Breakthrough in wireless technology using light

Wireless Light Fidelity (LiFi) wireless technology, launched in the next six years, can bring many benefits to life.

It only takes 0.3 seconds to load a movie on the Internet to the computer? The hitherto unmistakable sound of the present is likely to come true soon after the introduction of the Light Fidelity (LiFi) wireless technology for the next six years.

Chinese scientists have come a long way toward developing LiFi after successfully producing colorful fibrous carbon (F-CDs) - a fluorescent carbon nanotube that has the advantage of being safe and faster.

Most LiFi research projects now use rare earths to provide light to LiFi in data transmission.

According to scientists from the Institute of Optometry, Mechanics and Physics Changchun of the Chinese Academy of Sciences, this is a simple way to make simple, cost-effective materials such as ure. Meanwhile, rare earths are believed to be more durable but may reduce the speed of LiFi transmission.

In addition to the speed of transmission, F-CDs can display all of the light that the human eye sees. In previous studies, F-CDs have limited exposure to light such as blue and green.

LiFi uses visible light from the LED and can transmit data faster than WiFi technology using radio waves. Results from the China test conducted in 2015 show that the LiFi can reach speeds of 50 GB / sec.
