Packet Error Rate Measurements in Low Power Wide Area Networking Technologies for IoT

This paper presents a long campaign of experimental results carried out to evaluate the performance of LoRa and Wi-SUN network devices under the influence of different channel conditions such as urban centers, hilly locations and line of sight. The measurement setup has varied several parameters such as spreading factor (SF), chip rate, bandwidth, power delay profile, and signal to noise-ratio. Surprisingly, due to frequency diversity, the Wi-SUN technology employing OFDM modulation presented a better performance than the LoRa technology for the non line of sight cases. On the other hand, LoRa exhibited the best performance in the line of sight condition.
