  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.
