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 an
existing wired LAN or it can form the basis for a new network. The basic element of a
wireless network is the radio cell. This is the area in which 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 USB Adapter 300 com-
plies with the 802.11n standard.
WPA
WPA was developed to improve the security provided by
WEP . WPA uses more complex
procedures to generate keys, such as TKIP (Temporal Key Integrity Protocol). In addition,
WPA can use an authentication server (e.g. a RADIUS server) to increase security.
WPA2-PSK/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 (
Roaming ). WPA2-PSK offers even higher security than WPA-PSK.
WPS
Wi-Fi Protected Setup
WPS considerably simplifies the setting up of wireless networks.
WPS automatically establishes secure wireless networks.
Access points automatically
create a network identification ( SSID ) and WPA2-PSK/WPA-PSK encryption. Clients can
be connected alternatively by entering a PIN or via special registration buttons on the
access point and on the client.
