Bandwidth requirements
SMART Bridgit conferencing software performs best when you allocate at least 300 Kbps of network
bandwidth on your server for each meeting participant, both inbound to, and outbound from, the
server.
E X A M P L E
If you have a 1.5 Mbps bandwidth connection to your server, you can support a maximum of five
concurrent participants with four open microphones and four webcams at optimal performance (300
Kbps × 5 = 1,500 Kbps or 1.5 Mbps).
Use the following table to estimate bandwidth requirements for SMART Bridgit conferencing
software.
SMART Bridgit conferencing software resource Bandwidth required
One shared desktop with a 1024 × 768 resolution 9 Kbps
One open microphone using the standard quality setting 25 Kbps
One open microphone using the low quality setting 15 Kbps
One open webcam with moderate activity 60 Kbps

Most shared desktops maintain a bandwidth load of about 9 Kbps. However, the bandwidth
required for a shared desktop depends on the display’s resolution, the complexity of the content
being shared and the frequency at which the content changes. For example, a shared desktop with
a photographic desktop background requires more bandwidth than a shared desktop with a plain,
solid colored background.
As an extreme example, a shared desktop with a complex photographic background and frequent
content changes can peak at 1,800 Kbps, while maintaining an average of 300 Kbps.
