High-frequency underwater acoustic communication development system

Underwater acoustic links have low capacity because that operate at low frequencies. These low frequencies are used because they allow long range communication. Networks allow short range links to provide long range communication, eliminating the need for these long link ranges. Therefore high frequencies can be used for underwater acoustic communication. Such high-frequency underwater acoustic communication systems have not been widely studied or developed before. Specialist hardware is required to support such development. This paper explains the development of such specialist hardware.
