A team of researchers at the University of California, San Diego, working with the Defense Advanced Research Projects Agency’s HERMES program, say they may have found an answer to keep the multitude of signals from UAVs to embedded sensors and smart devices of all kinds.
According to DefenseSystems.com, “HERMES, which stands for Hyper-wideband Enabled RF Messaging, was started in 2014 to find way to solve jamming and signal fratricide problems with wideband spread-spectrum communications that provide more than 10 GHz of instantaneous bandwidth and operate below 20 GHz to employ coding gain and spectral filtering, as well as reduce atmospheric absorption. It’s an effort to answer the question of how to keep the signals from all of these devices from interfering with each other.”
“The technology could take advantage of both unlicensed Wi-Fi bands but also large sections of licensed frequencies,” Defense Systems reported.
The researchers published a paper in IEEE’s Journal of Lightwave Technology outlining how the technology could maximize use of the spectrum while providing jam-resistant communications.
