W

WAG

WLAN Access Gateway. Performs a function similar to a firewall that limits the IP connectivity of WLAN users. Filter rules are pushed to it from the 3GPP network.

W-APN

WLAN Access Point Name (W-APN). Used to identify a specific IP network and a point of interconnection to that network (Packet Data Gateway).

W-CDMA

Wideband Code Division Multiple Access.

W-CDR

Wireless LAN type of CDR.

Wi-Fi

Wireless local area network that uses the IEEE 802.11a, b, or g radio protocols.

WiMAX

Worldwide Interoperability for Microwave Access.

WISP

Wireless Internet Service Provider.

WLAN

Wireless Local Area Network.

3GPP WLAN IP Access

Access to an IP network via PLMN via tunnel. See also WLAN Direct IP Access.

WLAN Access Gateway

See WAG.

WLAN Access Network

See WLAN AN.

WLAN AN

WLAN Access Network. A function that represents the wireless provider's AAA infrastructure from the point of view of the 3GPP network.

WLAN coverage

The area where a WLAN UE can connect to a WLAN.

WLAN Direct IP Access

Access to an IP network directly from a WLAN AN without passing data to a PLMN via tunnel. See also 3GPP WLAN IP Access.

WLAN UE

WLAN User Equipment.

WLAN UE's local IP address

The address used to deliver a packet to a WLAN UE in a WLAN AN. It identifies the WLAN UE in the WLAN AN. The WLAN UE's local IP address may be translated by a Network Address Translation prior to being received by any other IP network, including a PLMN.

WLAN UE's remote IP address

The address used by the data packet encapsulated inside the WLAN UE to the PDG tunnel. It represents the address of the WLAN UE in the network which the WLAN UE is accessing via the PDG.
