LiFi (Light Fidelity) is a visible light communications system transmitting wireless internet communications at very high speeds via LED or infrared light that was first unveiled in 2011 and, unlike wifi, which uses radio frequency. The LiFi multiplies the speed and bandwidth of wifi, 3G and 4G with its band frequency of 200,000 GHz, versus the maximum 5 GHz of the wifi, is 100 times faster and can transmit much more information per second. (Refer to the Wifi)
Reference Definition by Wikipedia: Li-Fi (short for light fidelity) is wireless communication technology which utilizes light to transmit data and position between devices. The term was first introduced by Harald Haas during a 2011 TEDGlobal talk in Edinburgh. In technical terms, Li-Fi is a light communication system that is capable of transmitting data at high speeds over the visible light, ultraviolet, and infrared spectrums. In its present state, only LED lamps can be used for the transmission of visible light.
