Claim:
1. A method comprising: determining a first strength of an electric field and a second strength of a magnetic field, the electric field and the magnetic field associated with an electromagnetic signal sent from a transmitter; determining a difference between the first strength and the second strength; and determining a transmitter distance based on the difference between the first strength and the second strength; wherein the difference is a first difference and further including: determining a first phase associated with the electric field and a second phase associated with the magnetic field; and determining to determine a second difference between the first phase and the second phase, wherein the weight applier is structured to determine the distance based on the second difference; wherein the distance is determined based on the first strength and the second strength; further including determining a set of weights based on estimated distances, the set of weights including a first weight corresponding to the first difference, a second weight corresponding to the second difference, a third weight corresponding to the first strength, and a fourth weight corresponding to the second strength.
