AT&T says customer demand prompted NB-IoT launch

AT&T has decided to add narrowband IoT (NB-IoT) to its network toolbox because some customers are asking for a lower-cost IoT solution, and because the NB-IoT technology is a better fit for some use cases. The carrier already offers LTE Category 1 and LTE Category M1 for customers who want to connect assets and equipment to the IoT, but AT&T says NB-IoT opens up new use cases.
