Abstract:It is expected that by 2025 wireless communication will be ubiquitous, enabling us to connect all objects surrounding us and supporting emerging applications such as immersive augmented reality. To serve the data and energy requirements of those tiny wireless nodes surrounding us, traditional approaches relying on batteries and power hungry wireless data communication will not suffice. Network densification will inevitably result in multiple wireless service points per room, serving hundreds to thousands of tiny sensors and powerful smart phones with both data and energy.
In this talk, we will start explaining the capabilities of current energy harvesting networks, and analyse the main challenges with respect to achieve far-field wireless power transfer. Next, a novel Massive MIMO based basestation and sensor architecture will be proposed that allows for joint data and power delivery in the downstream. The architecture will be optimized for data and power transfer spectral efficiency, as well as cost by designing the hardware and algorithms for simultaneous wireless data and power transfer. Using channel measurements, the influence of channel hardening on the far-field wireless power transfer efficiency will be studied.
Bio:Sofie Pollin obtained her PhD degree at KU Leuven with honors in 2006. From 2006-2008 she continued her research on wireless communication, energy-efficient networks, cross-layer design, coexistence and cognitive radio at UC Berkeley.In November 2008 she returned to IMEC to become a principal scientist in the green radio team. Currently, she is associate professor at the electrical engineering department at KU Leuven. Her research centers around Networked Systems that require networks that are ever more dense, heterogeneous, battery powered and spectrum constrained. Prof. Pollin is BAEF and Marie Curie fellow, and IEEE senior member.
