  • the heating oscillation can be stopped, for example, before an information transmission takes place via the antenna.
  • a mixture of such a sequential transmission and a simultaneous transmission, so for example, a superposition of the information signal on the heating oscillation is possible, for example, to achieve a high data flow and a verification during a sequential transmission period.
  • the communication may include both a data transmission to or from a smart pot and the transmission of a sampling signal or the reception of a reaction signal.
  • control unit for controlling the generation of the heating oscillation for communication by emitting and / or evaluating the information signal and for such timing of generation and communication is provided that the communication during a small period of time in the relative to the Schuschwingungsperiode Range of a zero crossing of the heating oscillation takes place.
