Transfer Data from PC to PC Based on Li-Fi Communication Using Arduino

Abstract

Light Fidelity (Li-Fi) is a new technology that has been developed in the last few years and still needs more investigation and experiments to prove its perfection to be an alternative solution for wireless fidelity (Wi-Fi) technology. Li-Fi utilizes light as a medium of communication instead of traditional radio frequencies as in Wi-Fi. Li-Fi technology has the essential features compared to Wi-Fi, such as its ideal for high-density wireless data coverage in a confined area and reducing radio interferences issues. In this paper, a PC-to-PC wireless data transfer system is proposed based on Li-Fi technology. Data is transmitted from transmitter Pc via the light of an array of high-power white LEDs connected to 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 decode it to its original format. This work aims to improve the transmission and reception mechanism by increasing the data bit rate. After experimenting, the evaluation results showed that the data bit rate was improved using the proposed transmission mechanism and reached up to 147 bps with an accuracy of 100%, over 20 cm as a distance between the transmitter and receiver.
