Performance Analysis of Vertical and Higher Order Sectorization in Urban Environment at 28 GHz

Abstract

The main aim of this paper is to compare the performance of cellular network using higher order sectorization in horizontal domain, vertical sectorization, and super cell configuration. The urban macrocellular environment from Helsinki city is targeted, and 28 GHz frequency is used as frequency of operation. Conventional three sector site deployment scenario is also included for reference. The comparative analysis is conducted from different dimensions, and the performance metrics considered in this study includes the SINR, inner sector traffic share, server dominance with 3 dB overlapping window, and the spectral efficiency of the system. This research work is carried out by doing 3D ray tracing simulations utilizing "sAGA", a MATLAB based 3D ray tracing tool. It is found more complicated to find the optimal antenna configuration for vertical sectorization and super cell configuration in comparison with higher order sectorization. It is also established from the acquired results that higher order sectorization is more simpler and better approach for enhancing the cell capacity compared with vertical sectorization and super cell configuration. Higher order sectorization provides a spectral efficiency gain of around 96.7%, whereas the relative spectral efficiency gain of vertical sectorization and super cell configuration is limited to 62.8% and 10.6%, respectively, with respect to three sector site deployment.

Data-driven optimal antenna planning for enhanced 4G mobile networks under realistic environment

“…Recent studies, [18]- [22] presented the capacity gains that will be obtained due to cell splitting under theoretical 3rd generation partnership project (3GPP) simulation environments. The performance impact of manipulating antenna parameters such as electrical and mechanical tilt, half power horizontal and vertical beamwidth, and transmit power optimization are presented in [23]- [27]. The researchers [28], [29] experimental works to examine the actual performance of cell densification for single cell single user cases are conducted.…”

Utilizing Non-Orthogonal Polarization With Polarization Reuse Technique for 4 × 4 MIMO Capacity Enhancement

“…MIMO system offers spatial diversity and spatial multiplexing which substantially improves network capacity and spectral efficiency without utilizing more bandwidth and more total system power [8]- [10]. In addition to MIMO system, another cost-effective and practical means of improving spectral efficiency, and consequently enhancing network capacity, is the sectorization of the site, where each site is partitioned into multiple sectors and spectral resources are reused in each sector [11]- [14]. A view of MIMO technique and site sectorization technique is shown in Fig.…”
