We all know Zoom performs well when you’re backed by a fast and stable Internet. But what about the real world, where most likely you don’t get that luxury?

The testing procedure consists of 2 series of tests for Zoom video calls:

1. Without Speedify;
2. Speedify on with Streaming Mode enabled.

In terms of devices and operating systems, we tested it on an Android smartphone and a macOS laptop. We combined Wi-Fi and cellular on the smartphone / Wi-Fi and the USB tethered phone connection on the Mac.

The evaluation is done both subjectively and objectively as follows:

• We screen capture and analyze the Zoom stream video quality;
• We walk towards the edge of the Wi-Fi network. This helps us simulate:
  • insufficient bandwidth conditions, as we get away from the Wi-Fi router;
  • unreliable connectivity at the edge of Wi-Fi with dead spots and packet loss;
  • disconnecting Wi-Fi internet and how quick it switches to cellular.

For the Speedify tests, we looked at the bandwidth, latency and packet loss. And, of course, how they are affected by our “course” away from Wi-Fi.

First off – we have the test with no Speedify running. As you can imagine, once we get near the edge of Wi-Fi, the image starts stuttering. And finally buffering takes over. At some point, after 15+ seconds of freezing image, it does switch to cellular.

Video was very similar on both tested platforms – macOS and Android.

Next, we have testing on a Macbook. The video itself didn’t even stutter for one bit. Here’s how the bandwidth distribution looks like:

First of all, Speedify makes it possible to use both Wi-Fi and cellular at the same time. That’s why you see both connections being used together at times on the graph above. When Wi-Fi starts failing, you notice that with the help of Speedify cellular takes over. The general bandwidth is constant at around 1 Mbps. And that steady streaming rate is good for Zoom video calls and any streaming platform actually.

The little red x-es above symbolize the moments when packet loss over the Wi-Fi connection was very high – over 5%. If Speedify would not have been running, then you would have ended up like in the first case – buffering and maybe even being dropped from the call.

The Android test with Speedify Streaming Mode was similar to the Mac one – video was perfect in the sense that quality was good and it didn’t break.

There you have it – one of the best Zoom meeting tricks for you is to use Speedify. Speedify’s Streaming Mode makes a huge difference to Zoom calls.

To put it in context, here’s what happens under the hood of Streaming Mode. Speedify monitors statistics in real-time about how each of your Internet connections is performing. As connections change, and other apps start or stop sending data, Speedify adjusts its strategies on the fly. So, now you’re not chained to a chair near your Wi-Fi router, hoping to get a good signal, while on Zoom calls. You can walk around, and even leave the house without dropping the call. You don’t need to worry about it. Just make your Zoom call: if there’s any way to get it through, Speedify will make it happen.
