Description: Što kad bi svaka žarulja na svijetu također mogla prenositi podatke? Na skupu TEDGlobal, Harald Haas po prvi puta demonstrira uređaj koji može upravo to. Treperenjem svjetlosti iz jedne LED žarulje, brzinom prevelikom da bi to ljudsko oko zabilježilo, on prenosi puno više podataka od mobitelskog tornja -- i čini to na učinkovitiji, sigurniji i rasprostranjeniji način.

By harnessing the power of LED light bulbs, data can be transmitted using visible light, offering an alternative to crowded and inefficient radio waves. With 14 billion light bulbs already installed worldwide, this approach accesses a spectrum 10,000 times larger than what is currently used for wireless communication. A single LED lamp, modulated faster than the human eye can detect, can stream high-definition video and provide fast, secure connectivity. This method dramatically increases capacity, slashes energy waste, and protects privacy by confining data to illuminated spaces.
