I was able to find this [Zoom Help Center Article](https://support.zoom.us/hc/en-us/articles/202920719-Meeting-Statistics), which states:

> You can [go] to [http://speedtest.net](http://speedtest.net/) to check your network bandwidth. Generally, we recommend 1.2 to 1.5Mbps upload/download for an optimal experience on desktop or room systems.

However, you mentioned a variety of connection sources such as: Internet, Home Internet, and 3G/4G, and I wasn’t able to locate any specifics for what your thresholds should be set as while monitoring to be considered.

I asked some of our Customer Success Managers if we had “Optimal Operating Target” values for these metrics, and they provided me with the following information:

```auto
| Metrics | Ideal Threshold | Notes |
|-------------|-----------------|------------------------------------------------------|
| Jitter | < 150ms | Variation in time between packets arriving |
| Latency | < 300ms | Delay between packets being sent/received |
| Packet Loss | < 20% | Number of packets failing to reach final destination |
| CPU Usage | < 90% | Send and Receive rate you experience during the call |

```

Are you developing an app and using the [List Meeting Participant’s QoS API](https://marketplace.zoom.us/docs/api-reference/zoom-api/dashboards/dashboardmeetingparticipantsqos) to obtain these numbers for your own monitoring?

I scratched the itch with a couple other questions and wanted to share what I learned, in case it helps…

> What happens when one or more attendees are on poor-quality connections, when this occurs, will they trigger a threshold monitoring alert?

Answer: Users receive a monitor alert, and they are encouraged to disable their camera.

Does this help get you moving in the right direction?
