Wi-Fi logger

This task lets you log Wi-Fi network parameters using a Test Agent equipped with a Wi-Fi card. For details on supported hardware, see here.

You can change the Wi-Fi interface and its settings dynamically while running a test using the Wi-Fi switcher task.

For normal configuration, use the Wi-Fi interface configuration settings.

Parameters

See the common parameters page for the following:

  • Parameters that are set on the test step level: Duration, Fail threshold, and Wait for ready.

  • SLA thresholds for monitors: SLA Good and SLA Acceptable.

  • Advanced settings common to all test tasks: Delayed start.

General

  • Clients: Test Agent Wi-Fi interfaces to log.

Thresholds for errored seconds (ES)

For each of the following thresholds, Paragon Active Assurance will indicate an errored second if the quantity drops below the threshold during that second.

  • Signal (dBm): Received Signal Strength Indication (RSSI).

    Min: −120 dBm. Max: −25 dBm. Default: −100 dBm.

  • TX bitrate (Mbit/s): Theoretical maximum transmit data rate (from Test Agent to access point) in current conditions as reported by the Wi-Fi card.

    No default.

  • RX bitrate (Mbit/s): Theoretical maximum receive data rate (from access point to Test Agent) in current conditions as reported by the Wi-Fi card.

    No default.

  • TX retries: Percentage of transmit retries.

    No default.

Result metrics

  • Received Signal Strength Indication (dBm): Received Signal Strength Indication.

  • TX bitrate (Mbit/s): Theoretical maximum transmit data rate (from Test Agent to access point) reported by the Wi-Fi card.

  • RX bitrate (Mbit/s): Theoretical maximum receive data rate (from access point to Test Agent) reported by the Wi-Fi card.

  • Tx MCS index: Transmit Modulation Coding Scheme index (used from Test Agent to access point).

  • Rx MCS index: Receive Modulation Coding Scheme index (used from access point to Test Agent).

  • Guard interval (ms): Guard interval used.

  • Number of transmit MIMO streams: Number of Multiple-Input Multiple-Output (MIMO) transmit streams.

  • Number of receive MIMO streams: Number of Multiple-Input Multiple-Output (MIMO) receive streams.

  • TX retries: Percentage of transmit retries.

  • ES (%): Aggregated errored second percentage, taking into account all types of error.

  • ES Signal (%): Errored second percentage for Signal (RSSI).

  • ES TX bitrate (%): Errored second percentage for transmit data rate.

  • ES RX bitrate (%): Errored second percentage for receive data rate.

  • ES TX retries (%): Errored second percentage for transmit retries.

If the network changes while the Wi-Fi logger is running (for example, if you switch to a new access point), that change is recorded in the message log which also appears in the output.
