An efficient inter-site interference model for 4G wireless networks

Abstract

Due to the large number of wireless cells that are required for accurately evaluating inter-site interference in cellular networks, computational resources often pose a considerable limitation. In this paper, a novel method for modeling interference at the edges of the region of interest (ROI) of the cellular topology is proposed. While it shares conceptual ground with previous wrap-around techniques, the proposed method can still be applied over existing solutions without distorting their topology, as conventional toroid shaping is not required. Thus, it allows platforms to retain forward compatibility with network planning tools. System level simulations of a one-tier long term evolution (LTE) network have clearly demonstrated uniform interference across the ROI while achieving an almost three-fold increase in computational efficiency over existing platforms.
