WAN – Wide Area Network
A network of computers that covers a large
geographical distance. With respect to the
Ericsson W25, WAN refers to the Internet.

WCDMA – Wideband CDMA
The radio access technology for wideband
wireless access supporting 3G services. It
allows very high speed multimedia services
like wireless Internet access and
videoconferencing. WCDMA is also known as
CDMA DS (Direct Sequence).

WEP – Wired Equivalent Privacy
A method for data encryption on wireless
networks. Data is encrypted into blocks of
either 64 bits length or 128 bits length. The
encrypted data can only be sent and received
by users with access to a private encryption
key.

Wireless
A common term used to describe
telecommunications in which radio waves
(rather than some form of wire) carry the
signal over part or all of the communication
path.

WLAN – Wireless Local Area Network
A WLAN is a network in which a mobile user
can connect to a LAN through a wireless
(radio) connection. The IEEE 802.11 standard
specifies the technologies for Wireless LANs.

WPA – Wi-Fi Protected Access
An authentication and encryption standard for
wireless networks. WPA addresses the
security limitations of WEP, providing a
stronger data encryption method; TKIP. WPA
data encryption is based on a WPA master
key. The master key is derived from the
passphrase and the network name (SSID) of
the device.

WPA2 – Wi-Fi Protected Access 2.
An enhanced version of WPA. For data
encryption, WPA2 uses AES instead of TKIP.

WUI – Web User Interface
In Ericsson W3x the WUI refers to a built-in
web based configuration tool with wizard
support.
