GRCon 21 - Multi-Receiver Real-time Physical Intrusion Detection “Burglar Alarm” with GNU Radio ...

Multi-Receiver Real-time Physical Intrusion Detection “Burglar Alarm” with GNU Radio and USRP N310 presented by Daren Swasey, Todd K. Moon, and Mirelle Despain at GNU Radio Conference 2021 Indoor digital communication, such as Wi-Fi, can be used to provide real-time indoor physical intrusion detection, in other words, a “burglar alarm”. In this work, we use signals internal to the radio receiver, such as the PLL or AGC block, to identify when a channel is changing due to a target moving within the physical channel. We describe a test using GNU Radio and Ettus USRP N310 hardware for both a test transmitter and receiver. Test results include a coverage map for a system in a large building. https://events.gnuradio.org/event/8/
