nRF9160 - Putting the "smarts" into Smart meters

Whether it’s a water-, gas- or electricity meter, it can be connected directly to the cloud with the means of a cellular modem, where LTE-M and NB-IoT are paving the way for a power efficient way to connect smart meters to existing cellular infrastructure.

The nRF9160 SiP supports both LTE-M and NB-IoT for worldwide coverage. Register for this webinar and learn why cellular connectivity is such a big trend in utility metering, see how the nRF9160 SiP can help solve some key battery lifetime and use challenges, and understand how to use the nRF9160 either as a fully integrated solution or as a modem only.
