Opis

Near field communication devices and the emerging field of Internet of things (IoT) require efficient, short range communication techniques. Classical telecommunication theory, on the one hand, has so far focused on radiating electromagnetic signals, which is more suited to terrestrial communication systems, but on the other hand, considerable research and applications of inductive methods have emerged in the last decade as innovative approaches for secure, short range communications by changing the paradigm of an established model of electromagnetic communications. Humanity has witnessed the emergence of embedded inductive medical devices, magneto-inductive waveguides, inductive pots and cooking devices, magneto-inductive sensors, wireless power transfer, inductive hearing aids, and inductive point-to-point communication specifically termed near-field communication (NFC) as used in mobile phones and payment cards. While there exist a large set of distributed methods and algorithms detailing the design and performances of such applications, a significant gap is observed as a lack of detailed collection of the methods in one place that could be readily accessible and easily understood.

Principles of Inductive Near Field Communications for Internet of Things fills this gap with the required details and the theory of near field communication systems, including both the radiating and reactive (energy coupling) near-field systems as well as the well known far field radiation techniques. It details the fundamental expressions and design methods which facilitate the creation of near field devices and equipment including embedded biomedical implants. The book contains recent advances in inductive communications, performance, limitations, and a collection of applications. It also lays a strong foundation for the application of inductive methods for creating IoT systems.

The topics discussed in the book include:
- Near field and far field methods
- Circuit models of inductive antennas
- Inductive methods in embedded medical devices
- Range and capacity extension methods including multiple-input and multiple-output inductive systems
- Coding and modulation techniques
- Narrowband and broadband methods
- Magnetic link budgets
- Crosstalk
- Magnetic induction waveguide devices and a Near field Simulator in Matlab

This book is a compendium of design methods for inductive near field technologies and is ideal for design personnel in the wireless communication industries as well as academic staff and master/research students in computer science, wireless sensors, telecommunications systems research, electrical engineering, and IoT. It is a useful guide for undergraduate students to appreciate the role of inductive circuits and magnetism in telecommunications and electronic devices in general.
