Stanford researchers recently revealed how a seemingly physics-defying wireless communication technology works. The new technology, called thermal noise communication, harnesses background static that normally is the bane of radio, cellular, and other wireless signals. In a new study published in Proceedings of the National Academy of Sciences, the team showed how a transmitter could deliver data to a receiver without any actively produced signal by manipulating tiny oscillations in voltage. The findings describe how the system works at a fundamental level, opening the door to improving the communication mode and determining real-world applications for it. "We've built a system that others could very easily implement," said senior author Zerina Kapetanovic, an assistant professor of electrical engineering. A physics mysteryIn her previous research at the University of Washington, Kapetanovic studied agricultural sensing technologies, which inspired her to pursue low-power modes of relaying data like soil moisture levels.
