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.

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 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. A WLAN can be operated in Ad-hoc mode or Infrastructure mode.

WLAN is currently specified in Standard IEEE 802.11. The Gigaset SE551 WLAN dsl/cable 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).

XR

eXtended Range

XR technology increases a WLAN's range and ensures better coverage of the area in the home or office network. When activated at the Access Point, this function can considerably increase the range to the network adapters, although at the expense of the data transfer rate.
