This requirement, although not indicated in the certification document, is needed following the tests
performed in the certification lab.
4.2.6.2.4.3 DFS Parameters
The DFS Parameters submenu is available only if DFS is supported by the
current Sub-Band. The DFS Parameters submenu includes the following
parameters:
4.2.6.2.4.3.1 DFS Option
The DFS Option enables or disables the radar detection and dynamic frequency
selection mechanism.
The default is Enable.
4.2.6.2.4.3.2 Frequency Subset Definition
The Frequency Subset Definition parameter defines the frequencies that will be
used in the DFS mechanism. The available frequencies according to the Sub-
Band are displayed, and each of the frequencies in the list is associated with an
index. The frequencies subset can be defined by entering the indexes of the
required frequencies, or “A” to select all available frequencies.
The default is the complete list of frequencies available in the Sub-Band.
4.2.6.2.4.3.3 Channel Check Time
The Channel Check Time 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 AU does not transmit.
The range is 1 to 3600 seconds.
The default is 60 seconds.
4.2.6.2.4.3.4 Channel Avoidance Period
The Channel Avoidance Period 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 1 to 60 minutes.
The default is 30 minutes.
4.2.6.2.4.3.5 SU Waiting Option
The SU Waiting Option defines whether the disassociation message sent by the
AU, after detecting radar activity on the current frequency, will include a message
