  • Data carrier with modification means for modifying the load period
    Patent number: 7907897
    Abstract: In a data carrier (1), there are provided modification means (19) for modifying, as a function of the distance between the data carrier (1) and the base station (4), the ratio of the duration of a load period (TB) to the duration of an off-load period (TE), at which ratio the data carrier (1) load-modulates the electromagnetic field (HF) generated by a base station (4).

  • Method and Rfid Reader for Communication Via Radio Channel
    Publication number: 20080297316
    Abstract: A method of communication between an RFID reader (1) and a plurality of transponders (2a, 2b) via a radio channel (20) is disclosed. The method comprises the steps of measuring a noise level (SN) of the radio channel (20), selecting an error correction algorithm (ECA1, ECA2, . . . ECAx) depending on the result of the noise level (SN) measurement, and setting both the RFID reader (1) and the transponders (2a, 2b) to the selected error correction algorithm. Furthermore, an RFID reader (1) is disclosed, which is adapted to perform the method according to the invention.

  • Rfid Reader With An Antenna And Method For Operating The Same
    Publication number: 20080211635
    Abstract: An RFID reader (1, 1?) comprises a signal generator (2) for generating high frequency electrical signals (ES) and an antenna (3) to which the high frequency electrical signals (ES) are feedable in a symmetric mode. The RFID reader (1) further comprises tuning means (4, 4?) for maintaining the antenna (3) in a symmetric operating mode, wherein the tuning means (4, 4?) are controllable in dependency of varying coupling impedances (CG) occurring between the antenna (3) and its environment (G).
