ISO/IEC 18000-7:2014定义了射频识别（RFID）设备的空中接口，该设备作为项目管理应用中使用的433 MHz频段的有源射频标签运行。它提供了RFID设备的通用技术规范，可供制定RFID应用标准的ISO技术委员会使用。ISO/IEC 18000-7:2014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、最大功率、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，以及在适当情况下的工作信道、频率跳变率、跳变序列，扩频序列和码片速率。 它进一步定义了空中接口中使用的通信协议。

ISO/IEC 18000-7:2014 defines the air interface for radio frequency identification (RFID) devices operating as an active RF tag in the 433 MHz band used in item management applications. It provides a common technical specification for RFID devices that can be used by ISO technical committees developing RFID application standards. ISO/IEC 18000-7:2014 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 power, 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.
