What uses upload bandwidth?
Video meetings, cloud backups, sending attachments, publishing videos, livestreaming and remote desktop tools all send data. A connection may have fast downloads but limited upload capacity.
Signs of limited upload speed
Calls may become blocky, cloud backups may take a long time and other users may experience high latency when a device saturates the upload link.
Improving upload performance
Pause large backups during important calls, use Ethernet where possible, enable sensible router quality-of-service settings and compare packages that advertise stronger upstream capacity.
