标准范围

ISO/IEC 18000-4:20 18本文件定义了在物品管理应用中使用的2.45 GHz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。本文件提供了RFID设备的通用技术规范，可供制定RFID应用标准的ISO委员会使用。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。该文件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、最大等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ra你。该文件进一步定义了空中接口中使用的通信协议。本文档包含四种模式。模式1是询问器首先与被动标签交谈。模式2是标签首先与电池辅助的无源标签通话。模式3是支持（但不限于）物流和运输行业的全球可用、无处不在的网络；与任何设备无关，无论是商业设备还是其他设备，需要全球可用性。模式4是可配置数据速率有源RFID系统。它提供了远距离物体识别和环境感知的功能，旨在实现设备成本低、功耗低、远距离识别、快速可靠的标签存取。参数表中显示了模式之间的详细技术差异。

ISO/IEC 18000-4:2018 This document defines the air interface for radio frequency identification (RFID) devices operating in the 2,45 GHz industrial, scientific, and medical (ISM) band used in item management applications. This document provides a common technical specification for RFID devices that can be used by ISO committees developing 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. 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 equivalent isotropically 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. This document further defines the communications protocol used in the air interface.
This document contains four modes. Mode 1 is an interrogator talks first with passive tag. Mode 2 is a tag talks first with battery-assisted passive tag. Mode 3 is a globally available, ubiquitous network supporting (but not limited to) the logistics and transportation industry; agnostic to any device, commercial or otherwise, requiring global availability. Mode 4 is a configurable data rate active RFID system. It provides the functions of long range objects identification and environmental sense, and it is intended to realize the low cost device and low power consumption, long range identification, fast and reliable tags access. The detailed technical differences between the modes are shown in the parameter tables.
