Evaluación de la atenuación por vegetación de una onda electromagnética utilizando la recomendación ITU-R P.833-10 en la banda de 1.8 Ghz para bosques de pino, ciprés y eucalipto en la ciudad de Riobamba.

Abstract

The ITU-R P.833-10 (Radiocommunication - International Telecommunication Union) provides existing data on vegetation attenuation in various regions. These values, outlined in the recommendation, have been widely utilized for radio link calculations and planning. However, this study was conducted to gather specific, real data applicable to the country. Therefore, the research objective was to evaluate electromagnetic wave attenuation due to vegetation using ITUR P recommendation .833-10 in the 1.8 GHz band for pine, cypress, and eucalyptus forests in Riobamba city. The methodology employed was quantitative, involving real measurements with a descriptive approach. Power measurement values were obtained through vegetation within the frequency range of 1.7 GHz to 1.9 GHz for each tree type and forest. A cross-sectional experimental design was used to ensure the authenticity of the obtained values. The measurements, methods, and techniques were conducted without manipulation, and the study locations, tree heights, and antenna specifications were accounted for. The research determined the attenuation through a single tree and in a pine forest, yielding values consistent with the recommendation. Real values for eucalyptus and cypress were also obtained. In conclusion, the study found that power values and calculations vary based on the environment, soil type, climatic zone, and tree species with their own foliage density.
