1. Introduction

Wireless M-Bus (wM-Bus) is a widely used protocol for smart metering applications, enabling efficient data transmission from utility meters to data collection systems. However, in large industrial sites, urban environments, or buildings with thick walls, signal coverage can become a challenge. To address this, the STG Series by REDZ offers a repeater function that significantly extends the range of Wireless M-Bus devices, ensuring reliable data transmission without additional infrastructure.

2. Why Extend the Wireless M-Bus Range?

1. Overcoming Signal Obstacles – Buildings with thick walls, basements, or underground installations can weaken the signal.

2. Covering Large Areas – Industrial sites, smart cities, and large residential complexes require extended range.

3. Improving Data Reliability – Weak signals lead to data loss, increasing transmission retries and power consumption.

4. Reducing Infrastructure Costs – Instead of deploying additional gateways, a repeater enhances network coverage efficiently.

3. How the STG Series Repeater Function Works

The STG Series devices from REDZ feature an integrated Wireless M-Bus Repeater Mode, designed to extend the range of smart meters and other wireless devices. Here’s how it works:

1. Signal Reception – The STG device listens for incoming wM-Bus messages from remote meters.

2. Packet Processing – It buffers and processes the received packets while ensuring minimal latency.

3. Rebroadcasting – The repeater retransmits the data towards the main data collection point (e.g., an MQTT server, gateway, or head-end system).

The STG Series supports multiple Wireless M-Bus modes, including S, T, C, and R modes, ensuring compatibility with different smart metering setups.

4. Benefits of Using STG Series Repeaters

✔ Extended Range – Improves coverage in hard-to-reach locations.

✔ Reliable Communication – Reduces packet loss and improves data accuracy.

✔ Low Power Consumption – Optimized for energy-efficient, long-term operation.

✔ Easy Deployment – Simple plug-and-play setup with configurable parameters.

✔ Cost-Effective – Eliminates the need for additional gateways or repeaters.

5. Use Cases

• Smart Metering in Residential and Commercial Buildings

• Industrial Facilities with Wireless Monitoring

• Smart Cities and IoT Deployments

• Water, Gas, and Electricity Metering Networks

6. Conclusion

Extending the range of Wireless M-Bus devices is crucial for ensuring uninterrupted data transmission in large or complex environments. The STG Series by REDZ provides an efficient Repeater Function, offering a cost-effective, reliable, and easy-to-deploy solution for smart metering and IoT applications.
