In this paper, we perform the analysis of cost effective capacity expansion strategies with incremental deployment aspects of the forthcoming mobile heterogeneous networks from beyond 4th and 5th generation. We consider different over time (up to year 2025) increasing traffic volumes in order to determine the most cost-effective capacity expansion that would minimize aggregate incremental cost. In this aspect, we determine that deployments with base stations having smaller ranges offer a lower investment risk on long term, because incremental capacity can be satisfied in smaller stages. This is especially due to the fact that the cost structure of smaller base stations is dominated by operational expenditures as compared to, in the other extreme, a new macro base station site. From this perspective, our techno-economic analysis proposes a model that would be useful to analyze the economic viability of different type of traffic growth volumes and for various forthcoming heterogeneous network configurations.
