4G/LTE cellular M-Bus gateway
NVS Gateway 4G
The standard installation for remote reading. The gateway goes out over the mobile network on its own SIM, reads the M-Bus line and sends the data to the panel. Reading continues even if building management changes or the internet subscription is cancelled — the system does not depend on either.

What it does
Independent of management
It does not depend on the building's internet, its password or its goodwill. A change of management does not interrupt reading.
Survives network shutdowns
2G shutdown schedules keep advancing country by country. A 4G device is unaffected — the system you install stays valid for years.
Carries a daily reading load
Instead of one reading a month, readings come daily; consumption analysis, leak and closed-valve detection all come from that frequency.
Remote configuration
Reading frequency and scope change from the panel — no site visit for every setting.
Suited to
- Buildings with no internet of their own
- Installations expected to run for years without touching
- Portfolios where management changes frequently
- Crowded lines — 60 unit loads
Not suited to
- Locations with no mobile coverage at all
- Budgets where a monthly data line is out of the question
- Wireless (wM-Bus) meters — these need an RF receiver
Questions
Do you supply the SIM?
Either way works. You can fit your own corporate line, or use it with a data line we provide; the choice is settled at quotation.
How is it different from the 2G gateway?
Same function, different network. The 2G model costs less but carries the shutdown-schedule risk. For installations expected to last, 4G is the choice.
How do we know if a gateway goes offline?
Last-seen time and signal level are tracked in the panel. A notification can be set for a device that goes quiet, and a work order sends a task to the field.
How many units does one gateway cover?
The 60 unit loads on the spec sheet map to a unit count that depends on line length and meter type. Projects are split using loops, and each loop attaches to its own gateway.
