Abstract: First, imagine a tag with the size and the cost of a stamp that broadcasts its message (a simple identity, for instance) without any battery and without propagating any new Radio Frequency (RF) wave: an “Energy-Free Communication” (EFC) tag sending messages thanks to 100%-recycled energy. Then, consider a device (a smartphone, for instance) that detects surrounding tags. Likewise, think of a network that detects tags surrounding devices. Finally, imagine the services that could arise in such environment. Is this just a dream? No! Today (2019), several research labs (including Orange Labs) in the world are designing and prototyping technology enablers for these tags. In this talk, we evaluate the potential opportunities and challenges for the beyond 5G wireless networks to make use of such technical breakthrough. (1) We first explain the so-called “ambient backscattering” principle; a key foundation for EFC. In short, a tag sends a binary message by being transparent to RF waves (when sending “0” bit) or by reflecting RF waves (when sending “1” bit). It is powered by ambient sources of energy (solar, motion, RF, etc.). An RF reader receives the message by detecting changes in the level of received RF power. (2) We then review current global research that has been published on the topic so far. (3) We also present prototypes developed by the SpatialModulation project led by Orange. (4) We then identify potential applications based on such EFC-aware networks and tags, as well as business development perspectives that are likely to give birth to the massive deployment of more sustainable Internet-of-Thing (IoT) services. (5) We finally list the challenges that are raised by this new technology, and that should be investigated in the coming years.

Bio: Dr. Dinh-Thuy PHAN HUY received the degree in engineering from Supelec, in 2001, and the Ph.D. degree in electronics and telecommunications from the National Institute of Applied Sciences of Rennes, France, in 2015. In 2001, she joined France Telecom R&D (now Orange Labs Networks), Châtillon, France. She led the national French collaborative research projects TRIMARAN (2011-2014) and SpatialModulation (2016-2019).
She participated to the following 5G PPP projects: METIS, Fantastic 5G, mmMAGIC and 5GCAR. She holds more than 40 patents and has published more than 20 papers.
She is the recipient of several awards in France: “Prix Impact Economique des Rencontres du Numérique 2016” from the French National Research Agency, “Grand Prix de l’Electronique du General Ferrié 2018” from the French Society of Electricity, Electronics and Information and Communication Technologies and the “Prix Irène Joliot Curie 2018 – category Femme-Recherche-Entreprise” from the French Ministry of Education and Research. Her research interests include wireless communications and beamforming, spatial modulation, predictor antenna, backscattering and intelligent reflecting surfaces.
