IEC 62657-4:2022

Overview

IEC 62657-4:2022 is an international standard published by the International Electrotechnical Commission (IEC) that focuses on the coexistence management of wireless systems within industrial networks. Specifically, this part (Part 4) addresses the concept and methods for central coordination (CC) of wireless automation applications. It extends coexistence management principles from IEC 62657-2 by specifying system elements, interfaces, and procedures for a central coordination point (CCP) approach to managing wireless coexistence.

The standard is applicable to all wireless communication technologies and frequency ranges, providing automated coexistence management system requirements. It defines the framework for assessing coexistence states and implementing automated procedures to maintain optimal wireless communication performance in complex industrial environments.

Key Topics

• Central Coordination Concept Establishes a central coordination point (CCP) that manages wireless applications, enabling seamless coexistence between legacy and new wireless systems.

• Coexistence State Assessment Defines parameters and data exchange rules required to determine the current coexistence state, ensuring reliable spectrum utilisation.

• Automated Coexistence Procedures Specifies methods for automated management and amendment of coexistence strategies, minimizing manual interventions in industrial wireless networks.

• System Architecture and Interfaces Describes system elements including wireless devices, CCP, coordination databases, and spectrum sensing systems as well as protocol reference models for control and management.

• Wireless Communication Application Management Details services for managing communication requirements, subscribing/unsubscribing devices or systems, device configuration, and medium resource management.

• Coexistence with Incumbent Systems Illustrates protection schemes for incumbent radio systems sharing frequency bands with wireless automation applications.

Applications

IEC 62657-4:2022 serves as a vital reference for:

• Industrial Automation Networks Facilitating coordinated wireless device communication in factories, plants, and process automation scenarios to mitigate interference issues.

• Wireless System Developers Guiding the design and implementation of wireless coexistence management features in new wireless technologies and devices.

• Network Operators and Integrators Offering standardized procedures to deploy coexistence management frameworks that maintain system reliability and optimize spectral efficiency.

• Regulatory Compliance and Spectrum Management Providing mechanisms to comply with radio frequency regulations while efficiently using shared industrial wireless frequency bands.

By using the CCP approach outlined in this standard, industrial stakeholders can achieve enhanced wireless network stability, coexistence harmony, and reduced communication failures in multi-system environments.
