Terms and Abbreviations

If you are new to wireless IP or Ethernet systems, some of the terms used in this guide may
be unfamiliar. The following glossary explains many of these terms and is helpful in
understanding the operation of the transceiver system.

Access Point (AP)—The transceiver in the network that provides synchronization information
to one or more associated Remote radios.

Antenna System Gain—A figure, normally expressed in dB, representing the power increase
resulting from the use of a gain-type antenna. System losses (from the feedline and coaxial
connectors, for example) are subtracted from this figure to calculate the total antenna system
gain.

AP—See Access Point.

Associated—Condition in which the frequency hopping pattern of the Remote is
synchronized with the AP station in a network, is recognized by the AP, and is ready to pass
traffic.

Authorization Key—Alphanumeric string (code) that is used to enable additional capabilities
in a transceiver.

Bit—The smallest unit of digital data, often represented by a one or a zero. Eight bits (plus
start, stop, and parity bits) usually comprise a byte.

Bits per second—See bps.

bps—Bits per second. A measure of the information transfer rate of digital data across a
communication channel.

Byte—A string of digital data usually made up of eight data bits and start, stop, and parity
bits.

Data Communications Equipment—See DCE.

dBi—Decibels referenced to an “ideal” isotropic radiator in free space. Frequently used to
express antenna gain.

dBm—Decibels referenced to one milliwatt. An absolute unit used to measure signal power,
as in transmitter power output, or received signal strength.
