Understanding the Need for Aquatools in Underwater

Communication

Underwater acoustic communication diﬀers signiﬁcantly from terrestrial wireless

communication due to the unique physical properties of the aquatic environment. Signals

travel slower underwater, experience high attenuation, multipath eﬀects, and are heavily

inﬂuenced by environmental factors such as salinity, temperature, and pressure. These

challenges make designing and testing underwater networks a complex task.
