Glossary of Wireless Networking Terms
Access Point:
An internetworking device that seamlessly connects wired
and wireless networks.
Ad-Hoc:
A group of computers, each with LAN adapters, connected as an
independent wireless LAN.

Notebook Network Card
Backbone:
The core infrastructure of a network. The portion of the
network that transports information from one central location to
another, where it is unloaded onto a local system.
Base Station: In mobile telecommunications, a base station is the central
radio transmitter/receiver that maintains communications with the mobile
radio/telephone sets within its range. In cellular and personal communications
applications, each cell or micro-cell has its own base station; each base
station in turn is interconnected with other cells or bases.
BSS:
BSS stands for Basic Service Set. It is comprised of an access point
and all the LAN PCs that are associated with it.
ESS:
ESS (ESS-ID, SSID) stands for Extended Service Set. More than one
BSS is configured to become an Extended Service Set. LAN mobile users
can roam between different BSSes in an ESS (ESS-ID, SSID).
Ethernet:
A popular local area data communications network, which
accepts transmission from computers and terminals. Ethernet operates
on a 10 or 100Mbps base band transmission rate, using an unshielded,
twisted-pair cable.
Infrastructure:
An integrated wireless and wired LAN is called an
Infrastructure configuration.

RTS Threshold:
aware of each other. The RTS/CTS mechanism can solve this "hidden
node problem". If the packet size is smaller than the preset RTS
Threshold size, the RTS/CTS mechanism will NOT be enabled.
WEP:
keys and the popular RC4 encryption algorithm. Wireless devices without
a valid WEP key will be excluded from network traffic.
