Li-Fi is a wireless technology that transmits high-speed data using visible light communication and will be available in the coming months. With scientists achieving speeds of 224 gigabits per second in the lab using Li-Fi earlier this year (that's equivalent to 18 movies of 1.5 GB each being downloaded every single second), the potential for this technology to change everything about the way we use the Internet is huge.

Scientists have now taken Li-Fi out of the lab for the first time, trialing it in offices and industrial environments in Tallinn, Estonia, reporting that they can achieve data transmission at 1 GB per second - that's 100 times faster than current average Wi-Fi speeds.

The technology uses Visible Light Communication, a medium ...
