Bandwidth requirements
SMARTBridgitconferencings oftware performsbest when you allocate at least 300 Kbps of network
bandwidthon your serverfor each meeting participant,both inbound to, andoutbound from, the
server.
EX A M P L E
If you have a 1.5 Mbps bandwidthconnection to your server,y ouc ansupport a maximum of five
concurrentparticipants with four openmicrophonesand four webcams at optimal performance(300
Kbps× 5 = 1,500 Kbps or1.5 Mbps).
Use the following tablet o estimate bandwidthrequirementsfor SMARTBridgit conferencing
software.

TT I P
Most shareddesktops maintain a bandwidthload of about 9 Kbps. However, the bandwidth
requiredfora s hareddesktop dependson the display’s resolution, the complexity of the content
beingsharedand the frequency at which the content changes. Forexample, a shared desktopw ith
aphotographicdeskt opbackgroundrequires morebandwidth than a shareddesktop with a plain,
solidc oloredbackground.
As an extremeexample, a shared desktopw ith a complex photographic backgroundand frequent
contentchanges can peak at 1,800 Kbps, while maintainingan averageof 300 Kbps.
