Light Fidelity, also known as LiFi, which uses visible light from LED bulbs to transfer data much faster than radio wave-based WiFi, has been developed by China. WiFi could become obsolete in a few years as Chinese scientists have  developed a faster way of transmitting data via LiFi. 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.
In previous studies, carbon dots were limited to the emission of lights such as blue and green. The new nanomaterial that Qu’s team has developed can emit all light visible to the human eye, which is a breakthrough in the field of fluorescent carbon nanomaterial. Qu said this is significant for the development of LiFi, which he expects to enter the market in just six years.

I no no why person dey talk China wey as I done already dey use LiFi for USA,,,., nobi lie for united state here many ppl dey use am browse., but I no no weda Benin republic go get am cos I go leave Aba town tomorrow
