Windows Internet Naming Service. In Windows environment, the service that manages the correspondence
between client station names and LAN locations relative to their IP addresses.
WLAN
Wireless Local Area Network. A LAN that provides networking using radio frequencies rather than wires for
communication.
WLAN association
An association refers to the connection between the WLAN client and the AP. There are two types of
associations: passive scanning and active scanning. In passive scanning, APs send out information such
as SSIDs and supported rates, while the client passively scans the radio channels for beacons and probe
responses. The client then selects an AP. The client keeps scanning even after the association is made (to
support roaming). In active scanning, clients send out probe requests. If the probe request contains an
SSID, only the APs with the correct SSID will respond. If the probe request contains a broadcast, all the
APs will respond.
WLAN client
Any PC, PDA, or phone set that supports the 802.11a and 802.11b/g protocols can be a WLAN client.
WLAN handset
A wireless terminal that is connected to the system through a wired Access Point (AP). The radio
connection between the wireless terminal and the AP is specified by the 802.11 family of specifications.
The WLAN handset range includes Alcatel-Lucent IP Touch 310/610 WLAN Handsets and Alcatel-Lucent
OmniTouch 8118/8128 WLAN Handsets. WLAN handsets are sometimes referred to as MIPT (Mobile IP
Touch) handsets.
