The advent of IoT in addition to the emergence of new technologies, such as LoRaWAN networks, made it possible to capture, process and send sensed information over large areas. However, in order to be able to transmit data over long distances and still guarantee efficient and reliable communication, LoRa devices generally have a large number of transmission parameters. For example, a device can be configured to use different spreading factors, bandwidth settings, encoding rates and infinite distance possibilities, resulting in several possible configurations and different Packet Loss Rates. It is a challenge to determine which of these parameters has the greatest influence on the Packet Loss Rate of the network. Thus, this work presents an analysis of the impact of the transmission parameters on the Packet Loss Rate, through the Multiple Correspondence Analysis technique, applied using R Language. The network submitted to evaluation is implanted in the city of Passo Fundo - Rio Grande do Sul, which was developed by the company Optim (resident UPF Parque). The results showed that the transmission distance is the parameter that most influences Packet Loss. It was also possible to observe that the transmission parameters have a low influence on the loss, when compared to other factors such as gateway latency due to the type of connection used by it.
