Light Fidelity (LiFi) is a wireless optical networking technology that uses visible light from LED for data transmission. Unlike infrared-based systems, Visible Light Communication involves transmitting data using light visible to the human eye. LiFi work by flickering light at a rapid-fire rate, invisible to the human eye. To connect to a Li-Fi network, devices 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 (VLC) is that it works only when the device has a line of sight to the light transmitter. Light cannot penetrate walls as radio signals can, so drive-by hacking of wireless internet signals would be far more difficult.
