High Precision Hybrid RF and Ultrasonic Chirp-based Ranging for Low-Power IoT Nodes
Bert Cox, Liesbet Van der Perre, Stijn Wielandt +2
Hybrid acoustic-RF systems offer excellent ranging accuracy, yet they typically come at a power consumption that is too high to meet the energy constraints of mobile IoT nodes. We…
