Li-Fi

= an alternative to Wi-Fi that transmits data using the spectrum of visible light

Description

"Li-Fi, an alternative to Wi-Fi that transmits data using the spectrum of visible light, has achieved a new breakthrough, with UK scientists reporting transmission speeds of 10Gbit/s – more than 250 times faster than ‘superfast’ broadband.

The fastest speed previously reported was 3Gbit/s, achieved earlier this year by the Fraunhofer Heinrich Hertz Institute in Germany. Chinese researchers also claimed this month to have produced a 150Mbp/s connection, but some experts were doubtful without seeing further proof.

The term Li-Fi was coined by Edinburgh University's Prof Harald Haas during a TED talk in 2011though the technology is also known as visible light communications (VLC)."
