From the Ted Talk by Harald Haas: Wireless data from every light bulb

Unscramble the Blue Letters


What we have done is we have developed a technology with which we can furthermore replace the rteome control of our light bulb. We transmit with our technology, not only a slinge data stream, we transmit tandushos of data streams in plaalrel, at even higher speeds. And the technology we have developed — it's called SIM OFDM. And it's spacial mutalooidn — these are the only technical terms, I'm not going into daitels — but this is how we eebnlad that light source to trsimant data.

You will say, "Okay, this is nice — a sdile created in 10 minutes." But not only that. What we've done is we have also dpevoleed a demonstrator. And I'm showing for the first time in plibuc this visible light demonstrator. And what we have here is no ordinary desk lamp. We fit in an LED light bulb, worth three U.S. dollars, put in our signal processing technology. And then what we have here is a little hole. And the light goes through that hole. There's a receiver. The receiver will convert these little, subtle changes in the aitdmplue that we create there into an electrical sgnail. And that signal is then converted back to a high-speed data stream. In the future we hope that we can integrate this little hole into these smart phones. And not only integrate a photo detector here, but maybe use the camera inside.

Original Text


What we have done is we have developed a technology with which we can furthermore replace the remote control of our light bulb. We transmit with our technology, not only a single data stream, we transmit thousands of data streams in parallel, at even higher speeds. And the technology we have developed — it's called SIM OFDM. And it's spacial modulation — these are the only technical terms, I'm not going into details — but this is how we enabled that light source to transmit data.

You will say, "Okay, this is nice — a slide created in 10 minutes." But not only that. What we've done is we have also developed a demonstrator. And I'm showing for the first time in public this visible light demonstrator. And what we have here is no ordinary desk lamp. We fit in an LED light bulb, worth three U.S. dollars, put in our signal processing technology. And then what we have here is a little hole. And the light goes through that hole. There's a receiver. The receiver will convert these little, subtle changes in the amplitude that we create there into an electrical signal. And that signal is then converted back to a high-speed data stream. In the future we hope that we can integrate this little hole into these smart phones. And not only integrate a photo detector here, but maybe use the camera inside.
