Creating and Operating Areas With Reduced Electromagnetic Field Exposure Thanks to Reconfigurable Intelligent Surfaces
Mobile network operators must provide a target quality of service within a
target coverage area. Each generation of networks from the 2nd to the 5th has
reached higher quality-of-service (QoS) targets and coverage area sizes.
However, the deployment of new networks is sometimes challenged by
Electromagnetic Field (EMF) exposure constraints. In this paper, to take into
account these constraints, we assess the novel and recent concept of Reduced
EMF Exposure Area. Such an area would be created and operated by a mobile
network operator upon the request of its customers. In such an area, customers
keep enjoying high data rate internet access while getting a reduced EMF
exposure. To ensure this EMF exposure reduction, we propose to deploy
Reconfigurable Intelligent Surfaces (RIS) connected to the mobile network and
exploit a joint RIS-M-MIMO uplink beamforming scheme. We use our
ray-tracing-based simulation tool to visualize and characterize the Reduced EMF
Exposure Area in a challenging environment in terms of propagation. Our
simulations show that an operator can create and operate such an area under the
condition that it carefully places the RIS in the environment.Comment: Accepted to 2022 23rd IEEE International Workshop on Signal

Smart Wireless Environments Enabled by RISs: Deployment Scenarios and Two Key Challenges
Reconfigurable Intelligent Surfaces (RISs) constitute the enabler for programmable propagation of electromagnetic signals, and are lately being considered as a candidate physicallayer technology for the demanding connectivity, reliability, localization, and sustainability requirements of next generation wireless communications networks. In this paper, we present various deployment scenarios for RIS-enabled smart wireless environments that have been recently designed by the ongoing EU H2020 RISE-6G project. The scenarios are taxonomized according to performance objectives, in particular, connectivity and reliability, localization and sensing, as well as sustainability and secrecy. We identify various deployment strategies and sketch the core architectural requirements in terms of RIS control and signaling, depending on the RIS hardware architectures and their respective capabilities. Furthermore, we introduce and discuss, via preliminary simulation results and reflectarray measurements, two key novel challenges with RIS-enabled smart wireless environments, namely, the area of influence and the bandwidth of influence of RISs, which corroborate the need for careful deployment and planning of this new technology
