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 net-
work, 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).
