Scientists Smash the Li-Fi Data Record, Achieving Speeds of 10Gbit/s If the hype is to believed, Li-Fi could be the next Wi-Fi . And if that's the case, then we're excited—because a team of researchers has just smashed the record for visible light data transmission, pushing it to a staggering 10Gbit/s. A team of researchers from the universities of Edinburgh, St Andrews, Strathclyde, Oxford, and Cambridge, all in the UK, have used a micro-LED light bulb to transmit 3.5Gbit/s across each of the three primary colours, red, green, and blue. Add that up, and it means that they can transfer 10Gbit/s across the three channels . The LED bulbs, developed at the University of Strathclyde, allow streams of light to be beamed in parallel, reports the BBC . Each beam carries a seperate data stream, each one encoded using digital modulation— Orthogonal Frequency Divisional Multiplexing for the true nerds—to produce millions of changes in light intensity per second. ...
