标准摘要
[中文适用范围]： 本文件规定了在860 MHz至930 MHz工业、科学和医疗（ISM）频段内用于物品管理应用的射频识别（RFID）设备的空中接口。本文件旨在实现产品之间的兼容性，并促进国际市场上日益增长的RFID市场的互操作性。本文件定义了前向链路和回传链路的参数，包括但不限于工作频率、工作信道精度、占用信道带宽、最大有效等向辐射功率（EIRP）、杂散发射、调制方式、占空比、数据编码、比特率、比特率精度、比特传输顺序、工作信道、跳频速率、跳频序列、扩频序列和芯片速率等技术属性。此外，本文件还定义了空中接口中使用的通信协议。本文件规定了被动反向散射、询问器先发言（ITF）或仅在监听后发言（TOTAL）RFID系统的物理和逻辑要求。本文件与ISO/IEC 18000-61、ISO/IEC 18000-62、ISO/IEC 18000-63和ISO/IEC 18000-64一起，对860 MHz至930 MHz频段的以下内容进行了规定：——询问器和标签之间的物理交互（通信链路的信令层）；——询问器和标签的操作程序及命令；——在多标签环境中用于识别特定标签的碰撞仲裁方案。 [外文原描述]： This document specifies the air interface for radio frequency identification (RFID) devices operating in the 860 MHz to 930 MHz Industrial, Scientific, and Medical (ISM) band used in item management applications. This document is intended to allow for compatibility and to encourage inter-operability of products for the growing RFID market in the international marketplace. This document 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) or tag-only-talks-after-listening (TOTAL) RFID system. This document, together with ISO/IEC 18000-61, ISO/IEC 18000-62, ISO/IEC 18000-63 and ISO/IEC 18000-64 specifies the following for the 860 MHz to 930 MHz range: — physical interactions (the signalling layer of the communication link) between interrogators and tags; — interrogator and tag operating procedures and commands; — the collision-arbitration scheme used to identify a specific tag in a multiple-tag environment.
