Virtual server
A virtual Server provides a service on the Internet that runs on another network compo-
nent, not on the server itself. The Gigaset SE361 WLAN can be configured as a virtual
server. It will then direct incoming calls for a service via Port Forwarding directly to the
appropriate Port of the network component in the local network.
WAN
Wide Area Network
A WAN is a wide area network, which is not restricted to one particular area. The Internet
is the most frequently used WAN. A WAN is run by one or more public providers to ena-
ble private access. You access the Internet via an Internet Provider.
WEP
Wired Equivalent Privacy
WEP is a security protocol defined in the IEEE 802.11 standard. It is used to protect wire-
less transmissions in a WLAN against unauthorised access with Encryption of the data
transmitted.
WLAN
Wireless LAN
Wireless LANs enable network components to communicate with a network using radio
waves as the transport medium. A wireless LAN can be connected as an extension to an
existing wired LAN or it can form the basis for a new network. The basic element of a
wireless network is the radio cell. This is the area in which wireless communication takes
place. A WLAN can be operated in Ad-hoc mode or Infrastructure mode.
WLAN is currently specified in the IEEE 802.11 standard. The Gigaset SE361 WLAN com-
plies with standard 802.11g.
WPA
WPA was developed to improve the security provided by WEP. WPA uses more complex
procedures to generate keys, e.g. TKIP (Temporal Key Integrity Protocol). In addition,
WPA can use an authentication server (e.g. a RADIUS server) to improve security.
WPA-PSK
WPA Pre-shared Key
Variant of WPA data encryption in which new keys are generated automatically at reg-
ular intervals by means of a keyword (Pre-shared Key). The key is updated at defined
intervals (Rekey interval).
