WMM
Wireless Multimedia (WMM) is a IEEE technology standard designed to improve the quality of audio, video
and multimedia applications on a wireless network. Both access points and wireless clients (laptops,
consumer electronics products) can be WMM-enabled. WMM features are based on is a subset of the
WLAN IEEE 802.11e draft specification. Wireless products that are built to the standard and pass a set of
quality tests can carry the "Wi-Fi certified for WMM" label to ensure interoperability with other such
products. For more information, see the WMM page on the Wi-Fi Alliance Web site: http://www.wi-fi.org/

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.
WPA2
Wi-Fi Protected Access (WPA2) is an enhanced security standard, described in IEEE 802.11i, that uses
Advanced Encryption Standard (AES) for data encryption.
The original WPA uses Temporal Key Integrity Protocol (TKIP) for data encryption. WPA2 is backwards-
compatible with products that support the original WPA.
WPA2, like the original WPA, supports an Enterprise and Personal version. The Enterprise version
requires use of IEEE 802.1x security features and Extensible Authentication Protocol (EAP) authentication
with a RADIUS server.
The Personal version does not require IEEE 802.1x or EAP. It uses a Pre-Shared Key (PSK) password to
generate the keys needed for authentication.
WRAP
Wireless Robust Authentication Protocol (WRAP) is an encryption method for 802.11i that uses AES but
another encryption mode (OCB) for encryption and integrity.
X
XML
The Extensible Markup Language (XML) is a specification developed by the W3C. XML is a simple, flexible
text format derived from Standard Generalized Markup Language (SGML), which is defined in ISO
8879:1986, designed especially for electronic publishing.
