Submarine data exchange methods
The article discusses data exchange techniques between submarines underwater, away from internet networks. It explains that water absorbs radio waves, making internet communication in deep waters difficult. Acoustic waves are used to transmit data, but at limited speeds, and their effectiveness is influenced by marine noise, temperature, and depth. Some military submarines rely on low-frequency radio waves, but these are not suitable for transmitting large amounts of data. Such systems require antennas near the surface or communication buoys to pass information via satellites, with security and operational restrictions. Recent research includes optical and laser communication technologies for faster data transfer over shorter distances, alongside the development of networks that combine sound, radio, and relay stations. Underwater communication systems depend on multiple technologies according to depth, distance, and data volume to ensure security and efficiency.
