A new method of delivering data called Li-fi is can deliver internet access 100 times faster than Wi-fi, offering up to 1Gbps requiring a light source, as LED, internet connection and a photo detector.
Velmenni's invention has been tested in the laboratory and have shown theoretical speeds of up 224Gpbs.
A big advantatge of li-fi is that it does not interfere with other radio signals so it could be utilised on aircraft and other places. It can't also run out any time soon because the visible light spectrum is 10,000 times larger than radio waves. The problem is that it cannot be deployed outdoors in direct sunlight.

So, li-fi can be used in limited places to supplement wi-fi networks, as in urban areas or places where wi-fi is not so safe.
