Interesting Fact - Technology

According to research carried out by the Ultra Parallel Visible Light Communications project, a joint venture between the universities of Oxford, Cambridge, Edinburgh, St Andrews and Strathclyde, and funded by the Engineering and Physical Sciences Research Council wireless transmission reaching speeds of 10Gbit/s – more than 250 times faster than ‘superfast’ broadband is possible using converted LED lightbulbs.

(The technology, cleverly called Li-Fi by Edinburgh University's Prof Harald Haas, would enable existing LED light bulbs to be converted to transmit Li-Fi signals with a single microchip.  The
bulbs would have to be kept on to transmit data, but they could be dimmed to the point that they were not visible to humans, and would be more secure than Wi-Fi, as hackers would be unable to access unsecured internet connections from out of sight of the transmitter.)
