Chinese scientists have made a breakthrough in replacing WiFi with faster LiFi

Almaty. October 5. Silkroadnews - Chinese scientists have made a breakthrough in replacing WiFi with faster LiFi, People’s Daily reported.
“Chinese scientists have made a breakthrough 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,” the report said.
It explains that compared to WiFi technology with its wave-based operation, LiFi’s ultra-fast communication technology uses visible light from LED bulbs for data transmission. While most of today’s research focuses on use of rare-earth materials to provide the light for LiFi, a group of Chinese scientists developed F-CDs, an alternative fluorescent carbon nanomaterial that proved its higher safety and speed.
“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,” the agency quoted saying by Qu Songnan, an associate researcher at Changchun Institute of Optics, Fine Mechanics and Physics, the Chinese Academy of Sciences, leading the research.
According to him, the long life of rare-earth elements reduces the speed of LiFi transmission. F-CDs, on the contrary, increases it.
In previous studies, as it is reported, 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. Such a move, according to the developer, is important for LiFi technology development to enter the market in six years.
“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,” the publication reads.
