Monthly Overview: September 2025

September 2025 marked a dynamic month for Information Technology standards, characterized by a blend of foundational infrastructure updates and forward-looking technologies. Among the five standards published, several extended established frameworks (such as LAN/MAN QoS and building automation), while others staked new territory in rapidly developing fields—namely, quantum computing and immersive media. A recurring theme throughout these publications was the drive for interoperability: whether bridging physical and digital environments in buildings, harmonizing quantum hardware with software, or integrating varied multimedia formats for next-generation applications.

This month’s activity is consistent with a broader pattern in IT standardization, where incremental enhancements to established systems are balanced by bold steps into new technological landscapes. The inclusion of both practical control application frameworks (EN ISO 16484-4:2025) and advanced models for quantum computing hardware/software layering (CEN/CLC/TR 18202:2025) indicates the sector’s maturing approach to digital transformation. Professionals across verticals—be it in procurement, engineering, research, or compliance—will find these developments essential for planning, implementation, and future-proofing their IT strategies.

Standards Published This Month

ISO/IEC/IEEE 8802-15-7:2025 – Short-Range Optical Wireless Communications

Information technology – Telecommunications and information exchange between systems – Local and metropolitan area networks – Specific requirements – Part 15-7: Short-range optical wireless communications

This standard delineates the physical layer (PHY) and medium access control (MAC) sublayers for short-range Optical Wireless Communications (OWC) across transparent media. Covering wavelengths from 190 nm up to 10,000 nm, it pushes the envelope for wireless data transmission by leveraging visible, infrared, and ultraviolet light. The specification ensures support for audio and video multimedia services and directly addresses the inherent challenges of OWC—mobility, interference from ambient light, compatibility with both existing light infrastructure and camera-based communications, and compliance with eye safety standards.

OWC will serve as both a supplementary and sometimes alternative infrastructure for high-density data transfer, offering options where radio frequency may be less viable or innovative visible light communications (VLC) are in demand. The architecture’s MAC sublayer is purposely designed for visible links, supporting use cases from building automation to consumer electronics, and even automotive systems.

Key highlights:

• Defines PHY/MAC for light-based communication in the 190–10,000 nm range
• Addresses ambient light interference, mobility, and integration with lighting infrastructure
• Supports multimedia data rates and eye safety compliance for global applications

ISO/IEC/IEEE 8802-1DC:2025 – QoS Provision by Network Systems

Telecommunications and exchange between information technology systems – Requirements for local and metropolitan area networks – Part 1DC: Quality of service provision by network systems

Building on the groundwork of IEEE 802.1Q, this standard brings comprehensive Quality of Service (QoS) principles—such as per-stream filtering, policing, queuing, transmission selection, stream control, and frame preemption—onto network systems that do not function as bridges. In contemporary network environments where deterministic and time-sensitive delivery are increasingly critical (for example, in industrial control or autonomous systems), this specification enhances the reliability of data transfer and supports virtualized networking scenarios.

The standard is especially pertinent for manufacturers and operators managing complex topologies where classic bridging is insufficient or undesirable. It details managed objects and procedures, facilitating compliance in emerging sectors (e.g., automotive Ethernet, industrial IoT) and supporting integration with time-sensitive networking (TSN) architectures.

Key highlights:

• Specifies detailed QoS mechanisms for non-bridge LAN/MAN systems
• Integrates with and expands on IEEE 802.1Q features, including deterministic networking
• Critical for operators in industrial, transport, and converged network sectors

CEN/CLC/TR 18202:2025 – Layer Model of Quantum Computing

Layer model of Quantum Computing

Targeting the universal gate-based quantum computing paradigm, this Technical Report proposes a detailed layer model spanning hardware-specific low-level layers to agnostic, high-level software layers (service, programming, assembly, etc.). The model provides a blueprint for delineating interface and functionality boundaries within quantum systems, with a goal of futureproofing software and hardware development for emerging and diverse quantum architectures—such as transmon, ion trap, and neutral atom systems.

By clearly separating lower hardware stacks from higher-level software abstractions, the TR fosters interoperability across vendors and research groups, supports code portability, and enables co-design dialogues that speed up innovation. The report notably excludes non-universal approaches (like quantum annealing), ensuring its recommendations apply specifically to scalable, circuit-based quantum computers. It is highly relevant for quantum platform developers, researchers, and software providers aiming to unify the toolchain for next-generation quantum applications.

Key highlights:

• Details a full stack layer model for universal gate-based quantum computers
• Encourages standardized interfaces and co-design across hardware and software
• Serves as a foundational reference for cross-platform quantum interoperability

EN ISO 16484-4:2025 – Building Automation and Control: Control Applications

Building automation and control systems (BACS) – Part 4: Control applications (ISO 16484-4:2025)

This European standard specifies functional requirements and application-level control logic for Building Automation and Control Systems (BACS), focusing on lighting, solar protection, and HVAC operations. It provides a comprehensive reference for energy performance optimization, comfort provision, and operational efficiency—translating overall building requirements into actionable control specifications, including interoperability across plant and room-level devices.

The standard supplies templates for functional blocks (such as sensors, actuators, logic modules) and procedures for control strategies ranging from basic heating and cooling management to more advanced integrations like demand-based ventilation and automated shading. It is essential for design engineers, system integrators, facility managers, and energy consultants seeking compliance with both European and international benchmarks for smart buildings.

Key highlights:

• Defines unified control logics for lighting, HVAC, solar protection, and other systems
• Optimizes energy efficiency, comfort, and operational reliability
• Enables integration and interoperability in multi-vendor BACS environments
