Abstract
A method and system for determining a real-time location of an object or person in a facility using low frequency magnetic induction positioning is disclosed herein. Each of the plurality of low frequency receivers is configured to receive a signal packet from a low-frequency magnetic induction transmitter, decode the signal packet, and estimate a distance from the low-frequency magnetic induction transmitter to the low-frequency receiver based on the decoded signal packet.
