Retrofit 4G smart meter modems for 2G migration
As telcos are getting prepared for 5G shutting down 2G and 3G networks all around the world, one of the biggest challenges of the IoT world becomes how to migrate the obsolete 2G/GPRS and 3G communication devices to the latest 4G LTE technology? 4G LTE IoT devices are considered future-proof, as LTE-M and NB-IoT devices are expected to work with 5G networks using the non-standalone (NSA) architecture.
Our 4G LTE smart modems provide a future-proof migration path to the higher speed LTE network with the same functionality. We offer our 4G devices with the same outfit, and 2G fallback compatibility for retrofit purposes.
The modem forms part of the AMI (Advanced Metering Infrastructure) of a public utility company. It is suitable for remote meter readout, meter data download, and remote configuration for provider’s schedule or on-demand requests.
Our smart metering modems are fully compatible with the most popular electricity meters (Landis, Itron, Elster/Honeywell, EMH, SAPHIR, PME-PMI), designed to fit under the terminal covers, and addresses all technical requirements of manufacturers
NB-IoT Devices: modems, routers, DCUs, gateways
Narrowband-IoT (and LTE Cat.1, LTE Cat.M, and Cat.M 1) are a fast-growing industrial Low Power Wide-Area Network (LPWAN) technology classified as a 5G technology, and very well suited for applications that require small data transfers over a long period of time. Low amounts of transferred data results in lower operation costs. Some NB-IoT devices are designed to consume significantly less power resulting in a significantly longer battery life (10 years), which alllows for autonomous operation in remote locations with limited access power sources.
4G LTE IoT devices are considered future-proof, as LTE-M and NB-IoT devices are expected to work with 5G networks using the non-standalone (NSA) architecture.
Advantages of NB-IoT:
- Great indoor coverage
- Support for a huge number of connections
- Extended battery life
- Reasonable price
WM Systems has years of experience in developing NB-IoT devices (routers, industrial modems) and smart metering modems). We offer a wide range of M2M product for this cellular network: smart meter modems, routers, transmitters
High-quality IoT and IIoT gateways for industrial applications. These devices are able to manage and control complex connected environments by aggregating and transmitting sensor data, as well as translating communication protocols serving as a bridge between IoT devices and platforms.
Our multi-protocol industrial gateways can be used in many different verticals such as smart grids, building or factory automations, fleet management, security systems, etc., but some are designed for specific applications such as substation management.
There is a growing trend in industrial IoT towards the edge as is the case in many technologies. Our Linux-based routers offer the possibility of fog computing functionalities, as users can develop their own apps to run on them.
Data concentrators (or DCUs) have an important role in a variety of Industrial Internet of Things (IIoT) applications. They collect and aggregate data from multiple industrial devices which can be sent to central management systems.
A data concentrator is the backbone of modern Automated Metering Infrastructures (or AMI) and industrial automation projects. Our multi-protocol data concentrator units (DCU) are capable of collecting data from industrial systems through RS485/ModBus RTU or Modbus TCP/IP as well as from sensors through multiple I/O interfaces. Data transmission can be done by a connected router/modem through wired RS485 connection or wireless mobile network (LTE / Narrow Band). A single DCU + a router/modem can be a very cost-effective solution for monitoring up to 32 industrial devices (electricity/water/gas meters, sensors, etc. ).
Our data concentrators can be connected to all kinds of industrial equipment. We offer customization of our products making it possible for our clients to use them with a combination of IT and OT protocols.

Remote Control Solutions for Public Street Lighting
The option to remotely control public lighting systems is extremely beneficial. Besides providing better lighting service to citizens, it allows operators to optimize maintenance and energy costs.
Our products allow the automated remote control of a public street lighting system by on-demand operation, scheduled switching, or manual control, On/Off power dimming, and sophisticated programming.
We offer products that, when installed inside the existing feeder pillar cabinets, can control street lights by controlling the supplied power to the street light power cable(s). The lights can also be dimmed by lowering the supply voltage. The groups of street lights can be controlled according to reference light sensor(s), by clock and calendar, or manually through a management platform.
Operate the lighting system by remote relay control of the street lamps through the switching cabinet. Configure, manage, and monitor your lamps groups from the head-end (HES) center. Features include monitoring, supervision, and reports.
