This book explores a novel approach to ultra-low-power and long-range wireless communication for next-generation Internet of Things (IoT) devices through LoRa-based backscatter technology. It begins by analyzing the challenges in traditional IoT systems – energy consumption, scalability, interoperability and security – before introducing backscatter communication as a promising alternative. By leveraging LoRa’s long-range capabilities and the energy efficiency of the backscatter technique, it proposes a solution that significantly reduces power consumption while preserving effective communication performance.

Long-range Low-power Devices Based on LoRa Backscattering for Next Generation IoT Applications presents theoretical foundations, system architecture and tag design, including various modulation schemes and front-end implementations. Several real-world applications are examined, such as indoor localization, smart medical implants, wearable health monitoring and smart home automation. Through practical experiments and performance evaluations, it is demonstrated that LoRa backscattering systems offer a viable and scalable path toward sustainable, maintenance-free IoT nodes. This book serves as a comprehensive reference for researchers and engineers specializing in low-power wireless communication systems for IoT.
