Análise da diferença do custo de implantação de Estações Rádio Base no Brasil

Abstract

Base Transceiver Stations (BTSs) are part of the basic infrastructure for the operation of the mobile telephone system. These stations concentrate the reception and distribution of data and allow population connectivity. Due to the need to expand communication and the obligation imposed on the winners of the 5G auction to expand the infrastructure in remote areas, there is a need to implement a significant number of BTSs throughout Brazil today. As these are areas with low population density and bring very low financial returns to operators, installation investments are reduced to make projects viable, meaning that market competitiveness forces a rigid calculation of costs and agility in responding to budgets. Based on this need and seeking to assist a traditional company in the sector, this work aimed to identify the difference in costs of implementing BTSs at national level, in order to guarantee competitiveness and the search for projects that are more profitable for the company. To this end, data on the implementation costs of works already delivered were collected and analyzed, comparing the total and detailed costs between the 5 regions of the country. At the end of this study, it was possible to conclude that the Northeast, Central-West and Southeast regions are the most competitive for the target company and that, on the other hand, the South region has the highest operating costs. Furthermore, it was observed that the most impactful factor in construction cost is the characteristic wind speed of each location, which significantly affects the weight of the vertical structure and the concrete volume of the foundation. With this development, data was made available to improve the company’s assertiveness and competitiveness, in addition to bringing reliability to strategic commercial decision-making.
