WEP

IEEE 802.11
standard. It is used to protect wire-
less 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 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).
