Abstract

the frequency bands below 6 GHz, which have traditionally been used for the transmission of wireless communications systems, are saturated. Therefore, the search for new frequency bands has been focused on higher frequencies. In this scenario, characterizing the propagation in bands above 6 GHz for various propagation environments is necessary. In this article, an empirical propagation model is presented to predict indoor propagation losses from 10 to 20 GHz. The model was obtained from measurements carried out inside an anechoic chamber, which was designed and built with an internal cover of polyurethane foam as absorbent material and metallic external cover. Measurements were performed in distance and frequency steps of 10 cm and 50 MHz, respectively. In addition, the atmospheric conditions of temperature, humidity and oxygen level inside the chamber were modified, through the insertion of oxygen and water vapor. In order to emulate the weather conditions of mountainous and coastal places. It was determined that the variation of the oxygen and humidity concentration improves the propagation conditions by 7 dB and 15 dB, respectively.
