New system allows near-zero-power sensors to communicate data over long distances
Could make low-cost remote medical monitoring and the "internet of things" practical
September 18, 2017
University of Washington (UW) researchers have developed a low-cost, long-range data-communication system that could make it possible for medical sensors or billions of low-cost “internet of things” objects to connect via radio signals at long distances (up to 2.8 kilometers) and with 1000 times lower required power (9.25 microwatts in an experiment) compared to existing technologies.
“People have been talking about embedding connectivity into everyday objects … for… read more
