TRACKING PALLET GOODS WITH PASSIVE TAGS

원문 (중국어)

To track pallet goods with passive tags, a passive tag is secured to the goods and a mobile tracking device is secured to a pallet that supports the goods. The mobile tracking device transmits an RF (radiofrequency) signal that is received at the passive tag. In response to the RF signal, the passive tag transmits a response message including information (e.g., from an onboard sensor of the passive tag). The mobile tracking device receives the response message including the information and transmits the information to a network (e.g., a wireless personal area network (WPAN, (e.g., Bluetooth, BLE, etc.)), a wireless local area network (WLAN, (e.g., Wi-Fi, etc.)), a cellular network, a satellite network, etc.).
