Name: Harald Has (Harald Haas): Bežični podaci iz svake sijalice

Description: Šta ako svaka sijalica na svetu može da prenosi i podatke? Na TEDGlobalu, Harald Has demonstrira, prvi put, uređaj koji može baš to. Treperenjem svetla jedne LED sijalice, prebrzom za ljudsko oko koje ne može to da detektuje, on će preneti više podataka od bazne stanice mobilne telefonije -- i to na način koji je mnogo efikasniji, sigurniji i šire rasprostranjen.

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.
