250x faster than 'superfast' broadband: UK researchers in 'Li-Fi' connectivity breakthrough
Internet connectivity through light fidelity (Li-Fi) has reached a new milestone, according to UK researchers.
A team of researchers from the universities of Oxford, Cambridge, Edinburgh, St Andrews and Strathclyde working on the Ultra-Parallel Visible Light Communications Project claim to have reached record data transmission speeds of 10.5 Gbit/s via Li-Fi.
Li-fi works by utilising specialised LED bulbs to transmit data through parallel streams of light that are undetectable to the human eye.
"If you think of a shower head separating water out into parallel streams, that's how we can make light behave," said Professor Harald Haas, a German physicist and one of the project leaders at the University of Edinburgh.
