REFERENCES

Our industrial networking devices cut through marketing noise by delivering measurable results. We’ve secured high-profile tenders with global industry leaders not through flashy presentations, but through engineering that solves real-world problems.

To date, we have successfully sold over 1 million IoT devices across more than 40+ countries on four continents, serving more than 100 major companies, primarily utilities. However, we prioritize customer confidentiality, as it is a standard practice in industries where cybersecurity is a critical concern.

Our products are important component in  mission-critical infrastructures. We’re not just selling devices; we’re enabling smart grids, public street lighting, advanced metering for electricity, water, and gas networks, and precision security monitoring.

 

PARTNERS

In many large projects, we work with high-profile partners: system integrators, mobile operators, cellular module manufacturers, mobile infrastructure providers, meter manufacturers, etc. These partnerships are extremely important for us, and we strive to maintain strong, long-term relationships based on trust, innovation, and mutual success. By collaborating closely with industry leaders, we ensure that we stay at the forefront of technological advancements and are able to participate in major projects, delivering the most reliable and cutting-edge solutions to our clients. These collaborations help us meet the diverse needs of our customers and drive the success of the projects we work on.

At our company, we take the security and confidentiality of our customers very seriously. As a provider of critical components, such as communications infrastructure for highly sensitive applications like smart grids and utilities, we understand the potential risks that come with disclosing specific project details or customer names. Sharing this information could inadvertently expose vulnerabilities, as cyber threats are constantly evolving. For instance, if malicious actors were to know the specific modem or router used by a utility in its smart grid, they could tailor their attacks to target the system more effectively, potentially compromising its overall security. Therefore, we maintain a strict policy of not sharing customer names or project specifics, ensuring that our solutions remain secure and our customers’ infrastructures protected from potential threats.

“Connectivity without proper security is just a threat.”

Mr. Bela Kormos, CEO of WM Systems

SUSTAINABILITY

Sustainability isn’t about buzzwords—it’s about intelligent engineering and responsible design. At WM Systems, we view sustainability as a technical challenge and a business opportunity. Our cellular communication devices are engineered to maximize longevity, minimize environmental impact, and deliver real-world efficiency.

We focus on three core principles:

  1. Extended Product Lifecycle: Our devices are built to last, with modular designs that allow for component upgrades instead of complete replacements. This means less electronic waste and lower total cost of ownership for our customers.
  2. Energy Efficiency: Every milliwatt matters. We optimize our hardware and firmware to reduce power consumption, extending device battery life and reducing the overall energy footprint of our IoT products.
  3. Responsible Manufacturing: We select suppliers who meet strict environmental and ethical standards. Our supply chain isn’t about checking boxes — it’s about ensuring that every component is sourced and produced with measurable environmental considerations.

Sustainability for us isn’t a marketing strategy. It’s engineering intelligence applied to real-world resource management.

Supply Chain & Logistics

Our engineering approach to supply chain management is ruthlessly pragmatic. We’ve established a robust network of Electronics Manufacturing Services (EMS) partners, carefully selected for their precision and reliability. Our contracts with component suppliers, from circuit board manufacturers to antenna and enclosure specialists, aren’t just agreements — they’re strategic engineering partnerships.

We don’t just track inventory; we anticipate it. Our rolling production planning allows us to forecast component requirements up to a year in advance. Critical components with long lead times are strategically stockpiled, eliminating potential production bottlenecks.

 

Production Quality

Our commitment to quality, security, and employee safety is demonstrated through our adherence to internationally recognized standards. We hold the following ISO certifications:

  • ISO 9001: Ensuring consistent quality management across all stages of our production processes, enabling us to meet customer requirements and continuously improve our operations.
  • ISO 27001: Reinforcing our dedication to data security by implementing robust information security management systems that protect both our own and our customers’ sensitive data.

 

“You cannot be serious about developing secure IoT devices without ISO 27001.”

Mr. Bela Kormos, CEO of WM Systems

 

  • ISO 45001: Reflecting our commitment to maintaining a safe and healthy working environment, with effective risk management and continuous improvements in workplace safety.

 

These certifications are a testament to our ongoing efforts to deliver high-quality products while prioritizing the security of our solutions and the wellbeing of our team.

Manufacturing is where engineering meets execution. Our ODM partners deploy state-of-the-art surface mount technology across three inline SMT production lines, utilizing cutting-edge soldering and implantation machinery. This isn’t about impressive equipment—it’s about consistent, measurable precision.

Quality control isn’t a checkbox—it’s a systematic process. We implement rigorous Incoming Quality Control (IQC) for all incoming materials. Every component is meticulously inspected and documented. Our vendor monitoring process ensures that only components meeting our exacting standards enter production.

Our capabilities span the entire product lifecycle:

  • Full procurement services
  • Plastics and metal fabrication
  • Custom packaging
  • Advanced testing (AOI, ICT, functional)
  • Component tracking

Our product failure rate speaks for itself: consistently under 0.1%.

 

Testing

We don’t just test products — we stress-test them. Our comprehensive testing regime includes:

  • Climate chamber tests (heat, cold, vibration)
  • Accelerated aging simulations
  • Extensive cellular connectivity stability tests

Independent, accredited laboratories validate our products, securing CE and Radio Equipment Directive (ReD) certifications. Our proprietary End-of-Line (EoL) testing system ensures 100% product verification in a controlled, isolated environment.

Every device undergoes comprehensive functionality testing and firmware configuration. No exceptions, no compromises.

This isn’t just quality control. It’s engineering discipline.
