‘Li-fi’ via LED light bulb data speed breakthrough

UK researchers say they have achieved data transmission speeds of 10Gbit/s via “li-fi” – wireless internet connectivity using light. The researchers used a micro-LED light bulb to transmit 3.5Gbit/s via each of the three primary colours – red, green, blue – that make up white light. This means over 10Gbit/s is possible. Li-fi is an […]
