High Quality Video Calling requires at least an upload/download speed of 400 kilobytes per second (kbps).
This means your upload/download speed should be about 3.2 Megabits per second (Mbps).
Do note however that (based on my experience) the upload speed is usually just one third (1/3) of the connection speed in Mbps.
