How much bandwidth do I need for live streaming?

The amount of bandwidth you’ll need depends on your encoding bitrate. For example, if you are encoding at 3,000 Kbps, you will need at least 3 Mbps of upload bandwidth. If your stream’s bitrate is too high relative to your upload bandwidth, your live stream will be unreliable for viewers. For example, a stream with a 6,000 Kbps bitrate doesn’t work on a network with a 5 Mbps upload bandwidth limit.

Above are the general required bandwidth for streaming guidelines. For example, the minimum bandwidth required for 1080p (HD) streaming is 5 Mbps, while the minimum 4K (UHD) streaming bandwidth is around 25 Mbps.
