W
WAN
A Wide Area Network (WAN) is a communications network that spans a relatively large geographical area,
extending over distances greater than one kilometer. A WAN is often connected through public networks,
such as the telephone system. It can also be connected through leased lines or satellites.
The Internet is essentially a very large WAN.
WDS
A Wireless Distribution System (WDS) allows the creation of a completely wireless infrastructure. Typically,
an
. WDS allows access points to be connected wirelessly. The
access points can function as wireless repeaters or bridges.
WEP
Wired Equivalent Privacy (WEP) is a data encryption protocol for
wireless networks. All wireless
stations and access points on the network are configured with a static 64-bit (40-bit secret key + 24-bit
initialization vector (IV)) or 128-bit (104-bit secret key + 24-bit IV)
for data encryption. It uses a
stream cipher to encrypt the frame body and CRC of each
frame before transmission.
Wi-Fi
A test and certification of interoperability for
products based on the
standard promoted
by the
, a non-profit trade organization.
WINS
The Windows Internet Naming Service (WINS) is a server process for resolving Windows-based computer
names to IP addresses. It provides information that allows these systems to browse remote networks using
the Network Neighborhood.
Wireless Networking Framework
There are two ways of organizing a wireless network:
•
Stations communicate directly with one another in an
network, also known as an inde-
pendent basic service set (
).
•
Stations communicate through an
network. A single access
point creates an infrastructure basic service set (
) whereas multiple access points are organized in
an extended service set (
).
WLAN
Wireless Local Area Network (WLAN) is a
that uses high-frequency radio waves rather than wires to
communicate between its nodes.
