Cisco TelePresence SX20 Quick Set  Administrator Guide
Cisco Proximity allows users to see, control, capture and share 
content directly on their own mobile devices (smartphone, tablet, 
or laptop), when the device is near a video system.
The mobile device can automatically pair with the video system 
when it comes within range of ultrasound transmitted by the video 
system.
The number of simultaneous Proximity connections depends 
on the type of video system. The client warns new users if the 
maximum number of connections has been reached.
