English abstract:
In this paper, we investigate the impact of femtocell deployment density and femtocell isolation on the downlinkperformance of Orthogonal Frequency Division Multiple Access (OFDMA)-based macrocellular Long Term Evolution (LTE) networks by system level simulations. Femtocell isolation is defined as the separation between macro- and femto tiers by wall penetration loss. We evaluate the relation between user throughput and femtocell density for highly-isolated and nonisolated deployments. The system model is based on a Poisson Cluster Process and simulations are carried out with the Vienna LTE system level simulator. We provide results for Signal-to- Interference-Plus-Noise Ratio (SINR), throughput, fairness and gain over non-femtocell-enhanced networks. Our investigations indicate a femto-networks high sensitivity to varying wall penetration loss and we observe that in dense deployments, average user throughput conceals the severe performance degradation of macrocell-attached users. The whole simulation environment together with the fully reproducible results of this paper are made available for download on our homepage.
