Abstract
A method of managing objects in a site includes producing a guided surface wave with a guided surface waveguide probe, the guided surface wave having sufficient energy density to power object identification tags in an entirety of a site; receiving reply signals from the object identification tags, each object identification tag associated with an object; and identifying geolocation of one or more the objects according to received reply signals from the object identification tags that are associated with the one or more of the objects.
