TPC
If the country of operation of the S1100 device requires conformity to the TPC (Transmit
Power Control) regulations, the transmission power of its radio is automatically reduced by
3 dB before leaving the Verint factory. However, in case of a weak wireless link (that is, a
link with an RF margin of less than 15 dB), you have the opportunity to use the maximum
transmission power (see page 36).
DFS
To follow the DFS (Dynamic Frequency Selection) regulations specified by ETSI for the
selected country, it is the master 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.
A master device in DFS mode goes through the following sequence when booting up:
1. The device goes through the standard startup procedure.
Starting order delay (0-15 minutes)
Normal operation
Radar detection (60 seconds)
Unit initialization (3 seconds)
Frequency scan (10-20 seconds)
