Underwater backscatter localization ... the researchers had to dial it down to 100 bits/second in shallow water to obtain a clear signal reflection from the tracker. But a slow bitrate didn ...

because radio waves aren’t really water-friendly. It’s why you commonly see things like sonar employed on submarines, which emit sound waves and measure their reflection off other underwater ...
