This document, which is a Technical Report, 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.dition 2.0 2019-04 TECHNICAL REPORT colour inside Case studies supporting IEC 62232 – Determination of RF field strength, power density and SAR in the vicinity of radiocommunication base stations for the purpose of evaluating human exposure IEC TR 62669:2019-04(en) THIS PUBLICATION IS COPYRIGHT PROTECTED Copyright ？ 2019 IEC, Geneva, Switzerland All rights reserved.
