Base station siting primarily considers factors including construction costs, signal coverage, signal strength, and network capacity. This publication addresses the performance criteria of Base Station Antennas (BSAs), by making recommendations on standards for electrical and mechanical parameters, by providing guidance on measurement and calculation practices in performance validation and production, and by recommending methods. To address these challenges, this paper constructs a multi-objective base station site selection model that simultaneously minimizes costs, maximizes coverage contributions, and minimizes interference. It achieves quantitative balance among objectives through normalization and weight fusion, while. In case of any existing or perceived difference in contents between such versions and/or in print, the prevailing version of an ETSI deliverable is the one made publicly available in PDF format at www. Users of the present document should be aware that the document may be subject. The present document can be downloaded from the ETSI Search & Browse Standards application. If site selection is inaccurate and determined without reference to any previous parameters, the connection between mobile phones and base stations can be often interrupted and calls can. The current release of the publication provides recommendations on standards for para - meters describing an Active Antenna Systems (AAS). Specifically, electrical, mechanical and Electromagnetic Field (EMF) exposure related parameters and a format for electronic data exchange are introduced.
