Performance Analysis of Vertical Sectorization for LTE Realistic Deployment Scenario

Mobile network capacity demand has been continuous increasing due to increasing penetration of data intensive services. To meet the increasing capacity demand, vertical sectorization has been considered one important capacity enhancing technology through vertical cell splitting into inner and outer cells by applying active antenna system. Planning vertically sectorized network is a new concept and need to be investigated well in order to characterize its impact on cell edge performance and capacity. Although this method presented by different authors, still various issues needs to be further investigated. Analyzing this method in realistic network environment, vendor antenna pattern and effect of spacing between vertical pattern with considering cell edge performance are rarely reported. In this paper, impact of this technology with performance metrics of 5% tile, 50% tile and 90% of CDF of SINR and their modified shannon mapping in realistic environment are examined. Propagation computation is performed using deterministic path loss model and network simulation is made using matlab. According to simulation results the identified 3 x 2 configuration out performs others 3 x 2 studied scenarios. And this configurations can enhance system performance up to 51.8% compared to the existing 3 x 1 network.
