Currently, wireless communication technologies such as Wi-Fi and Bluetooth are widely used in our daily lives. Their wireless communication technology uses radio waves and uses frequencies allocated to each country. However, this method has problems such as limitations and interference with radio frequency (RF), security, and high cost. The Light-Fidelity (Li-Fi) method, which can solve these problems, has emerged as an alternative. Because the Li-Fi communication method uses visible light, its availability, bandwidth, security, and efficiency are superior to Wi-Fi. In this paper, the actual usability of Li-Fi was confirmed by implementing an audio system using the Li-Fi wireless communication method. The proposed system designed a modulation unit that converts the audio signal into an optical signal, and a demodulation unit that converts the optical signal back into an electrical signal and transmits it to the speaker. Additionally, an audio amplifier was added to amplify the signal. LED was used as a light ...
