HERRERA RUBIO, Jorge Enrique; MORENO VILLAMIZAR, José Yecid  and  ROLON RODRIGUEZ, Blanca Mery. Software to obtain a statistical propagation model in real time. LogosCyT [online]. 2020, vol.12, n.3, pp.128-137.  Epub Nov 27, 2020. ISSN 2145-594X.  https://doi.org/10.22335/rlct.v12i3.1266.

The research process was based on the design of a desktop application for indoor and outdoor coverage testing of wireless links in the 2.4 GHz frequency band with the use of free software, which allows capturing, processing, analysing, calculate and generate a real-time statistical type mathematical model of the media access control (MAC) hardware embedded in a laptop's wireless network card that detects power level, carriers, and other variables within frames of information transmitted by base stations. The methodology is experimental. First, different propagation models are analysed, next existing test tools are studied, and then hardware and software technologies and tools are compared. The programming language is selected and finally the code and the graphical interface of the application are generated in order to visualize the mathematical model expressed through the use of least squares with the Leven-berg-Marquardt algorithm and then compare it with recognized propagation models.

Keywords : propagation; radio link; statistical; software; model.
