Answer:

There are a number of ways to manage your data consumption in a live class.  However, it should be noted that the minimum amount of data usage for a one hour class will be approximately 240-250MB.  Take the following steps to reduce your data consumption:

  1. Do not broadcast your webcam.  Broadcasting your webcam doubles the amount of data you use, since you need to both send and receive audio and video streams (assuming there is at least one other webcam).
  2. If you are using the flash version, you can click the 'x' above each webcam feed to stop downloading the feed.  This will greatly reduce bandwidth consumption for meetings with webcams.
  3. Join the class using the HTML5 client.  At the time of this writing, webcams are not broadcast to the HTML5 client even if other participants are broadcasting, and the client environment is smaller, so this will go a long way in reducing data consumption.  Please see this guide on how to join a bigbluebutton session using html5 instead of Adobe Flash.
  4. Join the session in listen only mode.  Listen only mode allows you to receive the audio feed, but you will not be able to contribute except via the text chat.  This will allow you to ask a question through the text chat and listen to the audio response.  Please see this guide on how to join a live class using listen only mode.
