FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international

co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and

in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,

Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their

preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with

may participate in this preparatory work. International, governmental and non-governmental organizations liaising

with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for

Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence between

any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent

rights. IEC shall not be held responsible for identifying any or all such patent rights.

IEC 62657-3 has been prepared by subcommittee 65C: Industrial communication networks, of

IEC technical committee 65: Industrial-process measurement, control and automation. It is an

International Standard.
The text of this International Standard is based on the following documents:

The intended audience for the IEC 62657 series is shown in Table 1.

This document is aimed at plant owners that are operating industrial wireless solutions,

manufacturers of industrial wireless devices, as well as wireless system integrators and

operators.

Plant owners need to understand the nature of the coexistence state with respect to wireless

automation systems. Also, they need to make sure that all impacts to the industrial wireless

application systems represented by parameters are taken into account. This document provides

them the information needed to understand coexistence management parameters and each

relationship for a reliable plant operation.

Device manufacturers should provide quantitative parameters on their wireless device and

system to manage the coexistence of the wireless industrial application based on IEC 62657-2.

This document defines related parameters and interfaces of devices for automatic coexistence

management.

System integrators should, in collaboration with the plant owner and device manufacturers,

design, implement, and manage the wireless industrial automation systems throughout the plant

lifecycle. This document provides essential parameters and interfaces for coexistence

management for system integrators.

A consideration of this document is to outline the features of automated collaborative

coexistence management to develop solutions with, for example, a central coordination point

(CCP), with a software-defined networking approach for flexible use of frequency spectrum or

using a global navigation satellite system (GNSS) for location-based use of frequency spectrum.

Figure 1 shows the relation between the parts of the IEC 62657 series.
