Long-Range Backscatter: A Bottom-Up Approach
Tijl Schepens, Gilles Callebaut, Liesbet Van der Perre
Continued progress towards energy-neutral Internet of Things (IoT) nodes expose the wireless communication link as the dominant energy bottleneck. While low-power wide-area network…
Weighted-Sum Energy Efficiency Maximization in User-Centric Uplink Cell-Free Massive MIMO
Donghwi Kim, Liesbet Van der Perre, Wan Choi
This paper introduces the weighted-sum energy efficiency (WSEE) as an advanced performance metric designed to represent the uplink energy efficiency (EE) of individual user equipme…
A Parametric Power Model of Upper Mid-Band (FR3) Base Stations for 6G
Emanuele Peschiera, Sangbu Yun, Youngjoo Lee +2
Increasing attention is given to the upper mid-band or Frequency Range 3 (FR3), from 7 to 24 GHz, in the research towards sixth-generation (6G) networks. Promises of offering large…
MmWave for Extended Reality: Open User Mobility Dataset, Characterisation, and Impact on Link Quality
Alexander Marinsek, Sam De Kunst, Gilles Callebaut +2
User mobility in extended reality (XR) can have a major impact on millimeter-wave (mmWave) links and may require dedicated mitigation strategies to ensure reliable connections and…
How to Perform Distributed Precoding to Wirelessly Power Shelf Labels: Signal Processing and Measurements
Gilles Callebaut, Jarne Van Mulders, Bert Cox +3
Wireless power transfer (WPT) has garnered increasing attention due to its potential to eliminate device-side batteries. With the advent of (distributed) multiple-input multiple-ou…
IoT on the Road to Sustainability: Vehicle or Bandit?
Jona Cappelle, Liesbet Van der Perre, Emma Fitzgerald +5
The Internet of Things (IoT) can support the evolution towards a digital and green future. However, the introduction of the technology clearly has in itself a direct adverse ecolog…
