Abstract

LoRa technology, which is increasingly employed in the Internet of Things, implements low-power and long-range networks. Depending on these characteristics, LoRa may or may not be suitable for certain applications. Thus, it is important to understand how power and range depend on network parameters and the scenario. This work analyses the communication between LoRa nodes and their performance according to the distance between them and the spreading factor. The latter is a parameter of the LoRa modulation that reduces the rate of loss with consequent reduction of the transmission rate. For example, the results show that increasing this factor from 7 to 11 reduces the loss rate from 50% to 13% for transmissions at a distance of 2 km.
