Overview
IEC 62657-2:2022 is an international standard developed by the International Electrotechnical Commission (IEC) focusing on the coexistence management of wireless systems in industrial networks. It defines fundamental assumptions, concepts, parameters, and procedures essential for managing wireless communication coexistence within industrial automation environments. This edition emphasizes practical strategies and guidelines to ensure robust wireless communication availability and performance throughout the lifecycle of industrial wireless networks.
This standard serves as a common framework that addresses the complexity of multiple wireless systems operating simultaneously within an industrial plant, mitigating interference and optimizing performance. It is applicable to all stakeholders responsible for wireless coexistence, including plant designers, operators, maintenance teams, and regulatory bodies.
Key Topics
-
Wireless Communication Coexistence: Detailed explanation of coexistence concepts, including manual, automated non-collaborative, and automated collaborative coexistence management mechanisms.
-
Lifecycle Management: Guidance spans all wireless coexistence phases-planning, design, installation, implementation, operation, maintenance, administration, and training to ensure ongoing system resilience.
-
Coexistence Parameters: Specification of technical parameters critical to wireless system performance, such as adjacent channel selectivity, antenna gain, communication availability, frequency usage, power levels, interference types, network topology, and device density.
