Li-Fi : 100 times faster than Wi-Fi

A new type of wireless internet technology has been developed that could provide a connection that’s 100 times faster than traditional WiFi. The tech is called LiFi, and was tested by an Estonian start-up called Velmenni, who are currently trialling it in offices.


LiFi has proved capable of sending data at speeds of up to 1GBps around 100 times faster than most current Wi-Fi connections. At speeds like this, albums, high-definition films and even video games could be downloaded in a matter of seconds. The speed is down to the way in which it transmits data — by using Visible Light Communication (VLC), data is sent between networks by LED lights that flicker incredibly fast. 

The technology does have one major limitation — because it relies on visible light to work, it can’t pass through walls. However, this makes the network much more secure. The dramatically increased speeds make it a big improvement on current technology for some applications as well.
