What is Li-Fi And how to work ?
Li-Fi stands for " Light Fidelity " and refers to a wireless communication technology that uses light waves instead of radio waves to transmit data. It is a form of visible light communication (VLC) that uses light-emitting diodes (LEDs) to transmit data. The basic principle behind Li-Fi is that data is transmitted by varying the intensity of the light emitted by an LED bulb. The data is encoded in binary format (0s and 1s) and the LED is turned on and off rapidly (in the range of millions of times per second) to transmit the data. This rapid on-off cycle is imperceptible to the human eye, but can be detected by a photodiode or similar light sensor. Li-Fi has several advantages over traditional Wi-Fi, including higher data transfer rates, greater bandwidth, and greater security. Li-Fi can achieve data transfer rates of up to 224 gigabits per second, which is much faster than the current Wi-Fi standards. Li-Fi also uses a different part of the electromagnetic spectrum than W...
