Evaluating the impact of Screen Share on your network data usage

When you connect your device or computer to the display 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 occasional
updates. In such an instance, you could expect to see an additional 5 Mbps in network traffic. Use
the following table to help estimate the impact of wireless Screen Share on your network.
Content being shared
Static content with minor screen movement
Static content with periodic scrolling or
refreshes
Gaming or streaming video with major screen
