Forget Wi-Fi. Meet the new Li-Fi Internet | Harald Haas
TED
▻https://www.youtube.com/watch?v=iHWIZsIBj3QLi-Fi
▻https://en.wikipedia.org/wiki/Li-FiLi-Fi is a bidirectional, high-speed and fully networked wireless communication technology similar to Wi-Fi. The term was coined by Harald Haas and is a form of visible light communication and a subset of optical wireless communications (OWC) and could be a complement to RF communication (Wi-Fi or cellular networks), or even a replacement in contexts of data broadcasting.
It is wire and UV visible-light communication or infrared and near-ultraviolet instead of radio-frequency spectrum, part of optical wireless communications technology, which carries much more information and has been proposed as a solution to the RF-bandwidth limitations.

Li-fi 100 times faster than wi-fi
▻http://www.bbc.com/news/technology-34942685
A new method of delivering data, which uses the visible spectrum rather than radio waves, has been tested in a working office.
Li-fi can deliver internet access 100 times faster than traditional wi-fi, offering speeds of up to 1Gbps (gigabit per second).
It requires a light source, such as a standard LED bulb, an internet connection and a photo detector.[...]
Laboratory tests have shown theoretical speeds of up to 224Gbps.

The term li-fi was first coined by Prof Harald Haas from Edinburgh University, who demonstrated the technology at a Ted (Technology, Entertainment and Design) conference in 2011.
