Abstract
Demand for enhanced mobile broadband has been significantly increasing due to increasing penetration of data-intensive mobile services. For accommodating this demand, various network capacity enhancing technologies including cell densification and applying more frequency bands have been investigated and incorporated in the fourth generation (4G) and fifth generation (5G) mobile technologies. Network densification can be performed by either deploying new small cells or further sectoring horizontally and vertically existing network sites. Performance benefits of vertical sectorization have been investigated but mostly for theoretical network environment and user demand distribution that significantly affect the benefits. In this paper, we present performance analysis for vertical sectorization under realistic network environment and user distribution for selected urban area of Addis Ababa, Ethiopia. The analysis is performed for sub-6-GHz bands including those identified for 5G. Network simulation is performed using MATLAB while network modeling and assumptions are developed based on data collected for target area of Addis Ababa from network management system of the Addis Ababa network. Propagation is computed using deterministic 3D ray tracing method based on building map for the target area. Performance results show that considerable performance benefits are achieved by applying vertical sectorization for both cell edge and cell center users. For instance, we observe that 3 × 2 configuration presents 236.6%, 504% and 821.5% user throughput gains compared to 3 × 1 configuration at 10%-ile, 50%-ile and 90%-ile.
