<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

內容簡介
本書解釋了UHF標籤和讀取器如何無線通信。它幫助讀者理解限制標籤讀取範圍的因素、如何增加讀取範圍(以及為什麼這可能會違法),以及在設計和實施RFID技術時需要解決的實際問題。避免繁重的數學計算,但提供了適當的細節,這是對於需要了解標籤和讀取器工作原理的工程師來說,理想的無線通信入門書籍。
本版新增內容:
‧ 近金屬天線技術的範例
‧ 討論電池輔助標籤的喚醒挑戰,並提供BAT架構範例
‧ 協議的最新發展:EPC Gen 1.2.0
‧ 更新18000-6的討論,包括電池輔助標籤、感測器標籤、曼徹斯特標籤和喚醒條款
