Your Internet connection might one day be as simple as flicking a light switch. Researchers at Fudan University in Shanghai, China, have created an LED lightbulb that produces its own Wi-Fi signal, according to ZDnet.
With the help of a microchip, the one-watt "Li-Fi" lightbulb can connect up to four computers to the Internet simultaneously, at a speed of about 150 megabites per second. (In comparison, my home computer has a connection speed of about 20 mbps, so that's an insanely high speed increase.)
The Li-Fi lightbulb uses light frequencies instead of radio waves, and is a cheaper and more eco-friendly way of accessing the Web since it reportedly only uses 5% of the energy used by most Wi-Fi devices.
Researchers are presenting 10 lightbulb samples at the International Industry Fair in Shanghai next month and still have some kinks to work out: According to Dvice.com, they've encountered some design and manufacturing problems. Additionally, if the bulb becomes blocked of the light is turned off, the connection is lost. So don't throw out your router yet.
