Operation of the CPB as Access Point

In this example, the left CPB works as an access point, the right
CPB as an access client. All clients in LAN 2 are connected to the
CPB-AP in LAN 1.

Operation of the CPB as Access Client (Firmware 2.0 and Higher)

The CPB can be operated as access client either in the infrastruc-
ture mode or in the ad-hoc mode. In ad-hoc operation, it has to be
ensured that all CPB-ACs are installed within the reach of the
wireless network. As a rule, ad-hoc operation is not recom-
mended, since transmission interferences may occur more easily.
In infrastructure mode, all clients have to be located within the
wireless network of the CPB-AP. Here, it is not necessary that they
are able to receive each other, since the access point controls the
complete communication.
