Known and Unknown Facts of LoRa

Abstract: Long Range (LoRa) is a Low-power Wide-area Network technology designed for the Internet of Things. In recent years, it has gained significant momentum among industrial and research communities. Patented by Semtech, LoRa makes use of chirp spread spectrum modulation to deliver data with promises of long battery life, far-reaching communication distances, and a high node density at the cost of data rate. In this article, we conduct a series of experiments to verify the claims made by Semtech on LoRa technology. … Show more

“…In essence, these results corroborate that the relief of the installation area and the environment are key factors of the LoRaWAN network deployment, as concluded in [19,14]. It was possible to reach a distance greater than 30 km in the rural area, according to points P 39 to P 46 , so that neighboring municipalities could be reached as well.…”

“…However, still in the urban area, point P 33 is more than 3 km away. Unlike the other furthest points in the urban area, P 33 presents clear LoS, that is, like [19] we highlight the importance of a clear LoS between the aplication and the gateway. Although the simulation performed with CloudRF does not contain obstacles, the results of the practical assessment corroborated the simulation results regarding the signal coverage.…”
