President Xi Jinping was shown LiFi at the China International Import Expo in Shanghai, where the technology was selected to showcase UK innovation. The LiFi light bulb presented to the President is the first of its kind and was created by pureLiFi a company spun-out of the School of Engineering in 2012 to develop the technology.
Li-Fi creates a faster, more secure and energy efficient connection than Wi-Fi, by using light waves instead of existing radio technology. Demand for wireless internet access is in danger of overloading the amount that can currently be supplied by Wi-Fi. Li-Fi has no such limitations and could enable this capacity crisis to be overcome.
