4.5.3.5.8 DFS
The DFS option is applicable only for units operating in the 5 GHz frequency
bands using a Band Name specifying that DFS should be used. The DFS feature is
managed separately for each sector (see “DFS” on page 128). The BTS level DFS
parameters are common to both sectors (if applicable) and it includes the
following parameters:
 DFS Type
 Frequencies Management Level
4.5.3.5.8.1 DFS Type
The DFS Type parameter defines the DFS algorithm to be used. This read-only
parameter is set according to the DFS type specified in the selected Band Name.
The available DFS algorithm (according to the selected Band Name) are:
 ETSI/FCC: The algorithm searches (passive listening) for radar signals
according to relevant ETSI or FCC regulations. To increase the probability of
radar detection for compliance with the relevant regulations, additional silence
zone is added to the uplink at the expense of slightly reduced throughput in
the downlink. This means that although the specified DL-UL Ratio is 60-40,
