Abstract: An RFID network, comprising a plurality of RFID read/write devices, which are connected to a central controller via a communication network, has problems as the network size increases. The mutual interference potential on the air interfaces increases, high demands are placed on the communication network with respect to availability, and the efficiency of the controller per RFID write/read device decreases. If part of the resources and the intelligence of the controller are distributed to, or forwarded to, an RFID system unit comprising the RFID read/write device, some of the load is removed from the controller. The RFID system units are notified of the operating sequences to be performed via a mission and said sequences are performed largely synchronously so that the interference potential decreases. Due to the distributed intelligence, the demand with respect to the availability of the communication network likewise decreases and the central controller can provide more resources for processing applications. The RFID network is therefore easier scalable in size and more reliable in operation.
