Li.Fi o Comunicazioni a Luce Visibile / VLC

Li-fi, also known as visible light communications (VLC), at these speeds would be faster - and cheaper - than the average Chinese broadband connection.

 Chi Nan, IT professor at Shanghai's Fudan University told Xinhua News.
A one-watt LED light bulb would be enough to provide net connectivity to four computers, researchers say.
But experts told the BBC more evidence was needed to back up the claims.
In 2011, Prof Harald Haas, an expert in optical wireless communications at the University of Edinburgh,demonstrated how an LED bulb equipped with signal processing technology could stream a high-definition video to a computer.
