BreezeMAX Extreme 172 System Manual
Frequencies Status Table of each sector uses also the status information of
relevant frequencies in the frequencies table of the other sector. In these
configurations the DFS mechanism will avoid selection of the channel used by the
other sector.
The parameters that affect the DFS mechanism are defined by the relevant
standards and cannot be configured.
The DFS Menu includes the following options:
 Show
 Update General Parameters (available only if Country Code is Universal)
 Show Frequencies Status Table
4.7.2.2.2.1.1 Show
The displayed information depend on the Country Code being used.
4.7.2.2.2.1.1.1 If Country Code is other than Universal:
Select this option to display the following:
 DFS Support
 DFS Type: According to the DFS type defined in the Country Code (see
“DFS/DCS” on page 102).
 Channel Availability Check Time (sec): The minimum time to check a
frequency for the presence of radar activity.
 Channel Non Occupancy Period (min): If radar was detected on a certain
frequency, this frequency will be considered as Unavailable for a period
defined by the Channel Non Occupancy Period parameter. During this period
this frequency will not be used by the DFS mechanism.
 Startup Test Valid Period (hours): After deciding that a frequency is Available
(no radar was detected by the Channel Availability Check algorithm), it is
considered as an Available frequency for a period defined by the Startup Test
Valid Period parameter. During this period the unit may start transmitting on
this frequency without performing a Channel Availability Check.
 Radar Detection Threshold (dBm): The Radar Detection Threshold is the
minimum level of received radar signal that must be detected by the algorithm
