Typically, an

Access Point

is connected to a wired

LAN

. WDS lets access points 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 lets these systems 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.

WME

Wireless Multimedia Enhancements (WME) is a subset of the

802.11e

draft specification. It

uses four priority queues between an

Access Point

and its clients. WME provides an interim,

standards-based

QoS

solution.

WPA

Wi-Fi Protected Access (WPA) is a

Wi-Fi

Alliance version of the draft

IEEE 802.11i

standard.

It provides more sophisticated data encryption than

WEP

and also provides user

authentication. WPA includes

TKIP

and

802.1x

mechanisms.
