Modelling and performance analysis of mmWaves and radio-frequency based 3D heterogeneous networks

International audienceThis study introduces a three-dimensional (3D) model for K-tier heterogeneous networks (HetNets) in order to evaluate the performance of using millimetre wave (mmWave) and radio-frequency (RF) bands. The model is based on 3D stochastic geometry that describes the different cells' positions in the network with realistic constraints. Based on the 3D model, the successful transmission probability, the average throughput, and the average bit error rate expressions of down-link HetNets are detailed and derived for both considering bands. Using numerical results, the analytical derived expressions are evaluated, and the advantages of using mmWave and RF bands for HetNets are investigated
