4.2.6.2.4.3.7Clear Radar Detected Channels After Reset

When the Clear Radar Detected Channels After Reset is enabled, after the next reset all viable frequencies will be marked in the database as Radar Free, including frequencies previously marked as either Radar Detected or Adjacent to Radar. In addition, the AU will start operation using its default frequency.

The default is Disable.

4.2.6.2.4.4 Channel Reuse Parameters (DFS+)

The Channel Reuse algorithm enables returning to the original channel under certain conditions that indicate low radar activity on the original channel. The conditions are that radar was detected in this channel not more than N times (Maximum Number of Detections in Assessment Period) during the last T hours (Radar Activity Assessment Period). When the Channel Reuse Option is enabled, then by the end of the Channel Avoidance Period the unit will attempt returning to the original frequency, provided these conditions are met.

The Channel Reuse Parameters submenu includes the following options:

„Channel Reuse Option: Enabling/disabling the Channel Reuse algorithm. The default is Disable.

„Radar Activity Assessment Period: The period in hours used for assessment of radar activity in the original channel.

The range is 1 to 12 hours. The default is 5 hours.

„Maximum Number of Detections in Assessment Period: The maximum number of radar detections in the original channel during the Radar Activity Assessment Period that is required for reaching a decision to try again the original channel.

The range is 1 to 10 radar detections.

The default is 5 radar detections.

4.2.6.2.4.4.1Show DFS Settings And Data

Upon selecting the Show DFS Settings and Data, the values of all DFS parameters and the current operating frequency will be displayed. The current defined frequency subset as well as the defined subset (to be used after the next reset) are also displayed. In addition, all the applicable frequencies will be displayed together with their status in the database (Radar Free, Radar Detected or Adjacent to Radar).
