A new technique dubbed acoustic time reversal could mean that devices such as submarines will get broadband connections while underwater, reports New Scientist.

The new system will improve wireless communications through water by manipulating the unique way that acoustic sounds work under water.

Physicist Geoffrey Edelmann, who works at the US Naval Research Laboratory in Washington DC, spoke to the magazine about the work undertaken by William Kuperman and his colleagues in California.

"Their work is the best. I think they are leading the charge at the moment," said Mr Edelmann.

It was also noted that the group of researchers behind the development will present their findings at the Acoustics 08 meeting, to be held on July 1st in Paris.

Mr Kuperman currently works as a professor of Oceanography at the Scripps Institute, specialising in noise and signal processing - which could help develop further the capabilities of broadband connections at sea.
