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.
