IEC 62657-4:2025

Overview

IEC 62657-4:2025 - "Industrial networks - Coexistence of wireless systems - Part 4: Coexistence management with central coordination of wireless applications" specifies a concept and methods for central coordination (CC) of automation applications that use wireless communications. It extends coexistence management defined in IEC 62657-2 and uses the formal description approach in IEC 62657-3. The standard defines system elements, interfaces, data, functions and message formats for a Central Coordination Point (CCP) approach to automated coexistence management. It is technology- and frequency-agnostic.

Key topics and requirements

• Central coordination architecture: definition of the CCP, coordination database and supporting system elements for managing coexistence of wireless applications.
• Parameters for coexistence assessment and control: application and radio parameters used to determine and maintain the coexistence state.
• Management & control services: subscription, configuration, control, resource management and database access services required for CCP-managed systems.
• Message formats and service sequences: defined sequences and standardized message formats to ensure interoperability between CCP providers and device/system providers.
• Automated coexistence procedures: requirements for automated processes to determine coexistence state, trigger control actions and apply amendments to wireless communication systems.
• Interoperability focus: standardized data items (parameters), hierarchical data structures and unified execution sequences for CCP ↔ device/system exchanges.
• Spectrum sensing and incumbent protection: interfaces and data exchange for spectrum sensing components and protection of incumbent radio systems.
• Not technology-limited: applicable across radio frequency ranges and wireless technologies.

Practical applications and users

Who uses IEC 62657-4:2025:

• System integrators and plant automation engineers designing industrial wireless deployments that must coexist with other wireless systems.
• Device and wireless system manufacturers implementing CCP interfaces and standardized message formats to ensure interoperability.
• CCP providers and solution vendors creating central coordination platforms for multi-vendor environments.
• Network operators, facility managers and safety-critical plant operators needing automated coexistence management and protection of incumbent services.
• Regulatory bodies and test laboratories assessing coexistence compliance.

Practical uses:

• Designing and implementing a central coordination point to manage spectrum use, power, channels and medium access across devices.
• Developing automated coexistence workflows to coordinate legacy and new wireless systems.
• Enabling multi-vendor interoperability by implementing the defined data items, message formats and service sequences.
• Integrating spectrum sensing and coordination databases to protect incumbents and optimize medium resource allocation.
