Abstract

Data transmission technology with radio frequency and fiber optics using frequency modulation (FM) techniques has been known for a long time. This technology facilitates the transmission of sound through an analog signal from the transmitter to the receiver. The development of technology using visible light that utilizes LED lights as senders of information is quite a lot done. In this study, the authors aim to implement a system of sending and receiving mp3 audio sounds by utilizing visible light from LED lights. Light Fidelity or commonly called Li-Fi is implemented using the modulation method and demodulation of FM frequency signals. From the test results it can be shown that this system has signal attenuation with an average of -27,972 dB at a maximum distance of 120 cm in a bright room. With a vertical angle of 25 ° and a horizontal angle of 0 °. The color of the LED lights is white, so it is suitable to be applied to every room.
