Abstract
A magnetic induction (MI) repeater includes first and second coils configured to have the same resonance frequency and to be substantially isolated from one another, and an amplifier connected to the first and second coils and configured to receive a signal induced in the first coil by a first magnetic field and output, via the second coil, a second magnetic field based on the signal, wherein the second magnetic field is amplified relative to the first magnetic field.
