Abstract
A method of tracking an object including producing a guided surface wave with a guided surface waveguide probe, the guided surface wave having sufficient energy density to power object identification tags across an area of interest; receiving return signals from a tag of interest at plural receivers, the tag of interest associated with an object and the receivers that receive the return signals change over time as the tag moves with the associated object in the area of interest; and identifying a series of geolocations at which the object was present as a function of time according to the received reply signals from the tag.
