QNA demos underwater Dolphin technology
QinetiQ North America (QNA) has successfully demonstrated full-duplex underwater acoustic data communications using its new Dolphin technology, the company announced on 22 August.
The demonstration was part of the Advanced Navy Technology Exercise held in Panama City, Florida, in mid-August.
Dolphin, developed in partnership with Optimal Systems Laboratory, uses cancellation technology that enables simultaneous transmit and receive acoustic communications. This is a key capability in the development of extensive undersea data and communication wireless networks, and a potential problem-solver for navy and commercial customers.
Dolphin technology enables self-forming acoustic underwater networks to operate similarly to wireless land networks with nodes in motion.
Other benefits include frequency independence, allowing Dolphin communications to be configurable on most systems and platforms, such as unmanned underwater vehicles, submarines and ships; and extremely low power communications.
