back to article Forget Wi-Fi, boffins get 150Mbps Li-Fi connection from a lightbulb

Scientists in China are reporting great success in replacing traditional Wi-Fi radio traffic with Li-Fi, a system that uses the light signals from an LED lightbulb to provide a line-of-sight data stream. Li-Fi, or light fidelity, was developed by Professor Harald Haas at the University of Edinburgh, who was disenchanted with …
