Light Fidelity, known as LiFi, uses visible light from LED bulbs to transfer data much faster than radio wave-based WiFi.
Light Fidelity, also known as LiFi, which uses visible light from LED bulbs to transfer data much faster than radio wave-based WiFi, has been developed by China.
WiFi could become obsolete in a few years as Chinese scientists have developed a faster way of transmitting data via LiFi.
A 2015 test by a Chinese government ministry showed that LiFi can reach speeds of 50 gigabytes per second, at which a movie download can be completed in just 0.3 seconds.
