LoRa Physical Layer Principle and Performance Analysis

摘要

The Internet of Things (IoT) finds widespread applications spanning from consumer services such as smart home or domotic to strategic use cases, including infrastructure or energy management. Different technologies have been proposed to support IoT and this paper aims at analyzing the Long Range (LoRA) one. After introducing the main principles of the physical layer, the main contribution is a theoretical performance analysis. Closed-form expression of the symbol and bit error probabilities are derived that are validated by simulation results.
