Abstract:
A NarrowBand Internet of Things (NB-IoT) device can find a connection to an NB-IoT cell by searching for an available NB-IoT carrier. An available NB-IoT carrier can be found by scanning through frequencies associated with a plurality of channel numbers on a predefined NB-IoT channel list, the plurality of channel numbers being associated with a plurality of NB-IoT carriers offered by one or more base stations. The NB-IoT carriers are frequency bands within a larger spectrum band associated with a telecommunications provider. The NB-IoT device can camp on a particular NB-IoT carrier when the particular NB-IoT carrier has an available physical resource block (PRB).
