Performance Analysis of Small Cell Networks Using Accurate Path Loss Model at 39 GHz

Abstract

In this paper, we apply an accurate millimeter wave (mmWave) path loss model, obtained from outdoor measurement operated at 39 GHz in Qingdao, China, into the stochastic geometry analysis to investigate the system performance of small cell networks (SCNs) with non-identical user equipment (UE) - base station (BS) antenna heights. The analytical expressions for coverage probability and outage probability are derived in detail, which are functions of BS density and absolute difference between the antenna heights of BS and UE. The analytical results of coverage probability and outage probability are verified through Monte Carlo simulation. Our study shows that as the SCNs become denser, the impact of antenna heights difference on coverage and outage probability is more significant.
