Harnessing multipath propagation in wireless networks: A meta-surface transformation of wireless networks into smart reconfigurable radio environments

Descripción del proyecto

Transformación de metasuperficies inteligentes de redes inalámbricas

El funcionamiento de las redes de telefonía móvil permanece condicionado por los límites inherentes de los canales inalámbricos. El proyecto Pathfinder, financiado con fondos europeos, intentará impulsar un modelo 2.0 inalámbrico para adaptar canales inalámbricos al funcionamiento de redes de telefonía móvil. Esto les permitirá superar dichos límites inherentes. El proyecto se basará en innovaciones del ámbito de los metamateriales electromagnéticos que pueden controlar y gestionar ondas de radio. Esta tecnología permite el diseño y la producción de metasuperficies inteligentes reconfigurables mediante «software» que optimizan canales inalámbricos y permiten el control de ondas procedentes de dichos canales. El proyecto tiene como objetivo establecer las bases algorítmicas y teóricas de redes 2.0 inalámbricas alimentadas por metasuperficies inteligentes reconfigurables que conducirán a otras transformaciones en redes inalámbricas.


The long-term vision of Pathfinder is to kick-start a wireless 2.0 paradigm where wireless channels will adapt to the operation of cellular networks, allowing networks to overcome the inherent limitations imposed by wireless channels hitherto. In this course, Pathfinder builds upon the advancements in the area of electromagnetic meta-materials that can control and manipulate radio waves. This technology allows for designing and fabricating software reconfigurable intelligent meta-surfaces (RISs) that dynamically optimize the wireless channels in response to the dynamic behavior of radio waves, showing an unprecedented potential to control waves from within the wireless channels.
This control allows for radio waves to circumvent physical obstacles, improving network coverage, while the phase alignment of RIS constituent elements can maximize the power at the receiver through constructive interference. This, can increase data-rates and reduce the transmit power. Furthermore, sensors and IoT devices can “recycle” and backscatter the ambient radio waves through RISs instead of generating their own, realizing the objective of smart, interconnected cities by employing passive elements that neither generate radio waves nor consume power to generate them.

In this setup, the overarching objective of Pathfinder is to set the theoretical and algorithmic foundations of RIS enabled wireless 2.0 networks by deriving: (1) physics-inspired models for the RIS/radio wave interaction. (2) communication & information-theoretic models for RISs networks. (3) models for large-scale analysis of RIS networks. (4) algorithms for the design and optimization of RIS operation. (5) measurements for the experimental verification of the developed models and algorithms. The realization of these objectives can indeed transform wireless networks, driving the economic and intellectual growth of all European society, creating new jobs, increasing revenues and simplifying our lives.
