Security in wireless networksEncryption

Any network, be it wired or wireless, is exposed to the risk of eavesdropping.

Connecting your local network to the public network exposes your data and applications

to not inconsiderable risks. As with an individual connection, you should always protect

your network PCs against external attacks, e. g. via emails, with a virus scanner.

These virus scanners however do not provide any protection against unauthorised

access from outside (hackers). To counter this risk, Gigaset data products offer various

encryption procedures that largely rule out unauthorised access (hacking) to your wire-

less network.

WEP encryption (Wired Equivalent Privacy) encodes data for sending using a key that

you have defined. Once they reach the recipient, who uses the same key, the data are

restored to the state before you sent them. Recipients who do not know this key cannot

read the content of this data stream or only after a great deal of effort.

There are two security levels for calculating the encryption key:

64-bit mode

128-bit mode

Wireless Protected Access (WPA) is a new standard-compliant solution for greater secu-

rity in wireless networks. WPA is meant to replace the existing WEP standard (Wired

Equivalent Privacy) and offers more reliable encryption and authentication methods.

With your Gigaset PC Card 54 you can use WPA encryption regardless of the operating

system used. WPA encryption is particularly recommended where the highest security

is required.

The range is up to 300 m in the open. In buildings, the maximum range is up to 30 m.

The operating environment, the nature of the rooms and building may reduce the range

considerably. You can boost the range of your wireless network by placing a repeater,

e. g. a Gigaset WLAN Repeater, at the limit of its range.
