支持IEC 62232的案例研究——为评估人体暴露而测定无线电通信基站附近的射频场强、功率密度和SAR

[中文适用范围]： 本文档是一份技术报告，介绍了一系列案例研究，在这些案例研究中，电磁场是根据IEC 62232:2017进行评价的。本文档中介绍的案例研究涉及故意辐射的基站（BS）。基站使用一个或多个天线在一个或多个频率（范围从110 MHz到100 GHz）进行传输，射频曝光评估考虑了来自环境源（至少涵盖100 kHz到300 GHz频率范围）的贡献。每个案例研究都选择来说明典型的基站评估场景，并采用IEC 62232:2017中详述的方法。提供的案例研究仅供指导，不能替代对IEC 62232:2017要求的透彻理解。基于从每个案例研究中汲取的经验教训，提出了关于在IEC 62232的下次修订中应考虑的主题的建议。本文档描述的方法和方法对于评估引入用于消费者试验或部署的早期5G产品很有用。本文档提供了基于实际最大传输功率或等效全向辐射功率（EIRP）的应用合规性方法的背景和基本原理。还介绍了收集和分析有关基站传输功率的信息、并通过模型研究或在运营站点（在网络、子网络或现场试验中）进行的测量研究来评估其实际最大射频曝光的指南。 [外文原描述]： IEC/TR 62669:2019(E) is a Technical Report. This document presents a series of case studies in which electromagnetic (EM) fields are evaluated in accordance with IEC 62232:2017. The case studies presented in this document involve intentionally radiating base stations (BS). The BS transmit on one or more antennas using one or more frequencies in the range 110 MHz to 100 GHz and RF exposure assessments take into account the contribution of ambient sources at least in the 100 kHz to 300 GHz frequency range. Each case study has been chosen to illustrate a typical BS evaluation scenario and employs the methods detailed in IEC 62232:2017. The case studies are provided for guidance only and are not a substitute for a thorough understanding of the requirements of IEC 62232:2017. Based on the lessons learned from each case study, recommendations about RF assessment topics to be considered in the next revision of IEC 62232 are proposed. The methodologies and approaches described in this document are useful for the assessment of early 5G products introduced for consumer trials or deployments. This document provides background and rationale for applying a compliance approach based on the actual maximum transmitted power or EIRP. Guidance for collecting and analysing information about the transmitted power of a base station and evaluating its actual maximum RF exposure based on modelling studies or measurement studies on operational sites (in networks, sub-networks or field trials) is also presented. This second edition cancels and replaces the first edition published in 2011. This edition constitutes a technical revision. Keywords: Human Exposure, Wireless Communication Devices, RF field strength, power density and SAR in the vicinity of radiocommunication base stations
