'JANUS' - Underwater Robots Could Learn a New Language

Satellites and mobile phones, built on international standards, help keep the world connected. But the communications technology used on land does not work well underwater. Researchers from the NATO Science and Technology Organization's Center for Maritime Research and Experimentation  have now developed a standard for underwater acoustic communications called JANUS, opening up many underwater communication applications. The researchers are working to support effective underwater communication networks to allow undersea robots to work together, autonomously. If needed, the operation can be managed by land-based engineers who monitor all the communications from a command and control room ashore. The connection to land is made through gateway buoys on the surface of the water equipped with radio links to local support platforms or satellites.
