Narrowband IoT

Narrowband IoT (NB-IoT) is another category of LTE that is an LPWA technology. It uses similar coverage enhancement techniques as LTE-M but improves upon overall power consumption by utilizing a narrower bandwidth. Consequently, NB-IoT devices support lower data throughput compared to LTE-M.  NB-IoT does not support connected mode mobility and is much less suited to mobile use cases. If a device must be mobile the device's application must manage the mobility and should expect session resumptions at each cell. NB-IoT is well suited to stationary use cases that require long battery life, enhanced coverage, and utilize optimized software to reduce overall data transmission.
