Abstract: The co-frequency coexistence design of narrowband Internet of things (NB-IoT) and cellular networks isstudied. Based on the stochastic geometrytheorem, the location of an NB-IoT user node is modeled by the Poisson cluster process. In addition, analytical expressions of the outage probability and the transmission capacity are derived. Moreover, the outage performance of the heterogeneous network is compared with that of the network modeled by Poisson point process. The impacts of the cluster radius and the density of NB-IoT base stations on the outage performance and the network capacity arealso evaluated. Analytical and numerical results demonstrate that the outage performance and the capacity of the coexistence network can be effectively enhanced by adjusting the cluster radius and the density of NB-IoT base stations.

Key words: narrowband Internet of things, cellular mobile network, Poisson cluster process, outage probability
