Lightbulbs Could Replace Wi-Fi Hotpsots


Hvis man kan anvende den eksisterende teknologi og de eksisterende infrastrukturer til at udbrede ny teknologi og ny infrastruktur står man måske med den næste store teknologiske revolution. Internet i de elektriske stikkontakt var på tale for nogle år siden, men fik aldrig det store gennembrud som det næsten fortjente.

If you can use existing technology and existing infrstructures to spread new technology and new infrastructures you might be standing on the edge to the next technological revolution. Some years ago some people got the great idea of distributing the internet in the existing electrical wires - sadly it never got the success it deserved.

"Imagine if your computer, iPhone, TV, radio and thermostat could all communicate with you when you walked in a room just by flipping the wall light switch and without the usual cluster of wires," said BU Engineering Professor Thomas Little. "This could be done with an LED-based communications network that also provides light - all over existing power lines with low power consumption, high reliability and no electromagnetic interference. Ultimately, the system is expected to be applicable from existing illumination devices, like swapping light bulbs for LEDs."
