For data transmission from the HITAG S Transponder to the RWD, the implemented method is called 'load modulation'.
Here the HITAG S Transponder continuously changes the load on the magnetic field, by in principle turning on/off a
resistor, according to the information to transmit. Alteration of the magnetic field is detected by the receiver of the RWD.
The modulation ratio of the RWD antenna voltage depends on the coupling factor of the antenna configuration (RWD
antenna size, transponder antenna size, distance between the antennas,...).
