Setting RSSI Threshold and Dwell Time for a Site

The RSSI Received Signal Strength Indicator. RSSI is a mechanism by which RF energy is measured by the circuitry on a wireless NIC (0-255). The RSSI is not standard across vendors. Each vendor determines its own RSSI scale/values. and dwell time configuration allows the administrators to perform the following actions:

  • Classify the type of client.
  • Analyze presence patterns.
  • Determine if the usage has increased over time.

To modify the default RSSI thresholds and dwell time configuration parameters for a site, complete the following steps:

  1. In the WebUI, set the filter to Site.

    The dashboard context for the selected site is displayed.

  2. Under Manage, click Guests > Presence Analytics.
  3. Click the Config icon.
  4. In the Data Collection table, click the Edit Threshold icon.

    The Thresholds window is displayed.

  5. Under Visitors, specify the value for the RSSI threshold field.
    By default, the RSSI threshold value is set to -65 dBm Decibel-Milliwatts. dBm is a logarithmic measurement (integer) that is typically used in place of mW to represent receive-power level. AMP normalizes all signals to dBm, so that it is easy to evaluate performance between various vendors.. You can specify a value within the range of -100 to 0.
  6. Under Passersby, specify the value for the RSSI threshold field.
    By default, the RSSI threshold value is set to -90 dBm. You can specify a value within the range of -100 to 0.
  7. Under Conversion, specify the values for Dwell Time.
    By default, the dwell time is set to 5 minutes.
  8. Click Save.
