Abstract
Deployment of cellular system with frequency reuse of one is critical to support increased data traffic and high data rate applications in 4G and beyond radio interface technologies. Such deployment leads to substantial increase in Inter-Cell Interference (ICI). Therefore, this paper investigates and evaluates the capacity performance of mobile cellular system with a frequency reuse of one and three-sector per Base Station (BS). The communication channel between the BSs and user equipment links is modeled using ITU-R channel model. The study considers different carrier frequencies and different cell ranges. The system performance is assessed in terms of Signal to Noise Ratio (SNR), Signal to Interference plus Noise Ratio (SINR) and ergodic capacity. The SNR and ergodic capacity improve significantly as the cell range and carrier frequency decreases for ICI free scenario. However, for ICI scenario, there are slight variation in the performance when changing the cell range and the carrier frequency. The study recommends a cell size of 800 m.
