Resumen

This article describes the characterization of a wireless channel model from the Rumiwasi archaeological site, based on Received Signal Strength Indicator (RSSI) using LoRa technology for one-slope log-normal model and two-slope log-normal model, for trajectories: non-line of sight (NLOS) and line of sight obstruction (LOBS), for which an analysis of their respective parameters was made and the most suitable model for each trajectory was chosen; RMS delay spread time of the most representative Inca walls of this archaeological site is also presented, of which a comparative analysis of the attenuation of each of these are made and how they influence the RSSI for the NLOS and LOBS trajectories.
