Terms: Acoustic Modem Technology / Acoustic Data Transmissions

By on September 23, 2010

Acoustic modems allow for short-range communication with a submersible data logger by sending data through the water using audible sound. It is ideal for situations in which the data logger is completely submersed underwater, since radio, cellular, and satellite signals often have difficulty propagating through water. This is why submarines utilize sound-based sonar systems instead of radio-dependent radar. Using acoustic transmissions, a nearby ship can periodically retrieve information from a submersed data logger as well as send instructions to the system.
