OMS Generation 5, the open standard for secured IoT networks

As IoT deployments scale across critical infrastructures such as water and energy networks, ensuring trust in data is essential.

Data protection is often associated with cloud security. Yet one critical aspect remains largely overlooked: data production in the device and their collection. This raises a question: how to ensure the integrity of data in the field, before it reaches the database?

The overlooked layer: how data is collected

IoT data is produced in real-world environments, outside controlled IT systems. It depends on embedded devices; communication protocols; and radio technologies.

This “first mile” shapes the integrity and reliability of the data before it even enters the tech stack.  Neglecting this part of the data journey exposes it to a range of security vulnerabilities, such as lack of updates and continuous connectivity. 

Protection starts with standardization: explore OMS Generation 5

The Open Metering System (OMS) is an open, vendor independent standard for meter communication based on the M-Bus European standard. Widely adopted by all the metering industry, the M-Bus protocol connects over 100 million end devices.

In its newest version named OMS Generation 5 (OMS 5), specifications integrate now mioty®4OMS: the smart combination of mioty® robustness and forward and backward compatible OMS standardization.      

Scalability and interoperability: make your networks more secure with OMS 5

 

Designed as a standardized ecosystem across the entire IoT value chain, and now part of the OMS 5 specifications, mioty®4OMS enables:

  • Seamless integration of new meters into existing OMS fixed and mobile network infrastructure,
  • Hybrid smart metering networks combining OMS meters from different vendors,
  • Future-proof and scalable networks thanks to telegram spitting
  • Interoperability with other IoT applications like smart cities

Discover how utilities are already relying on mioty®4OMS.

The telegram splitting mode, now part of OMS specifications

Thanks to mioty’s patented telegram splitting technology, mioty®4OMS offers a higher security level against interference and data losses. The telegram is splitted into small subpackets and transmitted at different times and frequencies. At the gateway, the original message is easily rebuilt. Therefore, if interference occurs, not all subpackets are affected and the telegram integrity can be saved.     

Why it matters: from technical choice to operational risk

The OMS specification provides clear specifications (architecture, protocol, use cases). It ensures transparent governance and long-term availability of technology.

It is a sovereign European open standard, guaranteeing transparent access for all. Indeed, access to patents is governed through structured policies and independent managed licensing pools (Sisvel), avoiding hidden dependencies. It also enables the entire stack to be understood and audited, ensuring trust in the entire data value chain.

For utilities, protection goes far beyond encryption. It is about ensuring that networks remain reliable, scalable, and under control for decades. This is where truly standardized, interoperable technologies designed within open and governed frameworks make the difference.

FAQ

What are the advantages of an open standard for my IoT network?

An open standard ensures standardized data transmission of the sent message and ensures system and devices interoperability, as well as long-term resilience and compatibility.

How can I access the OMS Generation 5 specifications?

The OMS specification is publicly available and can be implemented patent-free by all interested parties. On the OMS-Group e. V.  website, you can download them. Patents are only paid after sales of a device by the device manufacturer.

How can I access to the mioty®4OMS mode?

The annex Q of OMS 5 is dedicated to the LPWAN description. Two modes are explained: "burst mode" and "splitting mode", which both rely on the "physical layer" (PHY). The splitting mode is part of the mioty®4OMS. It is based on the European ETSI standard TS 103 357 and provides clear specifications (architecture, protocol, use cases).
