FAST RAOMING
The Fast roaming function allows a specific log-in to an existing Access Point without
initiating a scanning process.
Roaming list:
The roaming list contains all Access Points to which a connection is to be established. The
list will be processed in the given order. The first entry is used for the first connection
attempt.
Modbus/TCP roaming control:
Enables the clients Modbus/TCP API. A PLC can then retrieve the current position in the
roaming list or can initiate fast roaming to any entry in the roaming list.
Add new entry to Roaming List:
Allows entering an Access Point in the roaming list. The MAC address of this Access Point is
required to enter. Furthermore, the channel (1-13) on which the Access Point can be
reached may be entered. If the channel is unknown, you may select the Auto option.
The Fast roaming page also supports Access Points (Aps) of other manufacturers. This will
be continued, and is even required for processing dynamic channels, in particular in the 5
GHz band and including DFS. The APs channel may statically be preset on 2.4 GHz or with
5 GHz with the DFS option disabled. The client will then only process these APs in the
given order and with the given roaming thresholds. If the device cannot jump to a certain
AP, the device will go in default scan mode, and the remaining roaming parameters, like
e.g. the "Disabled channels", will be enabled.
