Underwater Data Communication Using Li-Fi Technology

Abstract

The demand for reliable underwater communication systems has increased rapidly due to advancements in marine research, underwater robotics, environmental monitoring, and defense applications. Conventional underwater communication techniques, such as radio frequency (RF) and acoustic communication, suffer from significant limitations including high attenuation, limited bandwidth, signal distortion, and high latency. These limitations reduce the efficiency of real‑time underwater data transmission and restrict the performance of underwater monitoring and exploration systems.Experimental observations indicate that Li‑Fi based communication performs effectively for short‑range underwater communication. The system demonstrates low latency, reduced power consumption, improved data transmission speed, and enhanced security compared to traditional methods. The results confirm that Li‑Fi technology is a promising solution for future underwater communication applications including oceanographic data acquisition, underwater robotics, and remote monitoring systems.
