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…
Massive MIMO goes Sub-GHz: Implementation and Experimental Exploration for LPWANs
Gilles Callebaut, Sara Gunnarsson, Andrea P. Guevara +4
Low-Power Wide-Area Networks operating in the unlicensed bands are being deployed to connect a rapidly growing number of Internet-of-Things devices. While the unlicensed sub-GHz ba…
A Light Signalling Approach to Node Grouping for Massive MIMO IoT Networks
Emma Fitzgerald, Michał Pióro, Harsh Tataria +3
Massive MIMO is a leading technology to connect very large numbers of energy constrained nodes, as it offers both extensive spatial multiplexing and large array gain. A challenge r…
Channel Hardening in Massive MIMO: Model Parameters and Experimental Assessment
Sara Gunnarsson, José Flordelis, Liesbet Van der Perre +1
Reliability is becoming increasingly important for many applications envisioned for future wireless systems. A technology that could improve reliability in these systems is massive…
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…
