Narrowband IoT (NB-IoT) is a new fast growing wireless technology 3GPP cellular technology standard introduced in Release 13 that addresses the LPWA requirements of the IoT. that was Classified as a 5G technology, istandardized by 3GPP in 2016. It is fast emerging as the best in classa leading LPWAN technology to enable a wide range of new IIoT devices including smart parking, utilities, wearables, and industrial solutions. It is characterized by excellent indoor coverage, support of a massive number of connections, cost efficiency, low device power consumption and optimized network architecture. It can This is due to its ability to efficiently connect large fleets of devices,  - up to 50,000 per NB-IoT network cell - , while minimizing power consumption and increasing coverage range in locations not served by conventional cellular technologies.
