This article presents the results obtained in the evaluation of the LoRa technology as an alternative communication protocol in rural areas, by making measurements in situ in a rural area between the municipalities of Sibaté and Granada in Cundinamarca, Colombia. Using a document search, the TTGO esp32 board was selected as device for testing. Additionally, a temperature sensor and a variable resistance were included to obtain measurements from a transmitter node, whose data was sent to a receiver node using the LoRa protocol with a distance of 500 meters between them and an approximate elevation gradient of 4° difference between the points. Finally, the information collected in the tests was subjected to a descriptive statistical analysis that allowed establishing the most reliable parameters of the protocol and identifying the appropriate spreading factor and bandwidth.

Keywords : LoRa technology; rural testing; wireless communication.
