In this work, some experimental results aiming to assess the performance of LoRa modulation are presented taking in consideration two specific scenarios (namely, a dense urban area and a forest environment). These scenarios have been chosen since they are very prone for environment monitoring and protection. The considered LoRa performance criteria are Range, Packet Reception Rate (PR) and Received Signal Strength Indicator (RSSI). The obtained experimental results have provided valuable information on how LoRa modulation can be influenced according to specific environment characteristics as well as combination of them. In addition, experimental results shows that, using a particular LoRA setup, packet loss may be near zero even with a high signal attenuation demonstrating the LoRA robustness feature.
