Harald Haas: Wireless data from every light bulb

http://www.ted.com What if every light bulb in the world could also transmit data? At TEDGlobal, Harald Haas demonstrates, for the first time, a device that could do exactly that. By flickering the light from a single LED, a change too quick for the human eye to detect, he can transmit far more data than a cellular tower -- and do it in a way that's more efficient, secure and widespread.

TEDTalks is a daily video podcast of the best talks and performances from the TED Conference, where the world's leading thinkers and doers give the talk of their lives in 18 minutes. Featured speakers have included Al Gore on climate change, Philippe Starck on design, Jill Bolte Taylor on observing her own stroke, Nicholas Negroponte on One Laptop per Child, Jane Goodall on chimpanzees, Bill Gates on malaria and mosquitoes, Pattie Maes on the "Sixth Sense" wearable tech, and "Lost" producer JJ Abrams on the allure of mystery. TED stands for Technology, Entertainment, Design, and TEDTalks cover these topics as well as science, business, development and the arts. Closed captions and translated subtitles in a variety of languages are now available on TED.com, at http://www.ted.com/translate.

IF ONLY WE CAN HOOK IT ON THE SUN!

7:45 The cameraman: "Oh man, I've gotta get some footage of this!" it's a lamp on a pedestal with a hole in it, dude.

[meeed023]

I'm so impressed , i like the idea

[SilasPiacenti]

@MrChannnnnnnnnnnnnnn Maybe on the Moon.

[hedgehobb]

I still believe Gamma rays should be used... HULK SMASH

[WirelessTortureDevi]

Thats crazy, soon it will be like the movie Demolition Man with the computer spitting out fail tickets only way worse.

[I3L4NK]

Amazing. I'll be damned if this isn't the future of wireless internet.

@ross817 Public Key encryption? Anyone?

@Neojhun i'm not really sure how your "no-one really uses it" is relevant.

If you need a 1000fps camera to capture the data you want, then you'll use a 1000fps camera. That tech is old & it's thus not a limitation.

I'm not giving you instructions on howto reproduce this technology in your basement with what you have lying around, i'm giving an example showing why crosstalk between different LEDs doesn't negatively effect the system.

@Neojhun cool, my bad , thx

[Neojhun]

@roidroid I said "about" yes you can get highspeed 1000FPS camera but no one realy uses it. So if most people are up to the 60 FPS mark. Light Data transmission is at the 10000Hz mark. They will never effect each other.

@habbitz I doubt it, light or IR data transmision is old tech. Some old phones and laptops have 26Kbs IR transiever. Those devices are tiny. This is just a amped up version of it. But the idea of using it for broadcasting is the genius. Because everywhere humans are active Light is there. Only problem is Day Light.
