AbstractThe NB-IoT (Narrowband Internet of Things) aims to connect a massive number of devices that have low power, low data rate and low energy consumption requirements, in a wide coverage area. This paper presents an analysis of the performance of the NPRACH channel (Narrowband Physical Random Access Channel), in terms of delay and throughput, when a device performs the procedure of random access in an NB-IoT network with three levels of enhanced coverage. The performance results are compared with those of an NB-IoT network operating with only one level of coverage, previously published in the literature.
