A comparative analysis of long range and NB-IoT in terms of quality of connectivity

Abstract Long Range (LoRa) and Narrow Band Internet of Things (NB-IoT) are two protocols widely used in IoT applications. They can provide wireless communication between devices with low power consumption and wide coverage. Various researchers have studied the performance of LoRa and NB-IoT. However, analysis about the comparison between the two protocols has not received enough attention. This work aims at comparing the performance of LoRa and NB-IoT in terms of quality of connectivity. First introduces the technical differences between LoRa and NB-IoT, and analyzes the theoretical performance. Then, it operates some tests in real-world scenarios, and compares the practical performances of LoRa and NB-IoT based on the test results. The comparison results show that NB-IoT has a better quality of connectivity than LoRa in most of situations.
