Video calls, school and telehealth at home
What calls actually need
| Call type | Upload | Download |
|---|---|---|
| Zoom one-to-one, 720p HD | 1.2 Mbps | 1.2 Mbps |
| Zoom group, 720p HD | 2.6 Mbps | 1.8 Mbps |
| Zoom 1080p | 3.8 Mbps | 3.0 Mbps |
| Microsoft Teams meeting, recommended | 2.5 Mbps | 4.0 Mbps |
| Telehealth video visit, minimum (NC health dept.) | 1.5 Mbps | 1.5 Mbps |
Upload matters for calls
Downloads bring video to you. Uploads send your face and voice out. Calls are one of the few things at home that need decent upload.
Tips for clear calls
- Sit near the router or use a cable.
- Pause big downloads and cloud backups during the call.
- Close other video tabs.
- If the picture freezes, turn your camera off for a moment, audio uses very little.
- Most telehealth services also offer a phone visit if video drops.
Homework
School platforms, research and documents use very little speed. The main need is a steady connection at the times kids study.
Key takeaways
- A one-to-one HD call needs about 1.2 Mbps each way.
- Upload speed matters for calls more than most things.
- On satellite you may notice a short pause before replies. Let people finish, then speak.
