Evaluating the impact of Screen Share on your network data usage
When you connect your device or computer to the board using Screen Share, the screen sharing
protocol compresses the image from your device or computer. The protocol may transmit only
areas of the screen that change. This can make it difficult to estimate the impact of Screen Share
on a network where many users would like to screen share simultaneously.
For example, in a school where 30 teachers are using Screen Share simultaneously, 10% of
teachers might be streaming video while 90% might be sharing static content with periodic
updates. The network could expect to see an additional 5 MB/sec in network traffic. Use the table
below to help estimate the impact of Wireless Screen share on your network.
Content being shared Data rate transmission
Static content, minor screen movement 20 kb/sec
Static content, periodic scrolling or refresh Spikes briefly to 500–600 kb/sec, returns to 20
kb/sec
