NB-IoT is the most suitable mobile network technology for IoT applications that require exceptionally extensive coverage added with extremely low power consumption, since these applications will generally be characterized by low data rates and moderate reaction times, usually in a few seconds, enabling the creation and development of solutions aimed at smart cities and smart environments. The NB-IoT technology can be characterized as a cellular LPWAN technology operating in a downlink within a bandwidth of 180 kHz and a sub-carrier space of 15 kHz and in the uplink, in general with a single tone transmission ranging between 3.75 kHz or 15 kHz, using coverage enhancement techniques, with characteristics of battery life for more than a decade and with specific battery-saving features. The ease that technological solutions of internet of things (IoT) make available through applications connected through intelligent sensors in traffic lights and parking lots; city pollution sensors; meters for energy, water, and sewage in cities, among other possibilities make systems more efficient, considering NB-IoT connectivity in relation to the treatment of information collected by devices allowing applications to be developed to address market needs. Therefore, this chapter aims to provide an updated discussion on narrowband technologies in the context of the IoT, showing and approaching its success, with a concise bibliographic background, categorizing and synthesizing the technological potential.
