To work smoothly, Video Call requires a minimum broadband speed of 350Kbps upstream and downstream for a 2 endpoint call.
You also need an internet connection that sends and receives data quickly enough, so latency should not be more than 100 milliseconds.
Check your broadband speed by running a speedtest.
Video Call will work on ADSL, cable, optical fibre and 3G, 4G and 5G connectivity setups.
The set-up you are using may have an effect on the quality of your Video Call:
Make sure you have sufficient, sustained and available bandwidth of at least 350Kbps to hold a high-quality Video Call.
Video Call is built using peer-to-peer connections. This has the advantage that each connection finds the shortest possible path to send the data, and thus reduces the delay in the connection. But it also means that the more users enter a call, the more incoming and outgoing connections you will have.
Make sure to calculate an extra 350Kbps both upstream and downstream per extra party you bring into the call.
NOTE - Video Call is planning a future functionality where only the downstream bandwidth usage will increase, not the upstream when bringing in another party.
Healthdirect Video Call will use up to 1Mbps if that bandwidth is available to them. So, assuming you have enough available upstream and downstream bandwidth, and the call goes for 30 minutes, and it's a call with 2 endpoints, your data usage will be a maximum of:
If your call is made on minimum bandwidth usage, the usage may be more like:
It is likely that you will use something between these two numbers.
This calculation is made with 2 endpoints providing one audio-visual connection upstream and downstream each.
If you are planning to bring in a third, fourth or fifth party, your bandwidth usage will increase.
