Collaborate Ultra Help & Support

Delivering sessions on Collaborate to students in China

Recommendations to improve real-time (synchronous) sessions

When delivering Collaborate sessions to China-based students, please follow this guidance:


  • Use a hardwired Ethernet connection when presenting.
    • Broadcast quality is partially dependant on the presenter’s network connection, although certain students may also experience a low broadcast quality if they have poor internet connectivity themselves.
    • Recording quality is based on the presenter’s connection, other than when a student or guest speaker talks or screen shares, at which point the quality is based on their connection.


  • The use of video (webcams) should be limited to only the necessary people who need to be seen.
    • In the settings, camera functionality can be disabled for students.
    • The more video streams that are enabled simultaneously the greater the pull on the bandwidth of all users.
    • If students need to share their video and audio, we advise them to turn this on to speak, and turn it off again once finished.


  • Use the Collaborate file sharing and whiteboard features for content instead of screen sharing, which can be very bandwidth heavy especially when combined with having your webcam on.
  • For demonstrations, you could use screenshots or record a micro-lecture on Panopto.


  • Record the session so those who may have had a poor connection in the live session, or drop off due to other technical problems, can catch up afterwards.

Class Size:

  • Smaller class sizes usually work better for those students with poor connections.

Additional Information

  • There are no restrictions accessing Blackboard Collaborate in China.  
  • Inconsistent or slow internet connection speeds in China (high latency, lack of bandwidth, jitter and packet loss) can also impact on the performance of Collaborate. 
  • Students using WiFi can contribute to any latency/bandwidth issues. 
  • Slow internet connections can prevent users in China from being able to access real-time sessions or share audio, video or uploaded materials. Additionally, it can lead to frequently dropping and reconnecting, to not being able to connect at all.
