What is Li-Fi Li-Fi is the transmission of wireless data by using visible light as a medium of communication. Also known as Light Fidelity, Li-Fi uses subtle fluctuations in LED light to transmit data from the transmitter to the receiver. To encode the data, the LED light is switched on and off at an imperceptible speed creating slight fluctuations that is invisible to the naked eye. These fluctuations generate binary codes that are transmitted to the receiver which decodes the data back into digital form. There are two main components of a Li-Fi system: A transmitter that is often a high brightness LED light a receiver which is often a photodiode fitted into the receiver to convert light back into digital data. Li-fi technology is much faster as compared to the traditional Wi-Fi technology. It is capable of transmitting data up to 100 Mbps. In some cases, by using parallel…
