Testing Video Call Quality

The Video Call QoE page allows network administrators to test the quality of video calls made through applications, such as Zoom, over the Wi-Fi network.

Because video calls have high bandwidth requirements, they are susceptible to issues such as latency and jitters which can be analyzed and resolved with the help of video call testing. The test results are captured in a report, which provides insight into various network parameters, pointing to potential corrective action that can enhance video quality.
The Video Call QoE page displays information about the test calls created, such as the status of the calls, the number of participants, the creation time and end time of the call, the quality of experience (QoE), and a link to the report. If the QoE of a call is good, a green dot is displayed in the QoE column. If the QoE is poor, a red dot is displayed.

Video Call QoE Workflow

You can run a video call QoE test by following the steps listed in Creating a Test Call

After the test call is completed, a test call report is generated after approximately 8 to 10 minutes. For more information, refer to Video Call Test Report. You can click the Test Call Report icon to view the report.

In the report, select the client MAC address of the participants to view the video call QoE. If the call quality is good, the Video Call QoE displays in a green capsule. If the call quality is poor, it appears in a red capsule. Wi-Fi connection quality directly impacts the video call QoE. If the Wi-Fi connection quality of both participants is good, the video call QoE is good, and vice versa. Wi-Fi connection quality is influenced by various factors, such as RSS, SNR, throughput estimate, and average MCS (downlink).

Selecting the client MAC address displays the Client Troubleshooting page and clicking the AP MAC address displays the AP Details Report.

Creating a Test Call

Complete the following steps to create a test call.

  1. From the navigation bar, click Video Call QoE.
  2. Click Create Test Call.
    Note: Only network administrators can create test calls and these calls can be attended only by clients within the RUCKUS Wi-Fi network.
  3. In Test Name, enter the name for the test you wish to perform.
  4. Click Create.
    A Test Call Info page is displayed containing information about the test name, a link to make the Zoom call, and prerequisites. Clicking the link takes you to the Zoom Meeting web user interface. You must use the Zoom desktop or mobile application (not the web browser version) for the test call. As with any Zoom meeting, you can edit the audio and video settings, chat with participants (only two in this case), record the meeting, use the reactions icons, share the screen, and so on.

    Only two participants are allowed on the call and they must join the call immediately. For best analysis, both participants must be on the call for at least five minutes, enabling audio and video features on the call.

    The MAC address of the participants must be added manually every time a report is generated. Reports are not generated if both participants are connected through a wired network or if no participants join the meeting.
