Here's a bright idea: instead of radio waves, use light to get online.
妙点子的原理是这样的:不利用无线电波,而是利用光线来上网|7q.W;JuQ~-roZo!7。
Unlike wi-fi, or wireless fidelity, so-called “li-fi” transmits data through variations in light intensity.
与wi-fi,或熟知的无线保真不同,所谓的li-fi通过光强度的变化传输数据@,SuR2JKHz。
Researchers in China recently showed that, using a one-watt LED bulb, li-fi could connect four computers to the Internet at data transfer rates up to 150 megabits per second.
最近中国的研究者们发现,使用一个1瓦特的LED灯泡,li-fi就可以以带宽150兆/秒的传输速率连接4台电脑接入互联网blH#qUr#ZWGiZX9Q^。

Earlier this year, German scientists sent data at three Gigabits per second using LED lamps, in controlled conditions in their lab.

On the plus side, the visible light spectrum can handle way more traffic than wi-fi's already crowded radio spectrum.

We may someday look back at wi-fi as technology from the dark ages.
