This textbook offers a comprehensive guideline for integrated data and energy transfer, from theoretical fundamentals to practical implementations and applications. This book is suitable for students, engineers and scientists in electronic engineering who are interested in the integrated data and energy transfer in future wireless networks. The authors cover waveform and transceiver design in the physical layer, resource allocation and medium access control protocol, networking and deployment as well as practical implementation of the wireless integrated data and energy transfer. The authors commence from information theoretical fundamentals, physical layer design principles, medium access control, and networking techniques. The book ends with a practical prototype of integrated data and energy transfer. The book is geared towards graduate students and senior undergrads having a general background of wireless communications. The book features exercises, Q&A, and examples throughout.
