TCP/IP

Protocol family on which the Internet is based. IP forms the basis for every computer-to- computer connection. TCP provides applications with a reliable transmission link in the form of a continuous data stream. TCP/IP is the basis on which services such as WWW, Mail and News are built. There are other protocols as well.

URLUniversal Resource LocatorGlobally unique address of a Domain on the Internet.WANWide Area Network

A WAN is a network that is not restricted to one particular area, such as the Internet. A WAN is run by one or more public providers to enable private access. You access the Internet via an Internet Provider.

WEPWired Equivalent Privacy

WEP is a security protocol defined in the IEEE 802.11 standard. It is used to protect wireless transmissions in a WLAN against unauthorised access through Encryption of the data transmitted.

Wireless network

See WLANWLANWireless 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 a wired LAN or it can form the basis for a new network. The basic element of a wireless network is the cell. This is the area where the wireless communication takes place.

WLAN is currently specified in Standard IEEE 802.11. The Gigaset WLAN Repeater 108 complies with Standard 802.11g.

WPA

WPA was developed to improve the security provided by WEP. WPA uses complex procedures to generate keys, such as TKIP (Temporal Key Integrity Protocol). In addition, WPA can use an authentication server (e.g. a RADIUS server) to increase security.

WPA-PSKWPA Pre-shared Key

Variant of WPA data encryption, in which new keys are automatically generated at regular intervals by means of a keyword (Pre-shared Key). The key is updated after defined periods (Rekey Interval).
