To GOOD : ” One German physicist, Harald Haas, has come up with a solution he calls “data through illumination” (…) by sending data through an LED lightbulb that varies in intensity faster than the human eye can follow.”
” It’s the same idea behind infrared remote controls, but far more powerful. Haas says his invention, which he calls D-Light, can produce data rates faster than (…) your average broadband connection. ”
” He envisions a future where data for laptops and smartphones is transmitted through the light in a room. And security would be a snap—if you can’t see the light, you can’t access the data. “
