Robust Ambient Backscatter Communications with Polarization Reconfigurable Tags

no code implementations2 Nov 2021 Romain Fara, Dinh-Thuy Phan-Huy, Abdelwaheb Ourir, Marco Di Renzo, Julien de Rosny

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.

Polarization-Based Reconfigurable Tags for Robust Ambient Backscatter Communications

no code implementations2 Nov 2021 Romain Fara, Dinh-Thuy Phan-Huy, Abdelwaheb Ourir, Yvan Kokar, Jean-Christophe Prévotet, Maryline Hélard, Marco Di Renzo, Julien de Rosny

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.

A Prototype of Reconfigurable Intelligent Surface with Continuous Control of the Reflection Phase

no code implementations25 May 2021 Romain Fara, Philippe Ratajczak, Dinh-Thuy Phan Huy, Abdelwaheb Ourir, Marco Di Renzo, Julien de Rosny

On the other hand, ambient backscatter communications (AmBC) is another promising technology that is tailored for addressing the energy efficiency requirements for the Internet of Things (IoT).

Reconfigurable Intelligent Surface -Assisted Ambient Backscatter Communications -- Experimental Assessment

no code implementations15 Mar 2021 Romain Fara, Dinh-Thuy Phan-Huy, Philippe Ratajczak, Abdelwaheb Ourir, Marco Di Renzo, Julien de Rosny

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).
