Li-Fi is a wireless communication technology that uses light to transmit data. It is similar to Wi-Fi, but uses visible light instead of radio waves to transmit data. Li-Fi has the potential to provide high-speed, wireless data connections that are more secure and efficient than Wi-Fi.
Some of the emerging trends in Li-Fi include the use of visible light communication (VLC) for data transmission, the use of organic light-emitting diodes (OLEDs) for data display, and the use of nanoparticles for data storage.
