Method And System For Magnetic Field Based Information Transfer

Disclosed herein are various systems and methods for transmitting information using modulated magnetic fields. A system comprises a transmitter having a first magnetic field source for transmitting a first modulated magnetic field to a receiver for decoding and a field controller coupled to the first magnetic field source for controlling the first modulated magnetic field. The system can further include a receiver having a first magnetometer configured to detect the first modulated magnetic field produced by the first magnetic field source and a decoder coupled to the first magnetometer for interpreting the first modulated magnetic field. 本文公开的是，用于使用调制的磁场传输信息的各种系统和方法。系统包括发射机，发射机具有用于传输第调制的磁场到接收机用于解码的第磁场源以及耦合到第磁场源用于控制第调制的磁场的场控制器。该系统可以进步包括接收机，接收机具有配置成检测由第磁场源产生的第调制的磁场的第磁力计和耦合到第磁力计用于解释第调制的磁场的解码器。
