Abstract
A method and transponder for wireless data transmission between a base station and a transponder is provided by means of inductive coupling, the transponder supports a first data transmission protocol type and/or a second data transmission protocol type. In the first data transmission protocol type, the data transmission is ended when a maximum value for the duration between successive field gaps is exceeded and in the second data transmission protocol type, after the initiation of the data transmission a reference duration is transmitted by the base station, by means of which the calibration value is determined in the transponder, whereby the calibration value is used for calibrating subsequently received durations. The reference duration is selected as greater than the maximum duration value.
