The Internet of Things (IoT) is a rapidly evolving and expanding field, with more and more devices being connected. The proliferation of these devices, coupled with the widespread deployment of networks, has ushered in an era of unprecedented connectivity and data-driven applications. While these advancements promise revolutionary benefits for society and industry, their environmental implications have become a subject of growing concern. This paper presents a study that highlights the different metrics that need to be prioritized to obtain a sober and efficient LoRaWAN network. These metrics, such as the distance, the transmission power, and the spreading factor, will be examined through extensive simulations that recover data for analysis and evaluation of the network’s environmental impact and quality of service. The work focuses on the deployment of gateways in a LoRaWAN network and the configuration of gateways to limit environmental impact while guaranteeing a sufficient level of QoS.
