According to a team of UK researchers internet connectivity through Light fidelity (Li-Fi) has achieved new milestone.

A team of researchers from the universities of Oxford, Cambridge, Edinburgh, St Andrews and Strathclyde working on the Ultra-Parallel Visible Light Communications Project claims to have reached data transmission speeds of 10.5 Gbit/s via Li-Fi, a new record.

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, one of the project leaders at the University of Edinburgh. The team used micro-LED bulb to transmit 3.5 Gbits/s over the each of primary colors red, green and blue.

Also this technology could help to achieve low cost wireless internet in a secure manner as light is unable to pass through walls. “All we need to do is fit a small microchip to every potential illumination device and this would then combine two basic functionalities: illumination and wireless data transmission.” said professor Haas.
