1. A method for determining the position or orientation of a transponder (110) by inductive coupling in a radio system, the radio system including a transceiver (100) comprising antenna means (102), comprising the steps of:

  • generating a magnetic alternating field by means of the transceiver (100) and the antenna means (102); and

    determining an association signal representing a measure of inductive coupling between the antenna means (102) of the transceiver (100) and the transponder (110), wherein a distance or orientation of the transponder (110) to the antenna means (102) may be associated to the inductive coupling.
