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.
