GLOSSARY OF TERMS
AND ABBREVIATIONS
7 Chapter Counter Reset Paragraph
If you are new to wireless IP/Ethernet systems, some of the terms used
in this guide may be unfamiliar. The following glossary explains many
of these terms and will prove helpful in understanding the operation of
the iNET 900.
Access Point (AP)—The iNET unit in the network that provides syn-
chronization information to one or more associated Remote iNET units.
AP units may be configured for either the Access Point (master) or
Remote services. (See “Network Configuration Menu” on Page 28.)
Antenna System Gain—A figure, normally expressed in dB, repre-
senting 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
Association—Condition in which, the frequency hopping pattern of the
iNET 900 Remote is synchronized with the Access Point station in an
iNET network and is ready to pass traffic.
Authorization Key—Alphanumeric string (code) that is used to enable
additional capabilities to iNET 900 equipment.
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.
BPDU—Bridge Protocol Data Units
BPS—Bits-per-second (bps). 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.
CSMA/CA—Carrier Sense Multiple Access/Collision Avoidance
CSMA/CD—Carrier Sense Multiple Access/Collision Detection
Data Circuit-terminating Equipment—See DCE.
Data Communications Equipment—See DCE.
Data Terminal Equipment—See DTE.
