Multicast probably isn’t even necessary to justify this, judging by what 
appears to be the default resolution of the test video. Let’s be generous with 
our assumptions and assume these laptops are 1920x1080 native resolution. Given 
this assumption, we can infer that the test video’s resolution about ½ of this, 
based on the attached screenshot of the video. So we have a 960x540 resolution 
video to playback. What of bitrate? Let’s be generous again and give it 
1800kbps for video, 192kbps for audio, totaling to a hair under 2mbps per 
stream (real-world for this resolution encoded in h.264 you can expect about 
1200-1400kbps to work beautifully.)

 

So now things are starting to seem less groundbreaking – this is a 2mbps test 
video being streamed to 50 clients in the same room, with perfect or 
near-perfect line of sight to each. Total aggregate traffic is 100mbps on N/AC. 

 

I’m far too jaded by whitepapers, so I’ll keep to this assumption until Cambium 
gives us real numbers.

I was not thinking multicast.  Do you think this is multicast?

Not watching the video, but doing this with multicast is easy. 50 different 
7-25Mbps streams would be much more difficult.

I would be interested in seeing the same video showing them streaming 50 
football games at the same time.  Animations compress pretty tight.

cnPilot WiFi E400 indoor and E500 outdoor solutions demonstrate simultaneous 
video streaming to 50 clients. https://www.youtube.com/watch?v=SfP2D019JYw
