Note:
In client mode, the DFS function is disabled by default. Caused by the radar detection
during data transmission, strong interferences might occur in particular at the client,
which have to be evaluated as Potential Radar Pulses. A very high CPU load and faulty,
frequently occurring radar detection cycles are results of that. For this reason, DFS should
be enabled in client mode only if the client output power exceeds 23dB, and if 30dBm are
required for establishing a stable data connection. If another 5GHz device is located near
the device in question, this might also cause significant disturbances to the client mode, if
DFS is activated there as well.
Warning:
A wrong country setting may lead to illegal radio frequency settings which are punishable
by law.
The operator is solely responsible for ensuring the correct country setting.
C
HANNEL :
Depending on operator settings, the device can choose a transmission channel
automatically or use a manually selected channel. We recommend using automatic channel
selection (option Auto). In the event of channel interferences, the device can only switch
to an interference-free channel if automatic channel selection is activated.
Note:
5GHz channels cannot be selected statically; instead, they are chosen randomly from the
available free channels. (This constraint is required for device approval by law.)
In case other WLANs are operated in parallel, manual radio field planning is essential in
order to avoid limitations to wireless communications. In this case, the transmission
channel should be chosen manually.
Please note that DFS needs to be switched off in order for channels to be selected
manually.
