What is a Wireless LAN?
31
U Base station in client mode
For binding single devices with Ethernet interfaces to a Wireless LAN, BAT
Wireless base stations can be put into the so-called client mode, in which
they behave like a conventional Wireless LAN adapter and not like a base
station. Due to the client mode, it is also possible to integrate devices like
PCs or printers having only one Ethernet interface into a Wireless LAN.
Note: An Access Point in normal mode further clients can log on, but not in
client mode.
U Multiple radio cells with Multi-SSID
Conventionally, a wireless network card supports exactly one radio cell.
These radio cells are given a network name, known as the ‘SSID’ (Service
Set Identifier), that is entered into the access points and network cards during
configuration. Certain settings that apply to the radio cell can be defined un-
der the SSID during the configuration of the access point. The settings in-
clude, for example, the data transfer speed and the first WEP key, which is
also used as passphrase for encryption with 802.11i and WPA. Those clients
that are programmed with the SSID can make use of the radio cell and work
with the parameters as defined. The access point treats all clients on an
equal basis
