Low Power Wide Area Networks based on LoRA Technology

The demand for connected devices, according to the Internet of Things (IoT) paradigm, is expected to grow considerably in the immediate future. Various standards are currently contending to gain an edge over the competition and provide the massive connectivity that will be required by a world in which everyday objects are expected to communicate with each other. Among these standards, Low-Power Wide Area Networks (LPWANs) are continuously gaining momentum, mainly thanks to their ability to provide long-range coverage to devices, exploiting license-free frequency bands. The focus of this thesis is on one of the most prominent LPWAN technologies: LoRa™. First, this thesis establishes a series of models that cover various aspects of a LoRa network. Then, a new Network LoRaWAN Simulator is introduced to simulate a LoRa-based IoT network of four use cases. Finally, the performance of the LoRa system is evaluated and analyzed.
