mmWave and Time-of- Flight Technologies for IoT

The accelerating growth of the Internet of Things (IoT) has demanded sensing technologies that are not only highly precise but also energy-efficient and scalable across a wide variety of applications. Among these technologies, millimeter-wave (mmWave) and Time-of-Flight (ToF) sensors are gaining increasing attention for their ability to provide robust distance measurements and motion detection in both indoor and outdoor environments. However, capturing data is only one part of the equation - transmitting this data reliably and efficiently is equally crucial. This compact book presents a focused overview of mmWave and ToF sensing technologies and how they can be effectively integrated with modern low-power wireless communication protocols such as BLE, LoRa, and NB-IoT. By grounding the discussion in theory and supported by real-world use cases drawn from scientific publications, this book is intended to serve engineers, researchers, and students seeking to explore the practical side of smart sensing in IoT systems.
