WDS
A Wireless Distribution System (WDS) allows the creation of a completely wireless
infrastructure. Typically, an Access Point is connected to a wired LAN . 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 802.11 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)
Shared Key for data encryption. It uses a RC4 stream cipher to encrypt the frame
body and CRC of each 802.11 frame before transmission.
Wi-Fi
A test and certification of interoperability for WLAN products based on the IEEE 802.11
standard promoted by the
Wi-Fi Alliance
, 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 Ad hoc Mode network, also
known as an independent basic service set ( IBSS ).
• Stations communicate through an Access Point in an Infrastructure Mode network. A
single access point creates an infrastructure basic service set ( BSS ) whereas multiple
access points are organized in an extended service set ( ESS ).
WLAN
Wireless Local Area Network (WLAN) is a LAN that uses high-frequency radio waves
rather than wires to communicate between its nodes.
