In the case of access points with two wireless modules, one module implements communication of the access points with each other. The radio link for the stations, e.g. a mobile crane system, is established by the second wireless module. Wireless coverage of larger areas can therefore be provided with the same device.

In the case of SCALANCE W786, this only concerns access points which can, however, be configured as client modules through Web-based management. Then, depending on the selected variant, a maximum of one radio module will be available as a client.
