When you think about broadband connections, you usually picture radio airwaves or wires, not ambient light. But the emerging field of LED broadband (sometimes dubbed Li-Fi) aims to turn your light bulbs into data transmitters by subtly manipulating the rate they flicker. One of the organizations researching such optical communications technology, Germany’s Fraunhofer, has hit a new milestone: a lighting system that could deliver up to 3 Gbps.
This would be really great! it opens unlimited possibilities!
