LiFi which means Light Fidelity is a futuristic development which according scientists globally will replace WiFi due to the super speed it wields, a speed WiFi(Wireless Fidelity).

LiFi is new development that will excite all smartphone and pc users because it it's promise to make our gadgets a lot more faster for communication.
Unlike WiFi which uses radio waves for its operations, LiFi uses Visible Light Communications (VLC) system
running wireless communications travelling at very high speeds.

It uses ordinary lights we see in our everyday lives, lights like the ones in our offices, those in street lights along the road or even our homes.

LiFi makes use of Visible light which can be seen in LED bulbs to transfer data, unlike WiFi which uses radio waves and it(LiFi) could be 100 times faster than Wi-Fi.

Different scientists all over the world are currently to make this project come to reality. Hence, Chinese scientists have come closer to developing this faster wireless communication channel that would be accessible to members of the public in the next six years.

They have already made progress in creating full-colour emissive carbon nanomaterial dots (F-CDs) which would be able toprovide light for data transmission. The latest research that is currently ongoing in regards to Li-Fi, uses rare earthly materials to create,emitte or provide light, but Chinese experts have come up with another option, F-CDs, a fluorescent carbon nanomaterial to provide light.
According to the Chinese scientists, this method is safer, reliable and faster. Although, “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,” Qu Songnan, an associate researcher at Changchun Institute of Optics said.

Qu further added that this breakthrough this essential in the development of Li-Fi which he anticipates will enter the market in the next six years.

According to a test carried out by Chinese scientists in year 2015, LiFi can reach speeds of 50 Gigabytes per second. A renowned scientist named Harald Haas of the University of Edinburgh first brought up the idea or should I say dicussion in the 2011 Ted talk, a video which has been viewed for over 2.2 million times.
Ever since then, it began to make wave across the whole world. Now as we speak companies in countries like Russia and Mexico are presently making Technologies based on LiFi.
