Chinese Scientists To Replace WiFi With LiFi

Chinese scientists has developed a faster way of transmitting data replacing WiFi with WiFi.

The Chinese news agency Xinhua reported the breakthrough by the scientists in creating full-color emissive carbon dots (F-CDs), which brings them one step closer to developing a faster wireless communication channel that could be available in just six years.

Light Fidelity, known as LiFi, uses visible light from LED bulbs to transfer data much faster than radio wave-based WiFi.

A 2015 test by a Chinese government ministry showed that LiFi can reach speeds of 50 gigabytes per second, at which a movie download can be completed in just 0.3 seconds.

While most current research uses rare earth materials to provide the light for LiFi to transmit data, a team of Chinese scientists have created an alternative — F-CDs, a fluorescent carbon nanomaterial that proves to be safer and faster.

“Many researchers around the world are still working on this. We were the first to successfully create it using cost-effective raw materials such as urea with simple processing,” said Qu Songnan, an associate researcher at Changchun Institute of Optics, Fine Mechanics and Physics, the Chinese Academy of Sciences, which leads the research.

Qu said rare earth has a long lifespan which reduces the speed of LiFi transmission. However, F-CDs enjoy the advantage of faster data transmission speeds.
