Experimental Evaluation of Geometry and Reciprocity-Based Beamforming with Large Arrays for RF Wireless Power Transfer
Gilles Callebaut, Jarne Van Mulders
This paper experimentally investigates geometry-based multi-antenna RF wireless power transfer (WPT) using a large-scale distributed indoor transmit array measuring 8 m by 4 m. Geo…
Testbed Evaluation of AI-based Precoding in Distributed MIMO Systems
Tianzheng Miao, Thomas Feys, Gilles Callebaut +3
Distributed MIMO (D-MIMO) has emerged as a key architecture for future sixth-generation (6G) networks, enabling cooperative transmission across spatially distributed access points…
Experimental Study of Interference Suppression for Backscatter Communication in Distributed MIMO
Ahmet Kaplan, Gilles Callebaut, Jarne Van Mulders +1
Bistatic backscatter communication requires strong illumination of a backscatter device (BD), while a spatially separated reader detects the weak modulated reflection. In practice,…
Designing RF-Powered Battery-Less Electronic Shelf Labels With COTS Components
Jarne Van Mulders, Gilles Callebaut
This paper presents a preliminary study exploring the feasibility of designing batteryless electronic shelf labels (ESLs) powered by radio frequency wireless power transfer using c…
GNN-based Precoder Design and Fine-tuning for Cell-free Massive MIMO with Real-world CSI
Tianzheng Miao, Thomas Feys, Gilles Callebaut +4
Cell-free massive MIMO (CF-mMIMO) has emerged as a promising paradigm for delivering uniformly high-quality coverage in future wireless networks. To address the inherent challenges…
Single versus Multi-Tone Wireless Power Transfer with Physically Large Array
Jarne Van Mulders, Benjamin J. B. Deutschmann, Geoffrey Ottoy +4
Distributed beamforming is a key enabler to provide power wirelessly to a massive amount of energy-neutral devices (ENDs). However, without prior information and fully depleted END…
