What does Li-Fi mean?

Li-Fi is a wireless optical network technology. Li-Fi uses visible light from LED for data transmission. So in unlike infrared based systems, visible light communication involves to the transmitting data using light visible to the human eye. Li-Fi work by flickering light at a rapid-fire rate, invisible to the human eye. To connect to a Li-Fi network to a Li-Fi network, a device must be equipped with the capability to recognize the LED light signals and use them to transfer data. A unique security aspect of visible light communication is that it works only when a device has a line of sight to the light transmitter. Light cannot penetrate walls as radio signals can, so drive of wireless internet signals would be far more difficult.
