FROM CONCEPT TO FINISHED PRODUCT
FROM CONCEPT TO FINISHED PRODUCT
We are dedicated to producing top-quality cellular communication devices
from start to finish. To ensure maximum quality and efficiency, we handle most
aspects of the process in-house, from the initial concept to the finished
product, minimizing dependence on external factors.
2G 3G LTE Cat.M NB-IoT

Over the years, we have successfully completed hundreds of customization
projects, ranging from minor firmware adjustments to comprehensive
hardware modifications.
Ourdevicesarebuiltfromthegrounduptoallowformaximumcustomizationwith
minimal effort, easily accommodating new cellular modules, ports, interfaces,
or protocols. Additionally, our routers use OpenWRT, a highly customizable
open-source operating system designed for embedded devices.

MANUFACTURED IN THE HEART OF EUROPE
MANUFACTURED IN THE HEART OF EUROPE
We collaborate with three of Europe’s leading EMS partners, renowned for
their expertise in our field.
These EMS partners utilize state-of-the-art equipment and technology,
adhere to stringent quality control processes, and demonstrate flexibility
and scalability in their operations. They also possess robust supply chain
management capabilities, including reliable sourcing of components, effective
inventory management, and efficient logistics support to ensure the timely
delivery of our products.
By partnering with these industry leaders, we are well-equipped to provide
exceptional IoT solutions to our valued customers.

QUALITY

Our modems facilitate communication between the smart meters
and the utility companies’ back-end systems, providing utilities
with real-time data on energy usage and distribution. This
enables better grid management, reduces outages, and improves
overall grid reliability.
Our products enable secure, real-time communication between
various sensors, devices, and systems, such as smart lighting
systems that can be controlled remotely and respond to changes
in natural light, traffic patterns, and other factors. These benefits
include energy efficiency, cost savings, improved safety and
security, environmental benefits, better quality of life, and
increased control and flexibility.

manufacturers, we have developed modems that are
compatible with a wide range of meters, including those
from Honeywell/Elster, Itron, Landis+Gyr, EHM and Ensor
among others. With our extensive modem portfolio, we can
provide cost-effective and reliable upgrade solutions for
utilities looking to extend the lifespan of their meter fleets.
As mobile operators globally phase out 2G/3G networks in favor of 5G, utilities
relying on these older technologies for their smart meter fleets face a critical
decision. They must weigh the options of either purchasing new, more expensive

Given the substantial cost difference between these two choices, upgrading the modems
often emerges as the more cost-effective and prudent decision for utilities seeking to
extend the lifespan of their smart meter fleets without incurring the expense of replacing
them entirely.
At WM Systems, we are uniquely positioned to help utilities capitalize on these global
retrofit opportunities. Thanks to our past partnerships with some of the largest meter
