Simulation for blockage sensitivity evaluation of millimeter wave cellular in urban scenarios

The advantage of the millimeter wave and highly directional antenna array have been proved to be possible to achieve the requirement of the 5G in satisfying the high data rate and massive connection with ultra low latency. However, the commercialization of the 5G network requires a deep understanding of the channel behavior of the wireless link in the millimeter wave band. In this paper, system level simulation is developed for the millimeter wave communications system which emulates the physical channel of 60 GHz radio wave based on quasi-deterministic method. In the simulation, in order to compensate the propagation path loss found in this band, the base station and the users are supposed to be equipped with 2D array antenna which forms 3D beam pattern. The simulation helps to evaluate the effect of the beamforming of the quality of the connection and effect of the blockage caused by obstacles like foliage, humans, vehicles, etc. Using numerical simulation results, we validate and demonstrate how beam directionality and random blockage impact the throughput of arbitrary located users in a mmWave network.
