发明名称 DATA CARRIER FOR TRANSMITTING DATA WITH DIFFERENT TRANSMISSION PARAMETERS
摘要 <p>A data carrier (1) for contactless communication with the communication station comprises firstly a reception stage (3) for receiving an interrogation signal (IS), secondly a generation stage (17) for generating a response signal (RS) upon reception of the interrogation signal (IS), thirdly a processing circuit (18) for processing the response signal (RS) into a transmission signal (MCRS) suitable for transmission to the communication station, fourthly a determination device (22) for determinating at least one representative value (REP1, REP2), the representative value (REP1, REP2) representing the field strength of the field acting on the data carrier (1), and fifthly a control connection (25) between the determination device (22) and the processing circuit (18), wherein the processing circuit (18) can be influenced via the control connection (25) in order to vary a transmission parameter of a transmission signal generated by the processing circuit (18) as a function of the at least one representative value (REP1, REP2).</p>
