The cable network was configured to provide 50 Mbps downstream and five Mbps upstream broadband service, overprovisioned by 25 percent. For all 10 participants, cameras and microphones were on. Conference applications were set to "gallery mode" with thumbnails of each person filling the screen, no slides were presented and the video conference sessions just included people talking.
The laptop under test used a wired connection to the cable modem to ensure that no variables outside the control of the service provider would impact broadband performance. Most notably, by using a wired connection, we removed the variable of Wi-Fi performance from our test setup.
During data collection, the conference app was the only app open on the laptop under test. Video conferencing sessions were set up and data consumption was measured over time.
We collected 10 minutes of data for each conferencing session under test to calculate the total consumption for one hour. The charts below show the data consumed for each of the 10 minutes of the conference session.
During the conference there was movement and discussion to keep the video and audio streams active throughout the period of data collection. For each test scenario, only one laptop was connected at a time to the broadband connection under test. Our goal was to measure the data consumption of one conferencing user on the broadband connection.
The other conference participants were on the internet; they were not in the lab. Once again, we used TShark a popular, widely used network protocol analyzer to capture and measure the data. For the laptop under test, we chose two that have quite different capabilities. The first was a low-cost laptop with an inch screen, like the ones students are often provided by school districts for at-home learning.
The second was a higher-cost laptop with a inch screen, like what we often see in an enterprise environment. Note the two laptops not only have quite different hardware components e. Once again, to avoid any appearance of endorsement, we are not identifying the specific laptops used. Table 1 shows hourly bandwidth consumption combining both upstream and downstream for the laptop under test, normalized to Gigabytes per hour. The table provides the data consumption for the low-cost and higher-cost laptops in each scenario with the four conferencing applications.
The following figures show the data consumption, in Megabytes, for each minute of the minute data collection for each of the permutations of our testing. Figure 2 shows data consumed each minute for each of the four apps when using the higher-cost laptop was in the person meetings. Figure 3 shows the data consumed each minute using App A and compares the two laptops used for data collection.
For each minute, the bar to the left is the lower-cost laptop and the bar to the right is the higher-cost laptop. Figure 4 shows the data consumed each minute using App B and compares the two laptops.
The bar to the left is the lower-cost laptop and the bar to the right is the higher-cost laptop. Figure 5 shows the data consumed each minute using App C and compares the two laptops.
Figure 6 shows the data consumed each minute using App D and compares the two laptops. Data Consumption Varies : The first takeaway is that different apps consume different amounts of bandwidth, as shown in Table 1, from 0. Comparing Laptops : In Table 1, the two columns of data show the differences between the lower-cost and higher-cost laptops for the data collections.
On the lower-cost laptop, Apps A, B and C consume about the same amount of data on an hourly basis. Comparing Laptops : The second column of data show that all apps on the higher-cost laptop consumed more bandwidth than the lower-cost laptop. This difference implies that when using the actual conferencing app not a web browser , processing power available in the laptop may be a determining factor in consumption.
Comparing Apps : App C was the most consistent in data consumption regardless of the laptop used. The other conference applications noticeably consumed more on the higher-cost laptop.
In summary, we observed a more than 7X variation in the data consumption of video conferencing with a very limited exploration of just two variables — laptop and video conferencing application.
Notably, however, when data consumption was at its highest, it was of the same magnitude as the data consumption of an HD video stream. This is an area ripe for further research and study, both to more comprehensively explore these variables e. Andy Dolan Senior Security Engineer.

This chart shows how much data a one-to-one meeting on Zoom uses per hour, depending on video quality:. As the number of people on a Zoom call increases, so does the data usage. Group Zoom meetings use up between MB and 2. This amounts to between Related: How to Join a Zoom Meeting. If you are concerned about the data consumption happening during your Zoom calls, here are some useful tips to help reduce data and bandwidth usage when using Zoom:. It is important to keep in mind that the amount of data you use on Zoom depends largely on the type of call and the number of people on a call.
Larger meetings usually use up more data, so make sure to plan accordingly.
