Abstract: An RFID apparatus for communicating with at least one RFID transponder is provided that has an RFID transceiver for radiating and receiving RFID signals and a control unit that is configured to encode RFID information into the RFID signal in accordance with an RFID protocol or to read it from the RFID signal and in which a singulation process is implemented to give a command to only one respective RFID transponder. The singulation process in this respect checks a communication parameter of the RFID signal itself that is independent of RFID information encoded in the RFID signal.

Abstract: An RFID apparatus for compartment occupancy detection in a shelf, the RFID apparatus including an antenna, an RF transceiver connected to the antenna and a control and evaluation unit for communicating with an RFID transponder via the RF transceiver and the antenna by means of an RFID signal and for a detection and localization of changes in the compartment occupancy. The RFID apparatus further includes a plurality of reference transponders to be arranged on the shelf at known positions, wherein the control and evaluation unit is configured to localize, upon a change of a detectable RFID transponder population, an RFID transponder which is removed or added based on the position of a reference transponder where communication characteristics of the RFID communication have changed together with the change of the detectable RFID transponder population.

Abstract: The invention relates to a localization apparatus for radio wave-assisted localization of a transponder, the localization apparatus comprising a control device, an evaluation device, a switching device, a first linear antenna array, and a second linear antenna array. The first antenna array and the second antenna array are controllable independently of one another, are arranged cross-wise with respect to one another, and include an angle not equal to zero between them. The control device is additionally adapted to control the switching device to connect the evaluation device alternately to the first antenna array and the second antenna array. The evaluation device is adapted to determine first and second reception angles at which a radio wave signal of the transponder is incident onto one of the first antenna array and the second antenna array when the first and second antenna arrays are connected to the evaluation device, respectively.

Abstract: An RFID reading apparatus (10) is provided for reading RFID transponders (22) in a reading zone (24) in accordance with an RFID protocol, the RFID reading apparatus having an antenna (16, 26), a receiver (12, 18) for receiving RFID signals of the RFID transponders (22) with the aid of the antenna (16, 26) and an evaluation unit (12, 18) for reading a piece of RFID information from the received RFID signals, wherein the antenna (16, 28) is an external antenna (16) connected via a line (14) and has a display element (30) and/or has an operating element (32) which can be controlled by the evaluation unit (12, 18). In this respect, the external antenna (16) has a communication unit (28) for controlling the display element (30) and/or the operating element (32); and wherein the communication unit (28) is configured to communicate with the evaluation unit (12, 18) via the line (14) in accordance with the RFID protocol.
