论文摘要
移动网络运营商必须在目标覆盖区域内提供目标服务质量。从第二到第五的每一代网络都达到了更高的服务质量（QoS）目标和覆盖面积大小。但是，有时会受到电磁场（EMF）暴露限制的挑战。在本文中，考虑到这些约束，我们评估了EMF暴露区域减少的新颖概念。移动网络运营商应其客户的要求创建和操作此类区域。在这样的领域，客户继续享受高数据速率互联网访问，同时减少EMF的曝光率。为了确保减少EMF暴露，我们建议部署连接到移动网络的可重新配置智能表面（RIS），并利用联合RIS-MIMO-MIMO上行链路上链接面向方案。我们使用基于射线追踪的仿真工具可视化和表征在传播方面充满挑战的环境中减少的EMF暴露区域。我们的模拟表明，操作员可以在仔细地将RIS放置在环境中的条件下创建和操作这样的区域。
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.
