Radio Basics for RFID The following is excerpted from Chapter 3: Radio Basics for UHF RFID from the Book, The RF in RFID: Passive UHF RFID in Practice by Daniel M. Dobkin. Order a copy of The RF in RFID: Passive UHF RFID in Practice before December 3…

RFID读写器的工作原理 RFID的数据采集以读写器为主导,RFID读写器是一种通过无线通信,实现对标签识别和内存数据的读出和写入操作的装置. 读写器又称为阅读器或读头(Reader).查询器(Interrogator).读出装置(Reading Device). 扫描器(Scanner).通信器(Communicator).编程/编码器(Programmer)等等. 读写器工作原理 RFID读写器的基本原理是利用射频信号与空间耦合传输特性,使电子标签与阅读器的耦合元件在射频耦合通道内进行能量传…

Passive RFID Basics - AN680 INTRODUCTION Radio Frequency Identification (RFID) systems use radio frequency to identify, locate and track people, assets and animals. Passive RFID systems are composed of three components – a reader (interrogator), pass…

RFID Exploration Louis Yi, Mary Ruthven, Kevin O'Toole, & Jay Patterson What did you do? We made an Radio Frequency ID (RFID) card reader and, while attempting to create a long-range spoofer, created an jammer which overcomes card's signals. The read…

* 部分资料来自我们博士的PPT,部分来自网络和他人的论文. * 我们使用的教材是清华大学出版社出版的<智能卡技术(第四版)——IC卡.RFID标签与物联网(清华大学计算机系列教材)>(王爱英 主编) * 我仅仅整理了下边的内容 射频识别技术 射频识别(Radio Frequency Identification, RFID)技术是一种非接触自动识别技术,利用射频信号通过空间耦合(电感或电磁耦合)或雷达反射的传输特性,实现无接触信息传递并通过所传递的信息达到识别目的.射频识别技术在国内最广泛的…

A network authentication method is to be implemented using a network authentication device and a user end for authenticating the user end. The network authentication method includes the steps of: configuring the network authentication device to store…

BACKGROUND The following disclosure relates to a method and system for enabling a user to browse physical things using a rich user interface (UI) via a web browser in Internet of Things (IoT) such that an end user has rich experience. Internet of Thi…

A method and apparatus enable Internet of Things (IoT) services based on a SMART IoT architecture by integrating connectivity, content, cognition, context, cloud, and collaboration. Joint optimization of a combination of any of connectivity, content,…

In one embodiment, a network architecture comprises minimalistic connected objects (MCOs), distributed intelligence agents (DIAs), and central intelligence controllers (CICs). MCOs have limited intelligence sufficient to perform their respective desi…
