Wired or wireless network has become the essential way to use the Internet and complete people’s task these days. As the number of people accessing the wireless network increases, it gets complicated to rely on an incorrupt signal due to the jammed airwaves. Though Wi-Fi delivers a speed up to 1300 Megabits per second, it is not adequate to hold all the users. To redress this drawback of Wi-Fi, a new concept is being introduced called as Li-Fi, which provides a speed up to 224 Gigabits per second. This is very analogous to Wi-Fi. The major disparity is that visible light is used by Li-Fi and radio frequency is used by Wi-Fi to transmit data. In this project an Android application is created to transfer binary data from one device to another device through Li-Fi, whereas for audio transfer, a hardware setup is implemented using LED, solar cell, and speaker.
