We characterize the SINR in both uplink and downlink channels of ultra-dense networks, which is then used to derive the coverage probability and the NB-IoT’s capacity. The performance results show the effectiveness of the number of repetitions to reduce the block error rate for different densities of transmitters.5357417engNarrow-band Internet of Things (NB-IoT)Performance evaluationjournal article10.1109/lcomm.2022.3151324
