Caracterización de materiales para acabados de construcción en la sierra ecuatoriana para la evaluación del desempeño de la tecnología wifi en ambientes indoor.

Abstract

The main objective of this titling work was to characterize the materials for construction finishes in the Ecuadorian highlands for the evaluation of the performance of Wi-Fi technology in indoor environments. For which the analysis of the state of the art of the characterization of materials in the 2.4 and 5 GHz bands was carried out, the main characteristics of the equipment and instruments to be used in the test scenarios were detailed, the general properties of five most common materials for construction finishes that are Gypsum, marble, PVC ceiling, MDF wood and porcelain, but also of two additional materials such as a concrete block and a brick wall, power measurements were made in the receiver which were carried out in the frequency bands from 2400 to 2500 MHz and 5170 to 5815 MHz with steps of 5 MHz, measurements were carried out under unhindered conditions, with one hurdle consisting of the main material, and with two hurdles involving the main material together with additional material. The difference between the received power in the presence and absence of obstacles represents the insertion loss associated with said material. In addition, coverage, transmission speed, latency and packet loss measurements were also carried out. The results obtained in the 2.4 GHz band of insertion losses are 1.24 dB in PVC ceiling, 1.85 dB in MDF wood, 1.49 dB in Gypsum, 2.47 dB in porcelain tile and 3.16 dB in marble, while for the 5 GHz band there are insertion losses of 1.77 dB in PVC ceiling, 3.07 dB in MDF wood, 3.17 dB in Gypsum, 4.12 dB in porcelain tile and 5.24 dB in marble.
