Narrowband IoT (NB-IoT) as a low power cellular data protocol on the u-blox SARA-N2

In the process of looking at embedded radio components, I came across the u-blox SARA-N2, a low power device designed to provide low bandwidth cellular data coverage for Internet of Things devices - “low power consumption and extended coverage” being the operative buzzwords. Speeds are 227 Kbps down and 21 Kbps up, and it’s claimed to be “low power” though no specific power consumption figures are provided. It’s built on NB-IoT standards that are standardized in June 2016 by the 3GPP project and which are codified in their Release 13. »
