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.
