Abstract: A transport container for transporting an object includes an object location to receive the object and a vacuum insulation panel (VIP) to thermally insulate the object location. A sensor unit in the VIP provides a panel condition signal that corresponds to a measurement value of a physical property of the VIP. The physical property influences temperature of the object. A short-distance transmitter unit transmits a first coding of the PCS inside the Container, a long-distance transmitter unit transmits a second coding of the PCS to a remote server for processing the PCS. The server determines a representation of an operation state of the transport container, wherein the operation state is related to the temperature of the object. The material of the VIP is classified and differentiated so that transmitting parameters depend on the material.
