SUMMARY:

In recent years, technological development and advances in the studies of communication systems based on radio-frequency (RF) have fostered several researches, with emphasis on the propagation of RF signals in the indoor environment. However, there is still an unfilled space with regard to research on the influence of construction materials on the propagation performance of these radio signals. This work aims to study the behavior of RF signals when reaching obstacles of building elements based on ceramic blocks, gypsum blocks and concrete blocks, and to experimentally determine the attenuation caused by these materials, which are currently most used in the construction civil. A measurement setup is proposed in this work and samples of these materials were subjected to RF signals in the frequency range between 700 MHz to 2500 MHz.They were analyzed in 03 samples of each type of material and the measured results for the attenuation of the signals were statistically treated and compared. The results indicate that the attenuation of the RF signal depends on the type of material used and its composition, therefore, it is necessary to develop studies in an attempt to propose new materials that meet the strength requirements demanded by civil construction and minimize the propagation losses of these signs in the indoor environment.
