IMST | Wireless M-Bus Range Extender (with LoRaWAN®) 404600

The Wireless M-Bus Range Extender is a compact and cost-effective device that collects wireless M-Bus messages from utility meters and forwards them to a LoRaWAN® network.

The Range Extender allows a flexible configuration of calendar events for Wireless M-Bus reception windows as well as device filtering by Manufacturer ID and Device ID to select specific groups of meters. Even large Wireless M-Bus messages with maximum payload size can be forwarded with LoRaWAN® radio packets by means of an integrated segmentation and reassembly protocol.

Description :

The Wireless M-Bus standard (EN 13757-4) is used in many wireless sensor and smart meter applications. These meters and sensors are communicating according to defined radio operation modes based on a standard FSK modulation with more or less range to the corresponding receiving unit.

The LoRa® modulation is a perfect mean to increase the range of wireless communication systems. The Wireless M-Bus Range Extender combines the two existing modulation technics and required communication protocol stacks in one single device.

A typical usecase for this product is the forwarding of WM-Bus messages of a configurable group of sensor / meter devices. This bridge offers a flexible way to define hourly, daily, weekly or monthly reception windows for sampling of WM-Bus messages and a large data memory for temporary buffering. Even large WM-Bus messages with maximum payload size can be forwarded with small LoRaWAN® radio packets by means of an integrated segmentation and reassembly protocol.

Besides LoRaWAN® a proprietary Point-to-Point and Point-to-Multipoint protocol (LR Base) can be selected for local configuration and message forwarding (on request)

 

Use cases:

  1. Smart Meter Data Collection: The Range Extender can collect Wireless M-Bus messages from utility meters, such as electricity, gas, or water meters, and forward them to a LoRaWAN® network. This enables remote and automated smart meter data collection, improving efficiency and accuracy in utility billing.

  2. Wireless Sensor Networks: The device can be used to extend the range of wireless sensor networks based on the Wireless M-Bus standard. It allows sensors in remote or hard-to-reach locations to communicate with central monitoring systems via the LoRaWAN® network.

  3. Smart Grid Integration: The Range Extender facilitates the integration of smart meters and sensors into smart grid infrastructures. It enables real-time data transmission, supporting grid optimization, demand-side management, and load forecasting.
