How much bandwidth is used during a session?

The amount of bandwidth that GoToMeeting uses during a session varies depending on the features that are being used. For example, screen sharing will use more bandwidth during a PowerPoint presentation with multiple slides than it will when a single image is being shown. Also see How do I speed up my internet connection?

In general, it's recommended that you have at least 1 Mbps of bandwidth available if you plan to use all 3 of the features listed below during a session. Less bandwidth will still work, but the session performance may suffer because of it. More bandwidth will provide a superior experience. You can estimate the amount of bandwidth a session will require using these data-usage averages:
  • Computer audio (VoIP): 0.04 Mbps (40 Kbps)
  • Webcam sharing (HDFaces): 0.7 Mbps (700 Kbps) to 2Mbps, depending on number and size of webcams in use
  • Screen sharing: 0.04 Mbps (40 Kbps) to 8 Mbps, depending on the size and rate of changes happening on screen
Both webcam and screen sharing will automatically reduce their usage (by reducing the frame rate, etc.) if the available bandwidth requires it.
Note: This is based on the ISP unit measurement standard for Data Transfer Rates (Bits). This is not to be confused with the unit measurement standard for Data File Size (Bytes). 8 Bits = 1 Byte.
