标准范围

本文件定义了在物品管理应用中使用的860 MHz至960 MHz工业、科学和医疗（ISM）频段工作的射频识别（RFID）设备的空中接口。它为RFID设备提供了一个通用的技术规范，可用于制定RFID应用标准。本文件旨在为国际市场上不断增长的RFID市场提供兼容性并鼓励产品的互操作性。它定义了用于技术属性的前向和返回链路参数，包括但不限于工作频率、工作信道精度、占用信道带宽、最大有效各向同性辐射功率(EIRP)、杂散发射、调制、占空比、数据编码、比特率、比特率精度、比特传输顺序，以及在适当的情况下，工作信道、跳频速率、跳频序列、扩展序列和码片速率。它进一步定义了空中接口中使用的通信协议。本文件规定了无源反向散射、询问器先通话（ITF）系统的物理和逻辑要求。该系统包括询问器(也称为读取器)和标签(也称为标签)。询问器通过向标签发送连续波(CW)RF信号来从标签接收信息；标签通过调制其天线的反射系数来响应，从而向询问器反向散射信息信号。该系统是ITF，即标签仅在被询问器指示之后才用信息信号调制其天线反射系数。本文件规定-询问器和标签之间的物理交互(通信链路的信令层)；-询问器和标签之间的逻辑操作程序和命令；-用于识别多标签环境中的特定标签的冲突仲裁方案；-允许使用ISO/IEC 29167加密套件的可选安全命令。

This document defines the air interface for radio frequency identification (RFID) devices operating in the 860 MHz to 960 MHz industrial, scientific, and medical (ISM) band used in item management applications. It provides a common technical specification for RFID devices that can be used to develop RFID application standards. This document is intended to allow for compatibility and to encourage inter-operability of products for the growing RFID market in the international marketplace.
It defines the forward and return link parameters for technical attributes including, but not limited to, operating frequency, operating channel accuracy, occupied channel bandwidth, maximum effective isotropic radiated power (EIRP), spurious emissions, modulation, duty cycle, data coding, bit rate, bit rate accuracy, bit transmission order, and, where appropriate, operating channels, frequency hop rate, hop sequence, spreading sequence, and chip rate. It further defines the communications protocol used in the air interface.
This document specifies the physical and logical requirements for a passive-backscatter, Interrogator-Talks-First (ITF) systems. The system comprises Interrogators, also known as readers, and tags, also known as labels. An Interrogator receives information from a tag by transmitting a continuous-wave (CW) RF signal to the tag; the tag responds by modulating the reflection coefficient of its antenna, thereby backscattering an information signal to the Interrogator. The system is ITF, i.e. a tag modulates its antenna reflection coefficient with an information signal only after being directed to do so by an Interrogator.
This document specifies
- physical interactions (the signalling layer of the communication link) between Interrogators and tags;
- logical operating procedures and commands between Interrogators and Tags;
- the collision arbitration scheme used to identify a specific tag in a multiple-tag environment;
- optional security commands that allow the use of crypto suites of ISO/IEC 29167.
