How LiFi Technology Works?
LiFi technology operates like magic, transforming ordinary light sources into data carriers. When data is to be transmitted, an LED light bulb flickers at incredibly high speeds, too swift for the human eye to detect. These fluctuations encode data from a light-sensitive receiver (e.g., a photodiode) on the receiving end. The receiver then decodes the changes in light intensity, converting them back into usable data.
This ingenious process enables seamless wireless communication with remarkable speed and security, as light cannot penetrate walls like radio waves. Li-Fi opens the door to a dazzling future where our devices dance in tune with the flicker of light.
