    • A transponder and a method for wireless data transmission is provided. The transponder comprises an input circuit with input terminals for connecting an antenna coil for data transmission to a base station by means of inductive coupling, a first controllable switching means, at least one resistor, which is looped in series with the first controllable switching means between the input terminals of the input circuit, and a controller which is designed in such a way that it connects through the first switching means as soon as a voltage applied at the input terminals falls below a first settable threshold value, and again interrupts it as soon as the voltage applied at the input terminals for a settable duration is above the first settable threshold value and/or above a second settable threshold value.

    • In one embodiment, a method includes receiving a carrier signal transmitted by a base station according to either a first data-transmission protocol or a second data-transmission protocol; detecting a first field gap in the carrier signal indicating initiation of a data transmission by the base station; and determining whether a reference duration is present in the carrier signal after the first field gap. The method includes, if the reference duration is present in the carrier signal after the first field gap then, according to the first data-transmission protocol, determining a calibration value for the data transmission based on the reference duration and decoding the data transmission by measuring durations between successive subsequent field gaps and determining whether each duration as measured is a binary 1 or binary 0 based on the calibration value.
    • 在一个实施例中,一种方法包括:根据第一数据传输协议或第二数据传输协议接收由基站发送的载波信号; 检测所述载波信号中的第一场间隙,指示由所述基站发送的数据; 以及确定在所述第一场间隙之后的载波信号中是否存在参考持续时间。 该方法包括:如果参考持续时间存在于第一场间隙之后的载波信号中,则根据第一数据传输协议,基于参考持续时间确定用于数据传输的校准值,并通过测量来解码数据传输 连续的后续场间隙之间的持续时间,并且基于校准值确定测量的每个持续时间是二进制1还是二进制0。
