Abstract: Provided are an active Radio Frequency IDentification (RFID) tag applied to a logistics tracking system and a communication method thereof. The communication method includes transmitting movement completion information to a reader by using a communication channel, which less consumes power of a battery, at a time when movement of a product or a pallet which is moving is not sensed, receiving a request message, requesting position information of the tag corresponding to the movement completion information, from the reader by using the communication channel, activating a positioning channel, which relatively more consumes the power of the battery, to transmit positioning information to the reader by using the activated positioning channel in response to the request message received through the communication channel, and when the transmission of the positioning information is completed, deactivating the positioning channel. The movement completion information indicates movement completion of the moving product or pallet.

Abstract translation: 提供了应用于物流跟踪系统的有源射频识别（RFID）标签及其通信方法。 通信方法包括：在没有感测到正在移动的产品或托盘的移动时接收到请求消息，请求位置的时候，通过使用消耗电池功率的通信信道将移动完成信息发送给读取器 与移动完成信息相对应的标签的信息，通过使用通信信道从读取器激活相对更多地消耗电池功率的定位信道，通过使用激活的定位信道来响应于发送定位信息到读取器 通过通信信道接收到的请求消息，并且当定位信息的发送完成时，停用定位信道。 移动完成信息表示移动产品或托盘的移动完成。
