TELE2 IOT introduces NB-IOT only simcards for use in the Netherlands. Narrowband IOT is an LPWAN network that exists alongside the 2G, 3G and 4G mobile networks. It reduces the cost of connectivity and provides long life for battery-dependent devices. NB-IOT only in this context means that the SIM cards can only be used in the Netherlands and that there is no fallback to 2G or 3G.
Practical examples of the use of NB-IOT are: remote reading of groundwater or surface water levels by means of innovative sensors, unlocking valuable data with sensors placed in homes and collecting measurement data from inverters that are linked to solar systems.
