WDS

WEP

Wireless domain services (WDS). An access point providing WDS on your wireless LAN maintains a cache of credentials for CCKM-capable client devices on your wireless LAN. When a CCKM-capable client roams from one access point to another, the WDS access point forwards the client's credentials to the new access point with the multicast key. Only two packets pass between the client and the new access point, greatly shortening the reassociation time.

Wired equivalent privacy. An optional security mechanism defined within the 802.11 standard designed to protect your data as it is transmitted through your wireless network by encrypting it through the use of encryption keys.

WMM	Wi-Fi Multimedia. WMM is a component of the IEEE 802.11e wireless LAN standard for quality of
	service (QoS). It specifically supports priority tagging and queuing.
workstation	A computing device with an installed client adapter.
WPA	Wi-Fi Protected Access. A standards-based security solution from the Wi-Fi Alliance that provides data
	protection and access control for wireless LAN systems. It is compatible with the IEEE 802.11i
	standard but was implemented prior to the standard’s ratification. WPA uses TKIP and MIC for data
	protection and 802.1X for authenticated key management.
WPA2	Wi-Fi Protected Access 2. The next generation of Wi-Fi security. It is the Wi-Fi Alliance’s
	implementation of the ratified IEEE 802.11i standard. WPA2 uses AES-CCMP for data protection and
	802.1X for authenticated key management.
