Energy Neutral Devices: Can Hybrid RF Acoustic Signals Point Them Out?
Bert Cox, Chesney Buyle, Liesbet Van der Perre +1
We present a hybrid signaling approach to position energy-neutral devices. Our method combines the best of two worlds: instant RF signals for both communication and energy transfer…
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…
RadioWeaves for efficient connectivity: analysis andimpact of constraints in actual deployments
Liesbet Van der Perre, Erik G. Larsson, Fredrik Tufvesson +3
We present a new type of wireless access infras-tructure consisting of a fabric of dispersed electronic circuitsand antennas that collectively function as a massive, distributed an…
