Chinese Scientists Invent Lightbulbs That Emit Wi-Fi

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.

One of the perks of Li-Fi is that it's affordable. Have a lightbulb and a Li-Fi kit? Boom—you have internet. Chinese people are quickly replacing old fashioned incandescent bulbs with LEDs.

Of course, there are still a few technical details—mostly dealing with microchip design and manufacturing—that would need to fall into place before Li-Fi becomes ubiquitous. So for now, Li-Fi remains an experiment with a bright future.
