Abstract: A Li-Fi-based optical communication system is proposed that overcomes the vulnerabilities of conventional RF communication links. The system uses light instead of radio signals to enable secure and reliable line-of-sight communication. By mounting the Li-Fi transmitter (213) on a __ _ mobile drone platform, the system overcomes the limitations of static transmitter infrastructure. An intelligent control system allows for both AI and manual control of the mobile drone via a front-end interface, implemented using embedded platforms such as the Raspberry Pi (205) and ESP32-C3 Mini microcontroller (201). Furthermore, secure optical communication is facilitated through the transmission of Morse code signals that are decoded in real time using an analog-to-digital converter, specifically the MCP3008 ADC (204). The system utilizes low-power-consuming and lightweight components like the ESP32-C3 Mini (201) and Raspberry Pi (205), allowing for space-efficient installation. In the transmitter and receiver modules, optical signals are strengthened and finely adjusted using a coherent laser source and optical components such as collimating or Fresnel lenses, powered by a compact energy source including a solar panel (203). Additionally, the system supports multiple encoding schemes for data transmission and logs flight parameters, communication performance, and control behaviour. Due to its mobile nature, the system is capable of maintaining and establishing an uninterrupted communication link, effectively overcoming line-of-sight limitations typically associated with Li-Fi systems, while ensuring reliable and near lossless transmission even in the presence of interference.
