A group of Chinese scientists at Shanghai’s Fudan University have a
bright idea: A lightbulb that produces its own Wi-Fi signal. According to Xinhua, the technology is called Li-Fi, and the prototype actually works better than the average connection in China. As many as four computers placed near a Li-Fi bulb can connect to the net, using light frequencies rather than the usual radio waves. The bulb is embedded with a microchip that produces a signal, yielding rates as fast as 150 mbps-far faster than typical connection speeds in China, and about three times faster than the speed I’m getting right now.
