VLC system using LEDs for transmitting underwater information

The challenges of high latency and interference plaguing Radio Frequency (RF) communication have sparked a quest for alternative solutions. Visible Light Communication (VLC) emerges as a promising alternative due to its distinct advantages. Unlike RF communication, which requires separate configurations for transmission and reception of RF waves, VLC operates seamlessly, utilizing visible light for both transmission and reception. Light Emitting Diodes (LEDs) replace fluorescent lamps as a result of the solid-state lighting revolution, further encouraging the use of VLC. In contemporary discussions, there’s been a noticeable surge in interest surrounding the application of VLC within underwater settings, particularly for applications like oceanographic data collection and other underwater tasks. The collected data must be transmitted to an inland base station for further analysis, especially for time-critical applications in military and scientific domains. The aim is to analyse the performance of the RF with Underwater VLC (UVLC) link, with particular purpose of data speed and signal strength in under water environments. By strategically integrating acoustic and VLC technologies, the system attains high-speed data transmission capabilities alongside long-range communication capabilities. This research aims to address the complex challenges of underwater communication and provide insights into the most effective communication protocols and link combinations for real-time data streaming in underwater environments.
