The trials and rollout of the fifth generation (5G) network technologies are gradually intensifying as 5G is positioned as a platform that not only accommodates exploding data traffic but also unlocks a multitude use cases, services and deployment scenarios. However, the need for hyperdense 5G deployments is revealing some of the limitations of planning approaches that hitherto proved adequate for pre-5G systems. The hyperdensification envisioned in 5G networks not only adds complexity to network planning and optimization problems, but underlines need for more realistic data-driven approaches that consider cost, varying demands and other contextual attributes to produce feasible topologies. Furthermore, the quest for network programmability and automation including the 5G radio access network (RAN), as manifested by network slicing technologies and more flexible RAN architectures, are also among other factors that influence planning and optimization frameworks. Collectively, these deployment trends, technological developments and evolving (and diverse) service demands point towards the need for more holistic frameworks. This article proposes a data-driven multiobjective optimization framework for hyperdense 5G network planning with practical case studies used to illustrate added value compared to contemporary network planning and optimization approaches. Comparative results from the case study with real network data reveal potential performance and cost improvements of hyperdense optimized networks produced by the proposed framework due to increased use of contextual data of planning area and focus on objectives that target demand satisfaction.

“…In [4] the authors propose to deploy a massive amount of small cells in order to increase the total capacity and reduce the energy consumption. The literature [5] studies the impact of network densification in the Manhattan grid city model and shows that cell densification could be a sufficient way to fulfill the capacity demands for outdoor coverage. Therefore, increasing the number of cells has been considered as one of the most obvious methods for enhancing the network capacity.…”

An indoor network planning for large buildings is studied in this paper, where the cells are continuously added in order to increase the total network capacity. The network capacity performance with varying cell densities has been studied with system-level simulations. The results show that under a particular assumption of traffic load, denser small cells per floor may even degrade the downlink performance due to the higher inter-cell interference. However, the uplink performance can always benefit from the cell densification. This paper can serve as essential guidelines for indoor small cell deployment. It is recommended that careful considerations need to be taken if an operator intends to improve network performance by adding cells to their networks.
