Li-Fi - 100 times faster than Wi-Fi
This new technology is going to change the internet era!
"One of the big advantages of Li-Fi is the fact that, unlike Wi-Fi, it does not interfere with other signals, so could be utilized on aircraft and in other places where interference is an issue."
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. 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.
Speaking to the International Business Times, chief executive Deepak Solanki said that the technology could reach consumers "within three to four years". 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. His talk, which has now been watched nearly two million times, showed an LED lamp streaming video. Prof Haas described a future when billions of light bulbs could become wireless hotspots.
