Incredibly it can all work off a simple LED lightbulb, according to IBTimes.
Li-Fi, which stands for Light-Fidelity, sends data through a beam of light rather than via radio waves and can send information as fast as 3GB per second.
That means you could download a whole film in HD in the blink of an eye.
It is believed this speed could even be tripled by splitting the beams into channels.
The inventor of the technology Professor Harald Haas, of the University of Edinburgh, gave a TED Talk about his idea back in 2011.
Very interesting stuff...
