LIFI-BASED WIRELESS AUDIO TRANSMISSION STYSTEM

Light Fidelity (Li Fi) technology enables high speed wireless communication using visible light, offering an alternative to traditional radio- frequency methods like Wi-Fi and Bluetooth.The proposed system transmits audio signals via modulated LED light, which are then received by a photodiode and converted back into sound. This method supports low-cost, energy-efficient, and secure communication, ideal for short range indoor applications like classrooms, hospitals.Advantages include high bandwidth, low latency, data security (as light is c.onfined to the room), and immunity to electromagnetic interference This audio This Li-Fi audio system presents a cost-effective and energy- efficient solution for short-range wireless audio transmission with potential applications in public announcements, multimedia streaming, and smart home device. Additionally, it offers a safer communication environment in sensitive areas where radio frequency signals might cause interference. As Li-Fi technology evolves, it could also play a significant role in the Internet of Things (IoT), enabling faster and more secure data transfer between connected devices.
