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 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 influence by various factors, such as RSS, SNR, throughput estimate, and
average MCS (downlink).
Complete the following steps
to create a test call.
From the navigation bar, click
Video Call
QoE.
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.
In Test Name, enter the
name for the test you wish to perform.
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. 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.
