A deep dive into wireless energy transfer technologies for IoT networksIn Wireless Energy Transfer: Towards Sustainable Zero-Energy IoT Networks, distinguished researchers Onel L. A. López and Hirley Alves deliver a robust discussion of massive wireless energy transfer and zero-energy, low-cost, Internet of Things networks. Moving beyond the basic theoretical background of the subject, the authors offer a deep analysis of the scenarios and requirements of wireless energy transfer.The book details novel powering schemes recently proposed to face the challenging requirements of the future Internet of Things, as well as a comprehensive review of sustainable IoT wireless networks.Wireless Energy Transfer explains why novel energy efficient solutions will be needed to address the sheer volume of devices currently forecasted to be used in the near future. It explores the challenges technologists and users will face as well as proposed solutions and future research directions.The authors also discuss: Thorough introductions to wireless energy transfer, including energy harvesting sources, radio frequency energy harvesting circuits, efficiency models, and architectures for wireless energy transfer powered IoT networksComprehensive explorations of ambient radio frequency energy harvesting, including measurement campaigns, energy harvesting hardware prototypes, and performance analysis based on stochastic geometryPractical discussions of efficient schemes for massive wireless energy transfer, including energy beamforming, multi-antenna techniques, and distributed antenna systemsPerfect for students and researchers in signal processing, communications, networking, and information theory, Wireless Energy Transfer: Towards Sustainable Zero-Energy IoT Networks will also earn a place in the libraries of students and practitioners in the fields of communication hardware and transceiver design.

Comprehensive and authoritative resource paving the way for the integration of machine-type communications (MTC) and satellite connectivity toward 6G era This book focuses on the integration of machine-type communications (MTC) and satellite connectivity toward the 6th generation of mobile systems (i.e., the “6G”). Integrating these two technologies, especially within the emerging direct-to-satellite (DtS) concept employing direct connectivity between an MTC terminal and a satellite-based gateway, will be critical in enabling the future Internet of Things (IoT) applications in remote areas with limited connectivity infrastructure available. To this end, the book delivers an in-depth analysis of the drivers, use cases, scenarios, technical aspects, cybersecurity, and mechanisms spanning from the physical layer (PHY) to the application layer, regulation, standardization, and potential business models. In addition, many examples, illustrative figures, and tables support the text. With each chapter written by renowned experts in the field, Integration of MTC and Satellites for IoT toward 6G era contains information on: How to enable wireless connectivity for MTC/IoT devices in remote areas, which hardware and network architectures can be employed, and their pros and cons Fundamental and practical challenges, design dimensions, and perspective technologies for integrated MTC and satellite systems Applications and business areas that would be the first ones to employ DtS and status of standardization and regulation activities in the fieldThe strong tutorial element makes the Integration of MTC and Satellites for IoT toward 6G era a convenient learning resource for students and educators in higher education institutions. Moreover, it is ideal for students obtaining their first professional degree and experts who operate in this or adjacent fields and want to revise and update their knowledge.

This book focuses on the multidisciplinary state-of-the-art of full-duplex wireless communications and applications.
