A Method of Dynamic Small Cell Deployment in 5G Two-Tier HetNet for Improved Area Spectral Efficiency

In this paper, we present a cluster evaluation method to determine the optimal small cell density (SeNBs) in a 5G two-tier HetNet distributed through spatially clustered Non-Homogeneous Poisson Point Process (NHPPP). Incorporation of SeNBs is observed for Area Spectral Efficiency (ASE). Analytical results revealed that SeNBs with optimal density can improve the ASE in a HetNet even in peak hours considering urban tele-traffic distribution scenarios.
