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 router Gigaset 504 AGU com-
plies with Standard 802.11g.
WPA
WPA is a standard-compliant 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
