A base station in a WLAN that act as a central transmitter and receiver of WLAN radio signals.
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.
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.
