WMM
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:

.
WPA
Wi-Fi Protected Access (WPA) is a Wi-Fi Alliance version of the draft IEEE 802.11h
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
802.11h , 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 802.11h that
uses AES but another encryption mode (
OCB
) for encryption and integrity.
