International Workshop on RIS - Feb, 22&23, 2024 Talk by Dinh-Thuy PHAN HUY (Orange, France)

"Reconfigurable Intelligent Surfaces for 6G: a network operator point of view"
Abstract
To support the continuous growth of the Internet traffic over the last two decades, each new generation of mobile network (3G, 4G, 5G) has been improved with respect to the previous generation, in terms of spectral efficiency, capacity, and energy efficiency. However, from a network operator perspective, each new generation also adds its own cost, in terms of resources such as spectrum, infrastructure deployment and energy consumption, to the costs of all previous deployed generations. Moreover, it adds its own contribution in terms of carbon footprint to the environment and it adds-up to the overall exposure of the Society to Electro-Magnetic Field. Finally, new deployments which do not meet customers or business customers needs, have limited business value. 6G, currently still at the Research stage, has the opportunity to be the first generation to explore disruptive approaches to meet Environment sustainability, Societal sustainability and Economical sustainability. As an example of such disruption, Reconfigurable Intelligent Surface is a new wireless network node which reuses existing waves, is expected to consume less power and can even be made from refurbished material. In this talk, based on our studies and field trials of prototypes with our partners, we analyse the potential of this technology. We elaborate on how it could to meet some business and society needs, whilst reusing existing resources and limiting its impact on the environment. We will also analyse the limitations and challenges ahead, especially in terms of availability of prototypes, trials, spectrum coexistence and integration into standards of wireless networks.
************************
Reconfigurable Intelligent Surfaces are very promising physical-layer candidates for sixth-generation cellular networks.
This international workshop will cover the main scientific and technological questions underlying this promise: electromagnetism, meta-materials, beamforming, adaptive control,network architecture, and network energy expenditure.
