In some applications, however, it may be desirable to divide the clients the 
radio cell into different groups, each of which is treated in a certain way by 
the access point. It may be necessary, for example, to operate a public wire-
less network without any encryption simultaneous to a protected, 802.11i-, 
WPA- or WEP-encrypted wireless network that excludes unauthorized par-
ties.
The Multi-SSID function of the BAT access points is ideally suited to scenar-
ios like this. This function enables a physical WLAN interface of an access 
point to be assigned with more than one SSID. Up to eight different logical 
radio cells—each with its own SSID—can be supported by a single WLAN in-
terface.
