Now try Li-Fi, it's 100 times faster than Wi-Fi

Here's a good news for techies: Scientists have developed a wireless technology that transmits high-speed data using Visible Light Communication (VLC) and it is said to be more secure.

In a lab test conducted earlier this year, Li-Fi hit a speed of 224 giga bits per second making it a superfast alternative to Wi-Fi. Now the scientists have taken the technology out of the lab and started trying it in offices and industrial environments in Tallinn, Estonia.

Reports said they can achieve data transmission at 1 GB per second, which is 100 times faster than current average Wi-Fi speeds.

The Li-Fi technology was invented in 2011 by Harald Haas from the University of Edinburgh, Scotland. He demonstrated for the first time that by flickering the light from a single LED, he could transmit far more data than a cellular tower.

According to ScienceAlert, VLC is a medium that uses visible light between 400 and 800 terahertz (THz). It works basically like an incredibly advanced form of Morse code.

As light cannot pass through walls, it makes Li-Fi a lot more secure than Wi-Fi.

However, Anthony Cuthbertson, technology reporter at IB Times UK, says that Li-Fi will probably not completely replace Wi-Fi in the coming decades and the two technologies could be used together to achieve more efficient and secure networks.
