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 com-

plies 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-PSK
WPA Pre-shared Key
Variant of

WPA

data encryption in which new keys are automatically generated at regu-

lar 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.
