The Internet Underwater: Monitoring Undersea Conditions With Acoustic Networks

By Doug

  • TAGS

State University of New York researchers in Buffalo are testing a wireless underwater network of nodes that chirp acoustic, rather than RF, transmissions from lake or ocean floors to a receiver on the water's surface, and then forward that data to the Internet via a cellular connection. The underwater nodes transmit at 11.5 kHz, forming a network that forwards data over the course of potentially many miles, back to a receiving node linked to software...
