For bandwidth, we recommend 1Mbits download and 0.5 Mbits upload speed. Users can test their actual bandwidth using speedtest.net.
For hardware, we recommend a dual-core CPU with at least 2G of memory. We recommend any operating system capable of running the latest versions of Google Chrome and Mozilla FireFox.
For browser, We recommend running either FireFox or Chrome. Why? Both browsers provide excellent support for web real-time communications (WebRTC). Safari, IE, and Edge will work as well, but FireFox and Chrome will deliver better audio in lower bandwidth conditions.
In short, if the user is having any problems (such as audio is garbled or they are periodically getting disconnected), we recommend trying either FireFox or Chrome. If the problems persist, it’s likely an issue with their network. BigBlueButton will give them notifications to help troubleshoot.
If the presenter needs to share their desktop, then we recommend running FireFox.
