Li-Fi, short for Light Fidelity, is a wireless communication technology that uses light to transmit data instead of radio waves like Wi-Fi does. It works by encoding data into light pulses using LEDs and transmitting them to a receiver device that has a photodetector. This device then decodes the light signals back into data. Li-Fi offers potential benefits such as higher data transfer rates, increased security, and reduced electromagnetic interference compared to Wi-Fi. However, Li-Fi has some
