Towards the end of last year, I assisted with the coordination of a live awards event for World Teacher’s day.
For this event, we used the Zoom Webinars platform to connect remote communities with the main awards ceremony at Parliament House.

World Teacher's Day 2017 Awards – made possible via Zoom Broadcast
This event effectively came together last minute, and as a result – meant that we were not able to arrange a fixed line broadband connection at each end of the video broadcast. We were reliant on 3G mobile connections to receive and deliver video streams from remote communities.

The mobile-only connection in remote regions of the Northern Territory meant that we experienced packet loss up to 40% at times.

Typically with video conferencing, a high bandwidth, stable, fixed line connection is compulsory, and the video stream will not work at all without it.

That is of course unless the platform is Zoom.

Despite the at times high packet loss, Zoom was able to deliver the experience we needed, and helped bring the remote regions together – giving the regional award winners a platform on a state-wide scale.

Zoom vs WebEx – A packet Loss comparisonPacket Loss – a demo

In order to prove the resiliency and robustness of the Zoom platform in the face of packet loss, Zoom developed an in-house head-to-head test.

Packet loss is essentially data that never gets delivered to the intended destination – usually due to connection congestion.

Imagine a crisp clear photo, then imagine removing some of the photographic information from within the picture. Quickly it would become less vibrant and more faded as more and more information was removed.
The same basic principle exists within video compression technology.
The real technological feat is to deliver the best possible video quality given the dynamically changing Internet conditions of each user connecting to the meeting.

Simulating Packet Loss in a lab, Zoom demonstrates the quality of video delivered over a less than perfect connection outside of a vacuum (i.e. – real life), and to show how Zoom continues to deliver the quality to their users despite their connection woes.
Zoom did not alter or omit any of the test data to demonstrate favourable results.

Watch the below videos in full screen to get a better picture (pun intended) of the results of the test.

We think these results speak for themselves; however, superior video quality is just the beginning.
