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 radio as a data transmission tool. Using light instead of radio opens up 10,000 times more available spectrum than radio ? and it's highly energy efficient compared to radio towers that use most of their power for cooling and only five per cent for data transmission.
