Abstract
The disclosure relates to a magnetic communication method that does not use induction. For example, a transmitter device may generate a magnetic field in a controlled direction and rotate the magnetic field around one or more axes. As such, an angle according to which the magnetic field is rotated at the transmitter device may be used as a variable upon which to encode data transmitted to a receiver device that can sense a direction of the magnetic field along two or more axes. Furthermore, to achieve higher data rates, multiple rotation angles could be used to encode the data transmitted from the transmitter device to the receiver device, which may further improve security because reading and/or generating the modulated magnetic field may be increasingly difficult from any significant distance away from the transmitter device and the receiver device.
