Abstract
The present disclosure provides a device and method for producing low-frequency magnetic-field signals to enable long-range wireless communication through conductive media. The magnetic-field signals can be generated by mechanically moving permanent magnets. In some examples, transmitters are capable of transmitting signals in the ultra-low and very-low frequency ranges (e.g., 100 Hz-30 kHz), utilizing a small amount of power.
