## 7 Conclusions and Future Works  
In the literature, there are studies on the radio range of LoRa in geographic areas that do not exceed 1700 m.a.s.l., in which it is stated that the coverage depends on the environment in which the network is implemented. So, this research was conducted, since there are no previous studies that give a detailed explanation of the LoRa network in mountainous areas above 2910 m.a.s.l. in the Andean region of Ecuador.  
The orography impaired the radio-link sensitivity, which was attenuated when located in positions with slopes of 15% with the presence of eucalyptus trees in the environment and without a line of sight with respect to the Gateway. The objective of implementing a monitoring system of climatic variables for the agricultural fields of the community of Chirinche Bajo was achieved.  
In Ecuador, the use of these LoRa networks is very limited due to the technological gap that exists in the Andean areas of Ecuador, in addition to the fact that agricultural processes are not technical due to the low technological knowledge of the population, which hinders the successful implementation of new technologies.  
To evaluate the range and avoid data loss in LoRa radio communication, the propagation factor (SF) was set to 7, 9 and 12, keeping the CR constant at (4/5) and BW at 125 kHz, in order to assess the sensitivity and integrity in the delivery of data packets. The SF setting equal to nine, emerged as the best option to achieve the highest throughput with the shortest packet on-air time. However, the alternative (FS at 12) could also be used to achieve higher coverage. Although, this would depend on the application's tolerance to packet loss. The performance of LoRa communication with an SF of nine achieves a packet delivery success rate (PDR) for uplinks no lower than 76% and a PDR for downlinks higher than 92%.  
The scope of the LoRa network architecture is based on tests conducted in a 50-hectare field with a maximum range length of 875 m without a line of sight, obtaining adequate data delivery. The present work benefited 80 families in the community of Chirinche Bajo in the province of Cotopaxi in Ecuador, through the timely monitoring of climatic variables that mitigate agricultural losses due to adverse climatic effects.  
To increase the autonomy time of the nodes deployed in the crops, a feasibility analysis should be conducted to implement photovoltaic power generators, recharge the batteries and increase the operating time.  
Currently, work is being undertaken to improve security aspects by means of encryption algorithms such as Advanced Encryption Standard (AES) at the moment of transmitting the information.  
In addition, according to the findings of this work, we intend to implement an automated system that allows frost control, a harmful condition that affects agricultural production in the area.
