1.3 Wireless Connectivity
Introduction The SpeedTouch™570 features a Wireless LAN Access Point which behaves as a hub
and allows wireless connectivity between several devices and the local (W)LAN and -
via the SpeedTouch™570 DSL router - to the public network, e.g. the Internet.
WLAN technology enables these devices to communicate with each other in a locally
mobile fashion, without the need for a wired environment.
Wireless basics The WLAN's 'radio' link is a shared medium. As no physical connection exists between
the SpeedTouch™570 and wireless clients, a name must be given to allow unique identi-
fication of your WLAN radio link. This is done by the Service Set ID (SSID). Wireless
clients must be part of this SSID environment in order to be able to communicate with
other clients on the (W)LAN - including the SpeedTouch™570 .
The IEEE802.11b standard for WLANs allows several WLAN networks using different
radio channels to be co-located. Several channels are available for use which are associ-
ated to a slightly different frequency in the allowed range. The SpeedTouch™570
supports operation on all allowed channels and is able to select the best radio channel
at each start-up.
Wireless security Since the SpeedTouch™570 (W)LAN environment is a radio environment, precautions
must be taken to ensure that your wireless network is safe from malicious intruders. In
addition to providing the possibility of giving a personalized SSID name to the wireless
network, the SpeedTouch™570 features a physical registration mechanism, an Access
Control List (ACL) and enhanced Wired Equivalent Privacy (WEP) 64- or 128-bits
encryption to secure your network and to control wireless client access.
Wireless client
requirements
Only WLAN client adapters compliant to IEEE802.11b DSSS, will be able to communi-
cate with the SpeedTouch™570 , and with the other members of the SpeedTouch™570
(W)LAN environment.
It is advisable that the WLAN client adapter is Wireless Ethernet Compatibility Alliance
(WECA) Wi-Fi™ (*) certified to ensure smooth interoperability.
To use SpeedTouch™570 's encryption security features, the WLAN client adapters
should at least support 64-bit WEP encryption.
