    The rapid growth of smart devices and the IoT paradigm require ubiquitous communication systems that natively integrate internet services with low power consumption. LoRa stands out for its energy efficiency, broad transmission range and ease of implementation. This document focuses on the analysis of this technology in different environments of the province of Azuay, with the objective of obtaining trajectory loss models that allow the design and analysis of LoRa networks, although, a first analysis in these environments, variables such as the height of the gateway, size of payload and transmission power were not taken into consideration. In a previous work it was found that the RSSI values lower than -110 dBm delivered by the LoRa 900 Evaluation Kit are not reliable to be used in the model or in the statistical comparison. Using the Dunn test, it was shown that modification of the trajectory loss model taking into account the payload size is not necessary, since all the configuration variations analyzed are related. The results of the model constants proved to have a linear relationship with the height of the equipment, so the initial logarithmic model was modified taking into account the height, in addition the model constants of the analyzed environments are exposed for use in the loss model of LoRaSim.
