<內容簡介>
This book explains how UHF tags and readers communicate wirelessly. It 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. 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.
New to this edition:
‧ Examples of near-metal antenna techniques
‧ Discussion of the wakeup challenge for battery-assisted tags, with a BAT architecture example
‧ Latest development of protocols: EPC Gen 1.2.0
‧ Update 18000-6 discussion with battery-assisted tags, sensor tags, Manchester tags and wakeup provisions
Key Features
*The only book to give an understanding of radio communications, the underlying technology for Radio Frequency Identification (RFID)
*Praised for its readability and clarity, it balances breadth and depth of coverage
*New edition includes latest developments in chip technology, antennas and protocols

商品描述(中文翻譯)
這本書解釋了UHF標籤和讀取器如何進行無線通信。它讓讀者了解標籤讀取範圍的限制,如何增加讀取範圍(以及為什麼這可能違法),以及在設計和實施RFID技術時需要處理的實際問題。本書避免了繁重的數學,但提供了廣泛的覆蓋範圍和適量的細節,是需要了解標籤和讀取器工作原理的工程師的理想入門指南。
本版的新增內容包括:
- 近金屬天線技術的示例
- 針對電池輔助標籤的喚醒挑戰的討論,並提供了BAT架構的示例
- 最新的協議發展:EPC Gen 1.2.0
- 更新18000-6討論,包括電池輔助標籤、感應標籤、曼徹斯特標籤和喚醒條款
