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 so-called 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 SE505 dsl/cable com-
plies with Standard 802.11g.
WPA
WPA was developed to improve security provided by WEP. To generate keys, WPA uses
more complex methods, e.g. TKIP (Temporal Key Integrity Protocol). In addition, WPA
can use an authentication server (e.g. a RADIUS server) to increase security.
WPA-PSK
WPA Preshared Key: Variant of
WPA
data encryption, in which new keys are automati-
cally generated at regular intervals by means of a keyword (Pre-shared key). The key is
updated after defined periods
(Rekey
Interval).
