Why the video sharing has bad quality under 5G but OK under Wi-Fi

[Frank83]

I use a laptop as host to make a video sharing under Webinar.(Network is fix network, and bandwidth is enough)

Then I use one mobile(A) as client to join this conference.  Then I do 2 test:

1. I use the 5G of mobile A to join, and when I watch the video, pool picture quality. I cannot see the subtitle very clearly.

2. I use mobile B as hotspot(mobile B network is 5G), the I use mobile A via mobile B (hotspot)to connect internet. and when I watch the video, the picture quality is ok.

3. I use the 5G of mobile B to join, and watch the video, the picture quality is bad.

So every time when I use mobile wifi connection(no matter is hotspot or the real home or office wi-fi)  to join th conference I got good quality video sharing. but once I change to 4G/5G, the quality will be bad.

I am not sure whether Zoom has some bandwidth limitation under 4G/5G senario?

Hi @Frank83, suggest looking into Bandwidth need when using 3G, 4G/LTE, or 5G for more info on this. A connection to WiFi will always be better (in most cases) compared to a mobile bandwidth. Let me know if that clears things up!
