Apparently also tired of Shanghai’s molasses-slow internet, Shanghai’s Fudan University has reportedly developed a technology that allows a one-watt lightbulb to connect up to four computers to the internet at once, and over twenty times faster than normal:
According to the School of Information Science and Technology at Fudan University, researchers modulated Internet signals to a 1watt LED lamp. Under the light, four computers were able to access the Internet.
“A video program was successfully delivered between two computers at this speed in our experiment,” said Chi Nan, a professor from the University, who led the research.
Scientists reach record speed on Internet using light waves
The LED-based alternative to Wi-Fi, dubbed Li-Fi, or Light Fidelity, refers to a type of visible light communication technology that delivers a networked, mobile, high-speed communication solution in a similar manner to Wi-Fi.
The offline maximum speed reached 3.7 Gb per second which, scientists said, is the world’s fastest Internet access speed by LED light, while the average speed of a real-time system is up to 150 Mb/s.
Though if you’ve ever used internet in China, you’d imagine hooking your computer up to a wind turbine would be faster too. Currently, there are no videos or photos showing the technology in action, and experts state that more evidence is needed to verify the claims. If successful, however, we wonder if they could also use a lightbulb to generate the 1.21 gigawatts needed to power the DeLorean to go back to 2011 and smack China Telecom right after they falsely promised to bring Shanghai internet up to speed.
