Underwater Communication

Underwater communication refers to the exchange of information between devices or organisms beneath the surface of the water, primarily using sound. Since radio waves don't travel well underwater, acoustic signals—like sonar—are used instead. These sound waves can travel long distances and carry data such as messages or navigation information. This technology is crucial for submarines, underwater research, and marine wildlife studies, enabling them to communicate effectively in the challenging underwater environment. Techniques can include simple sonar pings or complex digital modulation methods, depending on the needs of the communication system.
