Effiziente Kommunikation zur Konfiguration von Sensorknoten
Efficient communication for the configuration of sensor nodes
Embodiments provide a method of transferring data from one device to another device. The method comprises a step of generating a magnetic signal with an electromagnetic functional unit, wherein the electromagnetic functional unit is an actuator of a loudspeaker of the device or wherein the electromagnetic functional unit is an electromagnetic resonant circuit connected to the device, wherein the magnetic signal from the device to the transmits data to another device. Further, the method comprises a step of detecting the magnetic signal with an electromagnetic resonant circuit of the other device to obtain the data to be transmitted from the device to the other device, wherein the magnetic signal FSK is modulated, wherein a resonant frequency of the other of the electromagnetic resonant circuit device and a carrier frequency of the FSK modulated magnetic signal are coordinated with each other.
