This would be really great! it opens unlimited possibilities!

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.
Fraunhofer’s Heinrich Hertz (yes, that Hertz) Institute said it has developed components in the lab that will allow off-the-shelf LED lights to transmit data at a rate of 1 Gbps on a single frequency. Since most commercial LEDs support three frequencies (or colors) of visible light, that gives the system a total capacity of 3 Gbps.
The institute has achieved this, in part, by expanding the size of each frequency transmission band from 30 MHz to 180 MHz. Basically, Fraunhofer has developed…
