DFS
To follow the DFS (Dynamic Frequency Selection) regulations specified by ETSI for the
selected country, it is the master S3100 device that performs the tasks relative to
frequency channel selection and radar detection. In other words, you cannot choose the
frequency channel on which the edge device will run.
The automatic selection of the frequency channel limits the number and the configuration of
the wireless cells. Furthermore, when colocating many cells, all masters must “see” each
other.
Note: DFS is required only in the 5 GHz band.
You should start the master first, then power the client when the other device is in normal
operation.
The boot sequence of client (transmitter) devices is:
1. The device goes through the standard startup procedure.
2. The device roams through the channels in the available frequency bands to locate its
master.
3. When the master is located, the client device runs normally on the selected frequency
channel.
Colocated Cells
You can operate many wireless cells in the same location, provided you follow guidelines
relative to frequency channel, wireless passkey, and distance.
Regarding frequency channel, you cannot manually select one in the 5.40–5.725 GHz band
in Europe; for the detailed procedure, see page 16.
The wireless passkeys of colocated cells must be different from one another, regardless of
their frequency channels.
