Indoor Localization of Smartphones Thanks to Zero-Energy-Devices Beacons
We accurately simulate the ambient waves from a BS of Orange 4G commercial network, inside an existing large building covered with ZED beacons, thanks to a ray-tracing-based propagation simulation tool.
Zero-energy Devices for 6G: Technical Enablers at a Glance
Low-cost, resource-constrained, maintenance-free, and energy-harvesting (EH) Internet of Things (IoT) devices, referred to as zero-energy devices (ZEDs), are rapidly attracting attention from industry and academia due to their myriad of applications.
A Novel RIS-Aided EMF-Aware Beamforming Using Directional Spreading, Truncation and Boosting
In some propagation conditions, when the base station serves the same target user equipment for a long period, it reduces the transmit power (and degrades the received power) to avoid creating high exposure regions located in the vicinity of the antenna and concentrated in few directions (corresponding to the best propagation paths between the antenna and the receiver).
Creating and Operating Areas With Reduced Electromagnetic Field Exposure Thanks to Reconfigurable Intelligent Surfaces
In this paper, to take into account these constraints, we assess the novel and recent concept of Reduced EMF Exposure Area.
A Novel RIS-Aided EMF Exposure Aware Approach using an Angularly Equalized Virtual Propagation Channel
However, in some cases, where the BS serves the same user for a long period, and in some propagation conditions, such systems reduce their transmit power to avoid creating unwanted regions of electromagnetic field exposure exceeding the regulatory threshold, beyond the circle around the BS that limits the distance between people and the BS antenna.
Polarization-Based Reconfigurable Tags for Robust Ambient Backscatter Communications
In this paper, we propose a polarization-based reconfigurable antenna in order to improve the robustness of the tag-to-reader link against the source-to-reader direct interference.
First experimental evaluation of ambient backscatter communications with massive MIMO reader
A mobile device transmits a signal that is backscattered by a tag and received by the reader.
Robust Ambient Backscatter Communications with Polarization Reconfigurable Tags
In this paper, for the first time, we propose to exploit a "polarization reconfigurable" antenna to improve robustness of the tag-to-reader link against the source-to-reader direct interference.
Reconfigurable Intelligent Surface -Assisted Ambient Backscatter Communications -- Experimental Assessment
On the other hand, in an ambient backscatter system, a device, named tag, communicates towards a reader by backscattering the waves of an ambient source (such as a TV tower).
Predictor Antenna: A Technique to Boost the Performance of Moving Relays
In future wireless systems, a large number of users may access the networks via moving relays (MRs) installed on top of vehicles.
