Diseño de un sistema de antenas distribuidas multi-operadora para mejorar la cobertura celular 3G en el edificio de la Facultad de Ingeniería Eléctrica y Electrónica de la Escuela Politécnica Nacional

Abstract

This project establishes the characteristics of WCDMA cellular coverage in the FIEE/FIQA building at National Polytechnic School and it is designed a solution to improve the signal levels using a Distributed Antenna System (DAS) with multi-operator support. According to the physic parameters and the geographic position of the nearby stations to the building, are determined theoretically and also simulated the expected signal levels inside the building through the application of several propagation models for outdoors and indoors environments in Matlab. Furthermore, it is determined the combination of outdoor/indoor models closest to reality based on a comparative between the simulations and measurements of coverage made with mobiles of engineering. Finally, it is designed a multi-operator DAS and the improvement that would be obtained if the design is implemented was quantified using the prediction tool iBwave DESIGN.
