METHOD FOR WIRELESSLY RECEIVING AND TRANSMITTING ELECTROMAGNETIC RADIATION, AND ELECTRONIC DEVICE THEREFOR

The present invention relates to a method for wirelessly receiving and transmitting electromagnetic radiation and to an electronic device thereof, the method comprising: - wirelessly receiving (401) a first electromagnetic radiation; - storing (403) energy of the received first electromagnetic radiation in an energy storage; - determining (404), from the amount of energy stored, whether energy stored in the energy storage should be provided to a demodulator and a comparator and/or to a modulator and a transmitter such that they are switched; - wirelessly receiving a second electromagnetic radiation; - demodulating the second electromagnetic radiation so that a first signal is generated, - comparing (407) the first signal with a set of signals; - wirelessly receiving a third electromagnetic radiation; - modulating the third electromagnetic radiation into a fourth electromagnetic radiation by using two different modulations, thereby modifying data contained in the third electromagnetic radiation; - wirelessly transmitting the fourth electromagnetic radiation.
