标准摘要
[中文适用范围]： 本部分定义了工作在 135 kHz 以下的射频识别 (RFID) 设备的空中接口。本部分 ISO/IEC 18000 的目的是为 RFID 设备提供通用的技术规范，供开发 RFID 应用标准的 ISO 委员会使用。本部分 ISO/IEC 18000 旨在允许兼容性并鼓励国际市场上产品的互操作性。本部分 ISO/IEC 18000 定义了用于 interrogator（读写器）和 tag（标签）之间通信的物理层，并进一步定义了空中接口中使用的通信协议。本部分 ISO/IEC 18000 定义了两种类型的标签：A 型和 B 型，它们仅在物理层上有所不同。两者都支持相同的库存（防碰撞）和协议。A 型标签由读写器永久供电，包括在标签到读写器的传输期间，并在 125 kHz 下工作。B 型标签由读写器供电，但在标签到读写器的传输期间除外，并在 125 kHz 或 134.2 kHz 下工作。 [外文原描述]： ISO/IEC 18000-2:2009 defines the air interface for radio frequency identification (RFID) devices operating below 135 kHz. The purpose of ISO/IEC 18000-2:2009 is to provide a common technical specification for RFID devices that can be used by ISO committees developing RFID application standards. ISO/IEC 18000-2:2009 is intended to allow for compatibility and to encourage inter-operability of products in the international marketplace. ISO/IEC 18000-2:2009 defines the physical layer used for communication between the interrogator and the tag and further defines the communications protocol used in the air interface. Two types of tag are defined by ISO/IEC 18000-2:2009: Type A and Type B, which differ only by their physical layer. Both support the same inventory (anti-collision) and protocol. Type A tags are permanently powered by the interrogator, including during the tag-to-interrogator transmission, and operate at 125 kHz. Type B tags are powered by the interrogator, except during the tag-to-interrogator transmission, and operate at 125 kHz or 134,2 kHz.
