Transforming IoT Connectivity

As the Internet of Things (IoT) rapidly evolves, it fosters numerous innovative applications that connect low-data-rate, low-power devices. Traditional wireless technologies struggle to meet these connectivity needs, leading to the exploration of Low-Power Wide Area Networks (LPWAN) for long-distance communication. This book addresses critical challenges in LPWAN technologies for large-scale deployments, including transmission conflicts, weak signals, and interference from diverse protocols. We present a novel collision decoding mechanism that enhances network throughput, a weak signal enhancement mechanism for improved signal quality in complex environments, and a wide-area heterogeneous interconnection technology for effective communication across different technologies. Our large-scale deployment, connecting thousands of smart city devices, validates the effectiveness of these solutions, providing a vital resource for researchers and practitioners in IoT connectivity.
