Idea: LEDs as Dark Mesh Networks
Nice. This is cool because it can empower teams to share information, securely, in any room where they can control the lighting. And, since LED pucks are extremely mobile, you can do this on an ad hoc basis.
By contrast [ to radio ], visible-frequency wireless has all the bandwidth one could want. The signal would be generated in a room by slightly flickering all the lights in unison. No one would be bothered by this because the rate of modulation would be millions of times faster than a human eye can see. Since visible light can’t go through walls like radio, there would be no unwanted interference from stray signals and less worry of outside hackers.
