Underwater Communications Application:
Acoustic communication systems are intrinsically reliable, extremely sensitive, inherently rugged, and are competitively priced. Representing a vital technology, underwater acoustic communication is extensively employed for transmitting and receiving signals under water. While there are several commissioning methods for underwater acoustic communication, hydrophones are the most popular approach. Underwater communication involves various challenges like channel time variations, minimal present bandwidth, multi-path propagation and long-range signal attenuation, which can be mitigated using acoustic communication. Over the years underwater wireless communication has emerged to be important for marine military and commercial activities. Underwater communication networks (UWCN) are rapidly growing to service submarine operations, coastal surveillance systems, monitor autonomous oil-rigs, conduct ocean research & underwater exploration etc. Acoustic transmission ranks primary among the technologies deployed given the ability of sound to travel far in water.
