2.4.2 DFS Frequency Status Table
This read-only table is applicable only for AU/BU supporting DFS when DFS is
enabled. Each entry in the table includes the following parameters:
Channel Avoidance
Period (min)
Applicable only for units that use a Country Code supporting DFS.
When DFS is enabled, this parameter defines the time that the
frequency will remain marked in the database as Radar Detected or
Adjacent to Radar after detecting radar activity. These frequencies
will not be used when searching for a new frequency. When this time
has elapsed, the unit frequency's marking will change to Radar Free.
The range is from 1 to 60 minutes.
SU Waiting Option (AU)
RB Waiting Option (BU)
Applicable only for AU/BU that uses a Country Code supporting DFS.
When DFS is enable, this parameter defines whether the
disassociation message sent by the AU/BU, after detecting radar
activity on the current frequency, will include a message instructing
the SU/RB to search only for the AU/BU before attempting to search
for another AU/BU. The message includes also the time period during
which the SU/RB should not search for any other AU/BU. The waiting
time is the Channel Check Time plus 5 seconds.
Defined Frequency
(MHz)
Applicable only for AU/BU. This parameter defines the
transmit/receive frequency when DFS is not enabled. If DFS is
enabled, it sets the initial operational frequency to be used upon
starting the DFS mechanism for the first time.
The range depends on the Country Code and selected Sub-Band.
Channel Check Time
(sec)
Applicable only for units that use a Country Code supporting DFS.
When DFS is enabled, this parameter defines the time allocated for
checking whether there is a radar activity on a new frequency after
power up or after attempting to move to a new frequency upon
detecting radar activity on the previously used frequency. During this
time the unit does not transmit.
The range is 1 to 3600 seconds.
Minimum Pulses To
Detect
Applicable only for units that use a Country Code supporting DFS.
When DFS is enabled, this parameter defines the minimum number
of radar pulses that should be detected before reaching a decision
that radar is active on the channel.
The range is from 1 to 100 pulses.
Current Bandwidth A read-only display of the current bandwidth used by the unit.
Frequency (MHz) The tested frequency
