How about downloading a movie from an LED lamp in your home or streaming music from an illuminated bus shelter? ‘LiFi’, a forthcoming alternative to WiFi technology, will allow us to do just that, transferring large amounts of data using various forms of light.

The light-based communications technology, developed by Edinburgh University’s Harald Haas, uses the visible light portion of the electromagnetic spectrum to transmit information at high speeds. In fact, recent scientific tests of the technology have shown it is possible to achieve data transmission speeds of 1GB per second. At 100 times faster than the average Wi-Fi speed, it promises change for how people use the internet in the future.
