2G/GPRS cellular M-Bus gateway
NVS Gateway 2G
The same job as the 4G model at a lower installed cost. It reads the M-Bus line and sends the data to the panel over the mobile network. Chosen when extending an existing 2G fleet, or where budget decides the specification.

What it does
Lower installed cost
Cost per device is below the 4G model, which noticeably lowers the total on multi-block projects.
Fits an existing fleet
If you already run 2G devices, installation and maintenance habits carry over — the technician learns nothing new.
Same panel, same archive
Data lands in the same place as the 4G model. Even with a mixed fleet, reading, archive and billing stay one system.
Light data use
Index traffic is small; 2G bandwidth is enough for periodic and daily reading.
Suited to
- Extending a fleet that already runs on 2G
- Projects where budget decides the specification
- Short-term or temporary installations
- Regions where 2G still runs reliably
Not suited to
- Countries that have announced a 2G shutdown date
- Installations expected to run untouched for a decade
- Crowded lines above 20 unit loads
Questions
If the 2G network shuts down, does the device become unusable?
Shutdown is regional and gradual. For installations expected to last we recommend the 4G model; the 2G one suits fleet extension and short-term work.
Can both models run on the same project?
Yes. The panel does not care about device type; both attach to the same project and loop structure and write to the same archive.
How much data does it use?
Index packets are small, so low-quota M2M lines are enough for most projects. The exact figure depends on reading frequency and meter count.
