Mediciones espaciales en la banda de frecuencia de 944 MHz a 951 MHz en la ciudad de Riobamba.

Abstract

Spatial measurements were made in a sector of the city of Riobamba divided into 46 measurement nodes, using the NARDA SRM-3000 equipment and a wooden support. which simulates the Duke Virtual Family model. With the data obtained, the maximum, minimum, average and standard deviation electric field intensity values ​​were determined for each measurement node. Subsequently, through the use of plane wave theory, the values ​​of magnetic field intensity and power density were obtained in order to be able to compare these values ​​with the current international regulations of the ITU, specifically in its recommendations K.52 and K. .61, which are based on ICNIRP regulations, and those in force in Ecuador regulated by ARCOTEL. After collecting, processing and analyzing the data, these were tabulated in three tables, one for each value obtained considering Electric Field, Magnetic Field and Power Density; subsequently, the maximum numerical value of each of the three tables was chosen to compare it with the ITU, ICNIRP and ARCOTEL regulations. It was determined that the values ​​for both electric field intensity, magnetic field intensity and power density obtained from the 46 measurement nodes do not exceed the limits established by the aforementioned regulations. It is recommended that the spatial measurements be carried out in accordance with the parameters established by the regulatory entities and that the same procedure applied to different areas of the city of Riobamba be carried out. The data obtained in this article will serve to carry out other studies focused on determining the SAR for the whole body and at 10 grams, and to carry out an electromagnetic mapping of the measurement sector of the city of Riobamba.
