Asset tracking and supply chain management are important activities across a range of Industrial Internet of Things (IIoT) applications, including manufacturing plants, logistics and distribution centers, data centers, hospitals and health care, agricultural, construction, and transportation. Specifying a passive radio frequency identification (RFID) asset tracking system is complex. Valuable assets can be exposed to various uncontrolled conditions, including shock and vibration, hot, freezing cold, and wet environments during transport and storage, and there are various application-specific RFID standards to be considered.
