1. Select the "Enable iPCF" option for the required WLAN interface.
You configure the security settings in "Security > WLAN > Basic".
iPCF-MC
Requirements to be able to use iPCF-MC:
● Client SCALANCE W722-1 RJ-45 (MLFB 6GK5722-1FC00-0AA0 / 6GK5722-1FC00-
0AB0 (US version))
● The management interface and data interface must be operated in the same frequency
band and mode and must match in terms of their wireless coverage. iPCF-MC will not
work if both wireless interfaces are equipped with directional antennas that cover different
areas.
● The management interfaces of all access points to which a client can change must use
the same channel. A client scans only this one channel to find accessible access points.
● Transmission based on IEEE801.11h (DFS) cannot be used for the management
interface. 801.11h (DFS) is possible for the data interface.
● The client cannot be operated with "Use Allowed Channel only".
● "Force roaming on Ethernet down" is automatically mirrored on the second interface.
When should iPCF-MC be used?
iPCF was developed to achieve short handover times when roaming between cells. The
iPCF-MC technique allows short handover times even for freely mobile clients and when a
lot of cells are involved or a large number of channels is being used.
iPCF and iPCF-MC are not compatible with each other and cannot be used at the same
time on a device.
With 11n devices, remember that the assignment of the WLAN interfaces is fixed for
iPCF-MC.
– WLAN1: Data interface
WLAN2: Management interface
