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 SX763 WLAN dsl complies with Standard 802.11g.

WPA

WPA is a new standard-conformant solution for greater security in wireless networks. WPA is meant to replace the existing WEP standard (Wired Equivalent Privacy) and offers more reliable encryption and authentication methods.

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 extends the range in a WLAN and in so doing allows improved coverage of the desired range in home or small office networks. Activating this function at the access point can extend the range to the network adapters considerably, though the data transfer rate is reduced as a result.
