Industrial networks - Coexistence of wireless systems - Part 2: Coexistence management

IEC 62657-2:2025 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 by supporting to fulfil the requirements using coexistence management.
This edition includes the following significant technical changes with respect to the previous edition:
a) alignment of some definitions and specifications of coexistence parameters in order to facilitate their future inclusion in the IEC Common Data Dictionary (IEC CDD) maintained by the IEC;
b) alignment of some definitions and specifications to be consistent with the new IEC 62657-3 and IEC 62657-4;
c) edition 3 of this document was published in June 2022. Some comments were made in the last development stages of this document asking for explanations on how the parts of the IEC 62657 series were structured and how they were related to each other. Resolution of these comments was deferred until a next edition, which means this edition.
