The underwater acoustic modem encodes text, voice, and image data into digital signals and converts them into acoustic signals. These signals propagate through water to the receiving transducer, where they are converted back into electrical signals. After decoding, the original information—such as sound, text, and images—is restored.
1.Stable data communication with high robustness.
2.Long communication range.
3.Selectable communication modes.
4.The sleep mode has low power consumption and can be quickly awakened.
1.Real-time underwater communication for platforms such as AUVs, ROVs, manned submersibles, and moored buoys.
2.Construction of subsea communication networks.
1.AUVs, ROVs, USVs, and wave gliders.
2.Moored buoys and drifting buoys.
3.Manned submersibles or sightseeing submarines.
4.Various underwater platforms.
