tion. The first practical implementation of an underwater wireless system was delayed until 1945, when a single sideband underwater telephone was developed. It is well known that water is a better medium for sound propagation than the air. With a nominal speed of 1500 meters per second, acoustic waves propagate faster in water, when compared to how they propagate 330 meters per second in air. In addition, acoustic waves can travel more than thousands of kilometers in oceans.

"This invention offers a new way to communicate data in underwater channels," said Abdi. "I see it making a major impact on the commercial and naval underwater acoustic communication systems." Potential users include meteorologists monitoring environmental changes in oceans, especially those linked to hurricanes; off-shore oil-drilling companies overseeing underwater work sites; fisheries who make their business from the water; underwater surveillance operators for homeland security and more.
