LiFi (Light Fidelity) is a cutting-edge technology that uses visible light to communicate data wirelessly, like how Wi-Fi uses radio waves. Light Emitting Diodes (LEDs) are the principal source of light in this system for information transmission. To transmit data, the LED light blinks on and off very quickly, quicker than our eyes can detect. After then, a sensor records these light signals and transforms them back into data that can be used. Li-Fi (Light-Fidelity) is a fast communication technology that sends data by using light. Like Wi-Fi, it is speedier, enabling users to send and receive larger amounts of data more quickly. Using visible light communication (VLC), Li-Fi focuses on using LEDs to send multimedia data between two terminals. Wireless data transfer and illumination are combined in Li-Fi, which fits a tiny microchip into every conceivable illumination source. By 2022, the data transmission speed is expected to increase to 100 Mbps. Li-Fi can expand access to the internet and transform the telecom sector. It addresses issues with capacity, effectiveness, availability, and other aspects of wireless communication.
