Base Station Location Optimization in 5G Dense HetNets

Paper Presented at The 5th National Conference on Communications held in Kampala, Uganda, from 17th - 18th October 2019. 

Paper Abstract: Over the last few years, traffic demand has increased exponentially and forecasts show that this trend will continue. Operators have to expand and upgrade their networks to provide the required capacity. As we head into the era of 5G, cellular networks will continue to become ever more heterogeneous in nature, characterized by a dense deployment of small cells. As base stations (BSs) become smaller, they enable more aggressive frequency reuse which results into enhanced capacity. In addition, location and deployment constraints on such cells reduce. It is envisaged that small BSs (sBSs) will be deployed easily on street furniture, simple poles, etc. When the physical locations options increase, the operator ought to pick the best locations for deployment. In this paper, we propose a location optimization algorithm that can be used to choose the best locations subject to a network capacity constraint. Our results show that when the algorithm is applied, the capacity targets can be achieved with few sBSs. In addition, the algorithm significantly enhances the energy efficiency (EE) of the dense heterogeneous network (HetNet).
