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.
