Li-Fi works by flickering light at a rapid-fire rate, invisible to the human eye. To connect to a Li-Fi network to Li-Fi network, a device must be equipped with the capability to recognize the LED light signals and use them to transfer data.

Light cannot penetrate walls as radio signals can, so drive of wireless internet signals would be far more difficult.
