Li-Fi working - The TeCake
By using Visible light Communication System, Scientists managed to transfer data at a rate of 224 Gbps (theoritical) in a lab test. The developed technology is named as Li-Fi (Light Fidelity).

In the era of competitive Internet speed, researchers have invented a new technology named as Li-Fi, which is claimed to provide a 100 times faster connection than the traditional Wi-Fi, we are currently using. Scientists reported that the new Li-Fi or Light Fidelity technology enabled them to achieve a theoretical lab test connection speed up to 224 Gbps. However, the practical data transfer speed is expected to be around 1 Gbps, which can even download a full HD movie within the seconds, says the Estonian startup, Velmenni.

The company is currently taking trials in their offices, explains that the high-speed data transfer rate is attained by the Visible Light Communication (VLC), which uses network LEDs that flicker incredibly fast. But the drawback here arises that for a flawless communication the system requires visible light, which resists it to communicate within the walls.

How Li-fi Works - The TeCake

Deepak Solanki, CEO of Velmenni reported that the fresh innovative technology could be rolled out in next tree to four years. However, scientists are planning to run both of the former and latter technologies in parallel due to the limitations. They claim that this will help in a better speed with a greater efficiency and security.

Professor Haas suggested in a 2011 TED Talk that it is further expected that the Li-Fi could be widely used if its infrastructure catches up, as the data is being transmitted through their lightbulbs. Explaining in detail, he said, “All we need to do is fit a small microchip to every potential illumination device and this would then combine two basic functionalities: illumination and wireless data transmission.”

“In the future we will not only have 14 billion light bulbs, we may have 14 billion Li-Fis deployed worldwide for a cleaner, greener and even brighter future.”
