WEP Wired Equivalent Privacy: A security protocol for wireless local area networks

(WLANs) defined in the 802.11b standard. WEP is designed to provide the same level of

security as that of a wired LAN. LANs are inherently more secure than WLANs because

LANs are somewhat protected by the physicalities of their structure, having some or all part of

the network inside a building that can be protected from unauthorized access. WLANs, which

are over radio waves, do not have the same physical structure and therefore are more vulnerable

to tampering. WEP aims to provide security by encrypting data over radio waves so that it is

protected as it is transmitted from one end point to another. However, it has been found that

WEP is not as secure as once believed. WEP is used at the two lowest layers of the OSI model

- the data link and physical layers; it therefore does not offer end-to-end security.

Wi-Fi Wireless Fidelity: Wi-Fi is a label for devices conforming to the IEEE 802.11b standard

for WLAN. The IEEE 802.11b standard has been published by the IEEE, which does not

perform conformance testing. In order to establish such a conformance testing process, the

Wi-Fi Alliance (formerly known as WECA) has been formed, which tests devices for

conformance with the IEEE 802.11b standard and issues the Wi-Fi label for conforming devices.

WME Wireless Multimedia Extensions: Also known as Wi-Fi Multimedia (WMM), it is a

Wi-Fi Alliance interpretability certification, based on the IEEE 802.11e draft standard. It

provides basic Quality of service (QoS) features to IEEE 802.11 networks. WMM prioritizes

traffic according to 4 AC (Access Categories) - voice, video, best effort and background.

However, it does not provide guaranteed throughput. It is suitable for simple applications that

require QoS, such as Wi-Fi Voice over IP (VoIP) phone.

WPA Wi-Fi Protected Access: WPA was created by the Wi-Fi Alliance in 2002, in part out of

impatience with the slow-moving IEEE 802.11i standard. The industry consortium’s

consensus was that an alternative to WEP was needed quickly, and WPA was the result. To

avoid multiple standards and conflicts later on, WPA was designed from the get-go to be

compatible with IEEE 802.11i and was based on its early draft specifications.
