Full title and description

IEC TR 62669:2019 — 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. This Technical Report provides worked case studies that apply the methods of IEC 62232 (product compliance, product installation compliance and in‑situ assessments) to a variety of base‑station (BS) scenarios; the examples cover single and multiple antennas, multiple frequencies and include guidance on accounting for ambient sources and on practical measurement and modelling approaches.

Abstract

IEC/TR 62669:2019 (2nd edition) presents a series of illustrative case studies in which electromagnetic fields from intentionally radiating base stations are evaluated using the methods of IEC 62232. Case studies span frequency components used in modern cellular deployments (110 MHz to 100 GHz) and take into account ambient contributions across a wider range (at least 100 kHz to 300 GHz). The report is informative: it explains practical choices for modelling and measurements, discusses how to collect and analyse transmitted power/EIRP data, proposes lessons for future revisions of IEC 62232, and highlights applicability to early 5G deployments and field trials.

Scope

This Technical Report provides practical case studies that illustrate application of IEC 62232 methods for evaluating RF field strength, power density and specific absorption rate (SAR) in the vicinity of radiocommunication base stations. The case studies cover intentionally radiating base stations using one or more antennas and operating over frequencies typically considered by IEC 62232 (nominally 110 MHz to 100 GHz in this report), and include consideration of ambient sources over a broader band (at least 100 kHz to 300 GHz). The document supplies guidance on modelling vs measurement approaches, how to determine and use actual maximum transmitted power or EIRP for compliance assessments, and lessons learned that inform future revisions of IEC 62232.

Key topics and requirements

• Worked case studies applying IEC 62232 evaluation methods to representative base‑station scenarios (single/multi‑antenna, multi‑band deployments).
• Frequency applicability and ambient‑source considerations (case work uses 110 MHz to 100 GHz; ambient sources are considered to at least 100 kHz–300 GHz).
• Guidance on collecting and analysing transmitted power and EIRP data for realistic compliance assessments.
• Recommendations on measurement and modelling approaches for on‑site and network/sub‑network assessments (including uncertainty considerations).
• Practical notes for early 5G product trials and deployments and suggestions for topics to consider in future revisions of IEC 62232.

These topics are informative (case‑study based) rather than normative requirements; the report is intended to support correct application of IEC 62232.

Typical use and users

Primary users are RF safety assessors, wireless product and base‑station manufacturers, test laboratories, mobile network operators, installation engineers and national regulators. The report is used as practical guidance to complement the normative methods in IEC 62232 when preparing compliance boundary information, conducting installation/site assessments and performing in‑service exposure evaluations (including field trials of new technologies).

Related standards

The report directly supports and is intended to be used with IEC 62232 (determination of RF field strength, power density and SAR in the vicinity of base stations). It is commonly used alongside exposure‑limit guidance and measurement standards referenced in IEC 62232 (for example ICNIRP guidelines and IEEE C95.1 family references cited in IEC 62232 bibliographies). Users often consult related IEC and regional standards for measurement technique and reporting norms when performing practical assessments.

FAQ

Q: What is this standard?

A: IEC TR 62669:2019 is a Technical Report of the IEC that provides a collection of case studies illustrating application of IEC 62232 methods to evaluate RF field strength, power density and SAR around radiocommunication base stations.

Q: What does it cover?

A: It covers practical examples applying IEC 62232: case descriptions, modelling and measurement approaches, how to handle transmitted power/EIRP data, treatment of ambient sources and recommendations drawn from the analysed cases; frequencies illustrated in the report span roughly 110 MHz to 100 GHz, with ambient considerations across a wider band.

Q: Who typically uses it?

A: RF safety engineers, network operators, manufacturers of base‑station equipment, test laboratories, installation engineers and regulators — essentially anyone performing compliance boundary calculations, installation/site assessments or in‑service exposure evaluations for base stations.

Q: Is it current or superseded?

A: IEC TR 62669:2019 is the second edition (published 5 April 2019) and supersedes IEC TR 62669:2011. As a Technical Report it provides informative guidance; users should also consult the latest edition of IEC 62232 and relevant national/regional exposure limits when performing assessments.

Q: Is it part of a series?

A: It is an IEC Technical Report that specifically supports the IEC 62232 series of documents (the normative standard for RF exposure evaluation around base stations). It sits in the suite of IEC/TC 106 publications concerned with methods for assessing human exposure to electric, magnetic and electromagnetic fields.

Q: What are the key keywords?

A: RF exposure; base station case studies; power density; field strength; SAR; EIRP; measurement and modelling; IEC 62232; human exposure; 5G deployments.
