The RF in RFID

Informationen zum Autor Dr. Daniel Dobkin has over four decades of experience in commercial technology development, including wireless communications and RFID, semiconductor processing, process equipment, design, and reliability, and energy storage. He is the author of three technical books and over 40 technical publications. Klappentext Ten years ago when RFID technology came on to the scene, the software tools, processing power and integrated circuits were very basic. However, in the last 3 years there have been considerable improvements in hardware and software, enabling a variety of applications not dreamed of previously in fields such as automotive and medical. For example, RFID technology can be used for monitoring patients' health in hospital beds. This book explains how UHF tags and readers communicate wirelessly. It gives an understanding of what limits the reading range of a tag, how to increase it (and why that might result in breaking the law), and the practical things that need to be addressed when designing and implementing RFID technology. Avoiding heavy math but giving breadth of coverage with the right amount of detail, it is an ideal introduction to radio communications for engineers who need insight into how tags and readers work.

Ten years ago when RFID technology came on to the scene, the software tools, processing power and integrated circuits were very basic. However, in the last 3 years there have been considerable improvements in hardware and software, enabling a variety of applications not dreamed of previously in fields such as automotive and medical. For example, RFID technology can be used for monitoring patients' health in hospital beds. This book explains how UHF tags and readers communicate wirelessly. It gives an understanding of what limits the reading range of a tag, how to increase it (and why that might result in breaking the law), and the practical things that need to be addressed when designing and implementing RFID technology. Avoiding heavy math but giving breadth of coverage with the right amount of detail, it is an ideal introduction to radio communications for engineers who need insight into how tags and readers work.

Zusammenfassung
Explains how UHF tags and readers communicate wirelessly. This book gives an understanding of what limits the read range of a tag, how to increase it (and why that might result in breaking the law), and the practical things that need to be addressed when designing and implementing RFID technology.
