To define the parameters that are used in live RF views, select Configuration > System Settings > Advanced Settings > Live RF View Setting. These parameters are specific to each environment. Tuning the parameters enables you to see more accurate views.
You can specify the dBm values for which the system shows the intrusion detection and prevention regions in the sensor coverage views.
Detection range is the area over which sensors can reliably detect wireless activity. Intrusion Detection Display Threshold determines the threshold for this range.
Prevention range is the area over which sensors can prevent unauthorized wireless activity. Intrusion Prevention Display Threshold determines the threshold for this range.
Both the detection and prevention ranges are affected by parameters in the RF Propagation section.
The reliability of the prevention also depends on the Intrusion Prevention Level selected on the Configuration > WIPS > Intrusion Prevention page.
To configure live RF view setting:
- Select Configuration > System > Advanced Settings > Live RF View Setting.
- Specify the Intrusion Detection Display Threshold.
- Specify the Intrusion Prevention Display Threshold.
- Click Save.
