Light Fidelity (Li-Fi) is a high-speed and bidirectional wireless technology that uses light through light emitting diodes (LEDs) to deliver fully networked communication. It transmits data over the electromagnetic spectrum similar to Wi-Fi. However, unlike Wi-Fi, it utilizes visible light and not radio waves.Visible light communications work by switching the current to the LEDs at a rapid rate, making it unnoticeable to the human eye. Also, visible light communication is harmless for people ... Read more
