A new method of delivering data, which uses the visible spectrum rather than radio waves, has been tested in a working office.<\/p>\n

Li-fi can deliver internet access 100 times faster than traditional wi-fi, offering speeds of up to 1Gbps (gigabit per second).<\/p>\n

It requires a light source, such as a standard LED bulb, an internet connection and a photo detector.<\/p>\n

It was tested this week by Estonian start-up Velmenni, in Tallinn.<\/p>\n

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.<\/p>\n

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.<\/p>\n

Speaking to the International Business Times, chief executive Deepak Solanki said that the technology could reach consumers “within three to four years”.<\/p>\n

\"Tech<\/a><\/p>\n

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.<\/p>\n

His talk, which has now been watched nearly two million times, showed an LED lamp streaming video.<\/p>\n

Prof Haas described a future when billions of light bulbs could become wireless hotspots.<\/p>\n

One of the big advantages of li-fi is the fact that, unlike wi-fi, it does not interfere with other radio signals, so could be utilised on aircraft and in other places where interference is an issue.<\/p>\n

While the spectrum for radio waves is in short supply, the visible light spectrum is 10,000 times larger, meaning it is unlikely to run out any time soon.<\/p>\n

But the technology also has its drawbacks – most notably the fact that it cannot be deployed outdoors in direct sunlight, because that would interfere with its signal.<\/p>\n

Neither can the technology travel through walls so initial use is likely to be limited to places where it can be used to supplement wi-fi networks, such as in congested urban areas or places where wi-fi is not safe, such as hospitals.
