Improving designing efficiency of antenna-mast structures for cellular communications based on design solutions assessment

Abstract

A study of the individual and cumulative influence of factors on the indicators of metal consumption and unit cost of antenna-mast structures of cellular communication is presented. The high importance of wireless communication and the Internet, as well as the emergence of new faster generation networks in the country, requires construction of a large number of cellular antenna-mast structures. Due to changes in the requirements of cellular operators to bearing capacity of supports, it is necessary to review and adjust existing projects, and selection of new structural elements and sections for current construction conditions with further calculation of the load capacity. To reduce the complexity of design process, it is proposed to make a preliminary assessment of the adopted design solutions in terms of efficiency criteria, which are considered in the study as metal consumption and unit cost of construction and installation works. The numerical value of the criteria is formed in the course of analyzing the experience of building antenna-mast structures according to analogous projects. Based on the data of the conducted studies of quantitative assessment of factors affecting the metal consumption and unit cost, it was found that such indicators are the area, weight and average suspension height of the equipment mounted on the support. Correlation-regression analysis was used to find dependencies and build diagrams between individual factors and indicators of metal consumption and unit cost of construction within the benchmark price. The complex influence of all factors on the performance criteria can be taken into account using the multifactorial regression model formed by the authors. The use of the results of the study will improve the efficiency of designing antenna-mast structures for cellular communication.
