论文摘要
由于电磁场（EMF）的影响无线电站（RBS）对用户产生的电磁场（EMF），有时会质疑5G网络的部署。这项工作的目的是通过将RBS EMF与5G智能手机在商业部署中产生的接触进行比较，从新颖的角度分析此问题。 5G暴露的测量受到了几个实施方面的阻碍，例如4G和5G之间的双重连通性，频谱碎片和载体聚集。为了面对此类问题，我们部署了一个名为5G-EA的新型框架，该框架是针对智能手机和RBS曝光的评估，通过创新的测量算法，能够远程控制可编程的频谱分析仪。在室外和室内地点获得的结果表明，智能手机的曝光（在上行链路流量产生时）在RBS ONE上占主导地位。此外，与非视线的视线相比，视线线的总体暴露量大约减少了一个数量级。此外，与智能手机辐射的总数相比，5G曝光始终代表一小部分（最高38％）。
The deployment of 5G networks is sometimes questioned due to the impact of ElectroMagnetic Field (EMF) generated by Radio Base Station (RBS) on users. The goal of this work is to analyze such issue from a novel perspective, by comparing RBS EMF against exposure generated by 5G smartphones in commercial deployments. The measurement of exposure from 5G is hampered by several implementation aspects, such as dual connectivity between 4G and 5G, spectrum fragmentation, and carrier aggregation. To face such issues, we deploy a novel framework, called 5G-EA, tailored to the assessment of smartphone and RBS exposure through an innovative measurement algorithm, able to remotely control a programmable spectrum analyzer. Results, obtained in both outdoor and indoor locations, reveal that smartphone exposure (upon generation of uplink traffic) dominates over the RBS one. Moreover, Line-of-Sight locations experience a reduction of around one order of magnitude on the overall exposure compared to Non-Line-of-Sight ones. In addition, 5G exposure always represents a small share (up to 38%) compared to the total one radiated by the smartphone.
