Abstract: An RFID device is provided for communicating with at least one RFID transponder that has a transmitter, a receiver, a transmission antenna and a reception antenna for emitting and receiving RFID signals and has a control and evaluation unit that is configured to transmit and receive an RFID signal in a respective one of a plurality of frequency channels, in particular to encode RFID information into the RFID signal and/or to read information from the RFID signal in accordance with an RFID protocol and to carry out an intensity adaptation of the RFID channel in dependence on the frequency channel used for the transmission and reception.

Abstract: An RFID reading apparatus (18) for bin occupancy recognition in a shelf (10) is provided having at least one antenna (16), an RF transceiver (20) connected to the antenna (16), a control and evaluation unit (22) that is configured to communicate with an RFID transponder (24) by means of RFID signals via the RF transceiver (20) and the antenna (16), and having at least one additional sensor (24) for detecting objects at or in the shelf (10). In this respect, the control and evaluation unit (22) is configured to recognize and locally associate changes of the bin occupancy from a combination of information of the antenna (16) and information of the additional sensor (24).

Abstract: An RFID reading apparatus (20) for shelf occupancy detection comprises an elongated antenna (18) with an outer conductor (26) and an inner conductor (28) arranged in the outer conductor (26), an RF transceiver (22) connected with the antenna (18), and a control and evaluation unit (24) configured to communicate with an RFID transponder (14) via the RF transceiver (22) and the antenna (18) by means of RFID signals. The outer conductor (26) comprises a plurality of slot structures (16) over its longitudinal extent each for transmitting and receiving RFID signals.

Abstract: An RFID reader device (10) for reading an RFID transponder (36) is provided, the RFID reader device (10) comprising an antenna (16) for the transmission and/or reception of an RFID signal and at least one transceiver unit (18) connected to the antenna (16) to transmit and/or receive the RFID signal using antenna parameters. The antenna (16) comprises a data carrier (26) wherein the antenna parameters are stored, and the transceiver reception unit (18) is configured to access the data carrier (26) to read the antenna parameters.
