A DATA TRANSFER SYSTEM USING LI-FI TECHNOLOGY

The present invention is related to a data transfer system using Li-Fi technology. Light Fidelity (Li-Fi) is a new technology that has been developed in the last couple of years and still needs further examination and trials to prove its perfection as a substitute for Wi-Fi technology. Li-Fi uses light as a medium of communication rather than traditional radio frequencies as in Wi-Fi. Li-Fi technology has the same essential features as Wi-Fi, such as being ideal for high-density wireless data coverage in a confined area and reducing radio interference issues. In this invention, a PC-to-PC wireless data transfer system is proposed based on Li-Fi technology. Data is transmitted from the transmitter PC via the light of an array of white LEDs connected to the Arduino UNO. The data is then received on the PC receiver using a photodiode connected to another Arduino UNO device to sense the light and interpret it in its original format.
