Analytical Evaluation of an Antenna Array System and Adaptive Cell Densification Technique for Energy Efficient LTE Network

Abstract

This paper will propose a cost effective antenna array system and an adaptive cell densification technique for energy efficient Long Term Evolution mobile radio network. The antenna array system is designed to control the elevation half power beam width and elevation electrical beam down tilt angle by using a low loss novel antenna array feed network. The paper will also propose a novel sectorisation order control technique, which is the amalgamation of horizontal and modified vertical sectorisation with the improved and novel features. The proposed sectorisation order control technique can efficiently deal with uniform and non-uniform angular traffic loads in the dense urban region and therefore the proposed solution is more pragmatic. The results show that the capacity of the mobile radio network can be controlled with the highest possible flexibility by using the proposed cost effective antenna array system and adaptive sectorisation order control technique. The results also show that the 40 % energy can be saved when the traffic load of the base station is less than or equal to the minimum threshold value.
