With the continuous rise in global internet usage, the need for dependable and high-speed connectivity has become more critical. Although Wi-Fi (Wireless Fidelity) is commonly used, it can become expensive and often suffers from reduced speed, especially when more than two routers are connected simultaneously. Light Fidelity (Li-Fi) presents a cutting-edge solution to these issues by enabling wireless communication through visible or infrared light, based on the principle of Visible Light Communication (VLC).This study proposes a system that facilitates the transmission of different data types--such as text, audio and images--using VLC technology. The data is sent via high-intensity LED arrays at the transmitting end, while a photodiode at the receiving end detects and converts the light signals back into data. The system's effectiveness is analyzed under varying conditions, including changes in transmission distance, light intensity, and signal quality.Li-Fi technology can deliver data at rates reaching up to 500 Mbps over short ranges using LED lights, or around 10 Kbps when standard lamps are used. Experimental findings validate the system's ability to transfer data efficiently under different environmental scenarios. Moreover, the concept is extended to demonstrate its potential in indoor location-based services, revealing its wide scope of application
