar—Argentina; name.au—Australia; and so on.

Domain Name System server. A server that translates text names into IP addresses. The server maintains a database of host alphanumeric names and their corresponding IP addresses.

Direct sequence spread spectrum. A type of spread spectrum radio transmission that spreads its signal continuously over a wide frequency band.
