A new method of delivering data, which uses the visible spectrum rather than radio waves, has been tested in a working office [bbc.com].

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.

It was tested this week by Estonian start-up Velmenni, in Tallinn.

Velmenni used a li-fi-enabled light bulb to transmit data at speeds of 1Gbps. Laboratory tests have shown theoretical speeds of up to 224Gbps.

It was tested in an office, to allow workers to access the internet and in an industrial space, where it provided a smart lighting solution.

It doesn't penetrate walls, which can be a good thing where too many wi-fi nodes compete.
