Spatial analysis and modeling of non-ionizing radiations using a two ray approach

Abstract:

This paper uses a Two Ray approach for modeling the spatial diversity of Non-Ionizing Radiations measured at Prosperina campus of Escuela Superior Politécnica del Litoral (ESPOL), located in Guayaquil, Ecuador. Several measurements were made in the installed base stations of the two operators on campus, where we applied an improved version of the measurement procedure defined by the International Telecommunications Union (ITU). The ITU procedure was combined with the one recommended by CENELEC (Comité Européen de Normalisation Electrotechnique). The constructed model was able to simulate the multipath propagation of the transmitted signals, and generated similar values as the ones measured at three different heights at the same location, during the measurement campaigns around the cellular base stations of the two mobile operators on Campus. Finally as a complement, it was also investigated the simultaneous exposure to multiple sources in the closest point to the highest geographic location around Campus, the hill Cerro Azul, since it concentrates the greatest amount of radiating sources from different communication systems.
