Appendix D – Glossary
Here is a selection of terms and definitions that may help reader to be more familiar with WLAN
technologies and understand the user manual better.
Ad Hoc Network
A short-term WLAN framework created between two or more WLAN adapters, without going
through an Access Point. An ad hoc network lets computers send data directly to and from one another.
For an ad hoc network to work, each computer on the network needs a WLAN card installed configured
for Ad Hoc mode.
Access point
A base station in a WLAN that acts as a central transmitter of data throughput and receiver of
WLAN radio signals.
Antenna
A device that sends and receives radio-frequency (RF) signals. Often camouflaged on existing buildings,
trees, water towers or other tall structures, the size and shape of antennas are generally determined by
the frequency of the signal they manage.
Authentication
A process that verifies the identity of a wireless device or end-user. A common form of authentication is
to verify identities by checking a user name and password to allow network access.
Backbone
A high-speed line or series of connections that form a major pathway within a network.
Bandwidth
The part of the frequency spectrum required to transmit desired information. Each radio channel has a
center frequency and additional frequencies above and below this carrier frequency that carry the
transmitted information. The range of frequencies from the lowest to the highest used is called the
bandwidth.
Bridge
A wireless device that connects multiple networks that are physically separate or use different media,
but which use similar standards.
Bridge Mode
An Access Pointy in bridge mode can operate as a WLAN bridge that connects two wired network
segments. The peer device also must be in bridge mode. This wireless bridge connection is equivalent to
a Wireless Distribution System (WDS).
