A new type of wireless internet technology has been developed that could provide a connection that’s 100 times faster than traditional WiFi. 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 tech is called LiFi, and was tested by an Estonian start-up called Velmenni, who are currently trialling it in offices.
Professor Harald Haas, from the University of Edinburgh, pioneered the technology and coined the term LiFi in 2011, but this is the first time it’s been used in a ‘real world’ setting. LiFi is transmitted through our lightbulbs, as Professor Haas suggested in a 2011 TED Talk.
In the future we will not only have 14 billion light bulbs, we may have 14 billion LiFis deployed worldwide for a cleaner, greener and even brighter future.
However, due to LiFi’s limitations, it would be likely to run in parallel with existing technology to increase a network’s speed and efficiency.
