My problem:

Viewers receive error "stream interrupted" during Facebook Live broadcasts.  During a 20 minute broadcast, only 5- 10-second "live clips" can be seen separated by minutes of frozen images and frequently dropping audio.

Attempted fixes:

Tried broadcasting from LTE from my iPhone instead of via my home WIFI (not ideal).  Results improved but there seems to be a severe broadcast lag...greater than 30 seconds.

Tried broadcasting again from WIFI with inconsistent results.

My Question:

What are the bandwidth requirement for broadcasting to Facebook Live either over WIFI or over Cellular broadband (LTE)?

My specs:  

Phantom 4
Software Versions

I'm not too sure what the minimal requrements for live streaming are, but I use a Verizon MiFi with good success. Of course, signal quality will affect how good your streaming quality is.
This is a video I streamed from Twin Falls, ID, and I had great LTE signal there.
