摘要： A system and method is disclosed for selecting certain subgroups of radio frequency (RF) tags for querying, communicating, and/or identifying by a base station. The base station sends commands to a group tags within a RF field of the base station. The tags use control logic to determine whether or not they meet certain criteria sent out by the commands. This may cause the tags to change state which either prevents or allows a given tag to participate in an identification process. In this way, a given subgroup(s) of tags meeting certain criteria can be selected for querying, communicating, and/or identifying.

摘要翻译： 公开了一种用于选择用于基站的查询，通信和/或识别的射频（RF）标签的某些子组的系统和方法。 基站向基站的RF字段内的组标签发送命令。 标签使用控制逻辑来确定它们是否符合命令发出的某些标准。 这可能导致标签改变状态，这阻止或允许给定的标签参与识别过程。 以这种方式，可以选择满足某些标准的给定子组的一组或多个标签子组用于查询，通信和/或识别。
