Description: Kako bi bilo, če bi vsaka žarnica omogočala tudi prenos podatkov? Harald Haas nam na dogodku TEDGlobal premierno predstavlja napravo, ki to omogoča. S hitrim preklapljanjem ene same LED-sijalke, s spremembo, ki je oko ne zazna, lahko prenašamo več podatkov kot bazna postaja mobilne telefonije -- bolj učinkovito, bolj varno in bolj razširjeno.

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.
