ISO/IEC 18000-4:20 08是为使用射频识别（RFID）技术识别物品（物品管理）而制定的一系列国际标准和技术报告之一。ISO/IEC 18000-4:20 08定义了支持ISO/IEC 18000-1的2.45 GHz协议。每个特定物理/数据链路配置在单独的子条款中定义。配置描述包括物理层和数据链路层。ISO/IEC 18000-4:20 08定义了在项目管理应用中使用的2.45 GHz工业、科学和医疗(ISM)频段中工作的射频识别(RFID)设备的空中接口。ISO/IEC 18000-4:20 08为RFID设备提供了通用的技术规范，可供制定RFID应用标准的ISO委员会使用。ISO/IEC 18000-4:20 08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。ISO/IEC 18000-4:20 08定义了用于技术属性的前向链路和返回链路参数，这些技术属性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、扩展序列和码片速率。ISO/IEC 18000-4:20 08进一步定义了空中接口中使用的通信协议。ISO/IEC 18000-4:20 08包含两种模式。第一种是作为询问器首先说话操作的被动标签，而第二种是作为标签首先说话操作的电池辅助标签。参数表中显示了模式之间的详细技术差异。

ISO/IEC 18000-4:2008 is one of a series of International Standards and Technical Reports developed for the identification of items (Item Management) using radio frequency identification (RFID) technology.

ISO/IEC 18000-4:2008 defines the 2,45 GHz protocols that support ISO/IEC 18000-1. Each of the specific physical/data link configurations is defined in a separate sub-clause. The configuration descriptions include a Physical Layer and a Data Link Layer.

ISO/IEC 18000-4:2008 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. ISO/IEC 18000-4:2008 provides a common technical specification for RFID devices that can be used by ISO committees developing RFID application standards. ISO/IEC 18000-4:2008 is intended to allow for compatibility and to encourage inter-operability of products for the growing RFID market in the international marketplace. ISO/IEC 18000-4:2008 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. ISO/IEC 18000-4:2008 further defines the communications protocol used in the air interface.

ISO/IEC 18000-4:2008 contains two modes. The first is a passive tag operating as an interrogator talks first while the second is a battery assisted tag operating as a tag talks first. The detailed technical differences between the modes are shown in the parameter tables.
