Abstract: With the episodic increase of advancement in technology, wireless communication has become the need of the hour. The rate at which the use of wireless technology is being developed is tremendous. However, with the increase in usage, there has been unfortunately an increase in network complexity. In order to resolve the crisis of radio frequency spectrum, a newly developed technology has been proposed. This technology has been coined as Li-Fi: Light Fidelity. It is a technology, based on Visible Light Communication, which is used to transmit signals and data from one system to another with the help of a Led. The paper proposes a transmission system which will be responsible for transmitting audio signals from one system to another with the help of Li-Fi. Here a light emitting diode acts as the Li-Fi transmitter and photodiode acting as a Li-Fi receiver.The spontaneous switching of the Led enables propagation of signals through a wireless channel and is picked up by the receiving photodiode. The photodiode adhering to its functiontransforms the optical signals into electrical signals and therefore original data is retrieved and transferred. Additionally, with proposition to the system, a comparative study has been delineated with the already existing system.The existing system of networking and communications involve Wi-fi. The emergence and usage of Li-fi is necessary because it offers a substantially similar user experience to Wi-Fi except using the light spectrum. It is essential as it will able to meet up the connectivity demands of future as it is able to unlock unprecedented data and bandwidth
