- WiFireNet Detects Concealed Handguns Using Wi-Fi Signals
TechNews reports that the Swedish Defence Research Agency (FOI) developed WiFireNet, an experimental AI system that identifies concealed handguns from changes in Wi-Fi channel state information (CSI). In controlled tests in a small room, the system tracked up to four moving people and achieved 72.5% average accuracy for handgun detection, while accuracy for locating a weapon on a carrier fell to 53.8%. The arXiv preprint also reports unstable performance in unfamiliar room layouts and describes the implementation as a proof of concept using modified IEEE 802.11a equipment; the code, model, and WiFire dataset were open-sourced for further research.
