Industrial networks - Coexistence of wireless systems - Part 2: Coexistence management (IEC 62657-2:2022)
This document:
- specifies the fundamental assumptions, concepts, parameters, and procedures for wireless communication coexistence;
- specifies coexistence parameters and how they are used in an application requiring wireless coexistence;
- provides guidelines, requirements, and best practices for wireless communication's availability and performance in an industrial automation plant; it covers the life-cycle of wireless communication coexistence;
- helps the work of all persons involved with the relevant responsibilities to cope with the critical aspects at each phase of life-cycle of the wireless communication coexistence management in an industrial automation plant. Life-cycle aspects include: planning, design, installation, implementation, operation, maintenance, administration and training;
- provides a common point of reference for wireless communication coexistence for industrial automation sites as a homogeneous guideline to help the users assess and gauge their plant efforts;
- deals with the operational aspects of wireless communication coexistence regarding both the static human/tool-organization and the dynamic network self-organization.
This document provides a major contribution to national and regional regulations. It does not exempt devices from conforming to all requirements of national and regional regulations.

9 FOREWORD
10 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
11 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
12 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
13 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
14 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
15 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
16 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
17 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
18 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
19 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
20 consensus of opinion on the relevant subjects since each technical committee has representation from all
21 interested IEC National Committees.
22 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
23 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
24 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
25 misinterpretation by any end user.
26 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
27 transparently to the maximum extent possible in their national and regional publications. Any divergence between
28 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
29 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
30 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
31 services carried out by independent certification bodies.
32 6) All users should ensure that they have the latest edition of this publication.
33 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
34 members of its technical committees and IEC National Committees for any personal injury, property damage or
35 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
36 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
37 Publications.
38 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
39 indispensable
