WDS Wireless domain services (WDS). An access point providing WDS on your wireless LAN maintains a
cache of credentials for CCKM-capable client devices on you r wir eles s L AN. 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.
WEP 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 pro vides 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.
