When you start using an online video solution like Coviu, you may be concerned about how much bandwidth it might consume, whether your network connectivity is sufficient, and whether your monthly Internet bill will be impacted.

Network connectivity

Modern connectivity can take many forms - you might be connected via ADSL, Cable, optical fibre, 3G or 4G. Coviu is able to deal with any of these connectivity setups as long as you have a minimum of about 350Kbps each upstream and downstream for a 2 endpoint call.

However, the bandwidth is not the only important parameter. If you're connecting via a wireless LAN from a busy office, you might find that the packet loss and the delays introduced by the competing devices on the wireless make it impossible to get sustained bandwidth for Coviu.

Also pay attention to connecting from home on a lower bandwidth connection - if you are using your bandwidth for up- or downloads of other data, you might need to pause the other activities to get sufficient bandwidth for a Coviu call.

Make sure to have sufficient, sustained and available bandwidth of at least 350Kbps to hold a high quality video call over Coviu.

Bandwidth use per video

Coviu 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. However, 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 that we are planning future functionality where only the downstream bandwidth usage will increase, not the upstream when brining in another party.

Data usage per call

Next, you may be concerned about how your available monthly data quota may be impacted by a Coviu call.

Coviu videos 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:

Data Usage = 30 [min] * 60 [sec] * 1 Mbps * 2 [users] / 8 [bytes] =  450 MB.

If your call gets pushed down to the minimum bandwidth usage it's more like:

Data Usage = 30 [min] * 60 [sec] * 350Kbps * 2 [users] / 8 [bytes] =  158 MB.

Most likely it's something in between these two numbers.

The above numbers are calculated 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.
