Collaborate Web Conferencing FAQs

How do I prepare my computer for a Collaborate Web Conferencing session?

Whenever a computer is going to be used for a Collaborate Web Conferencing session, there are two steps to follow.

Step 1.Checking System Requirements

Initially, you need to ensure you are running an operating system that is supported as well as a supported version of Java. Clicking on the following link will ensure you can proceed: Blackboard Collaborate webconferencing - First Time Users

In addition, please ensure the following:

• You are using the computer on which you will attend your session.
• Your computer is connected to the Internet and has a stable, reliable connection
• You have a microphone and speakers, preferably a headset to take full advantage of the collaborative capabilities during your session. Please check with the organization or instructor hosting the session if they will be using these features.
• You have the appropriate permissions to save files to your computer. If you are unsure, please contact your system administrator.

Step 2. Configuring your system

I am hearing echo in my session, how can I fix this?

Echo is caused primarily from sound being replayed back through a microphone and or can be related to latency with the connection.

These issues are typically solved with a couple different methods and via best practices for using our tools.

1) Important, when finished speaking, hit the talk button again to turn off your microphone.  This will prevent the #1 reason for echo, which is the sound of another person's voice re-playing back through the open microphone.

2) Latency related to the Internet connection of the user.  Recommend adjusting the connection speed lower, for example, for some users, a move from LAN to wireless makes a big difference.  That change can be made by the user from within the session. Click on --. Preferences --> scroll down and highlight "Connection"; adjust this lower, ie from LAN to Cable/DSL, or Wireless.  Experiment with what works.

3) Related to #2 above, be sure Internet connection is sufficient for the bandwidth requirements of the session.  If using wireless, ensure signal strength is excellent.  Weakness here causes issues.

4) Due to bandwidth intensive nature of the certain tools, be aware of bandwidth usage when using video and application sharing.

5) Ensure computer resources besides bandwidth are free for the tools the session requires.  Close any programs not required for use in the session to free up memory and processing power.

One note of hope for echo issues.  Blackboard Collaborate is working on echo cancellation for a future release of the software as they recognize the need to help our users mitigate this problem.
