IEC/TR 62669:2019（E）是一份技术报告。本文件介绍了一系列根据IEC 62232:2017评估电磁(EM)场的案例研究。本文档中介绍的案例研究涉及有意辐射基站（BS）。BS使用在110MHz至100GHz范围内的一个或多个频率在一个或多个天线上发射，并且RF暴露评估考虑至少在100kHz至300GHz频率范围内的环境源的贡献。选择每个案例研究来说明典型的BS评估场景，并采用IEC 62232:2017中详述的方法。案例研究仅供参考，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吸取的经验教训，提出了关于IEC 62232下一修订版中要考虑的射频评估主题的建议。本文档中描述的方法和途径可用于评估为消费者试用或部署而引入的早期5G产品。本文件提供了应用基于实际最大发射功率或EIRP的合规方法的背景和基本原理。还介绍了收集和分析关于基站发射功率的信息以及基于对操作站点（在网络、子网络或现场试验中）的建模研究或测量研究评估其实际最大射频暴露的指南。关键词:人体暴露、无线通信设备、无线电通信基站附近的射频场强、功率密度和SAR

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.
Keywords: Human Exposure, Wireless Communication Devices, RF field strength, power density and SAR in the vicinity of radiocommunication base stations
