Wireless Switch™
(WX™)
A switch in a 3Com Mobility System. A WX provides forwarding,
queuing, tunneling, and some security services for the information it
receives from its directly attached Managed Access Points (MAPs). In
addition, the WX coordinates, provides power to, and manages the
configuration of each attached MAP, by means of the MAP Control
Protocol.
WISP Wireless Internet service provider. A company that provides public
wireless LAN (WLAN) services.
WLAN Wireless LAN. A LAN to which mobile users (clients) can connect and
communicate by means of high-frequency radio waves rather than
wires. WLANs are defined in the IEEE 802.11 standard.
WPA Wi-Fi Protected Access. The Wi-Fi Alliance’s version of the Temporal Key
Integrity Protocol (TKIP) that also includes a message integrity code
(MIC) known as
Michael . Although WPA provides greater wireless
security than the Wired-Equivalent Privacy protocol (WEP), WPA is not
as secure as IEEE 802.11i, which includes both the RC4 encryption used
in WEP and Advanced Encryption Standard (AES) encryption, but is not
yet ratified by IEEE. See also
AES ; RC4 ; TKIP .
WPA IE A set of extra fields in a wireless frame that contain Wi-Fi Protected
Access (WPA) information for the access point or client. For example, a
Managed Access Point (MAP) uses the WPA IE in a beacon frame to
advertise the cipher suites and authentication methods that the MAP
supports for its encrypted SSID.

X.500 A standard of the International Organization for Standardization (ISO)
and International Telecommunications Union Telecommunication
