Patent abstract
Systems and methods for operating a tag system. The methods comprising: wirelessly communicating, from a tag, a first signal at a first frequency spectrum that allows a tag reader to detect the first signal, when the tag is not proximate to an antenna modulation marker or when the antenna modulation marker has a first orientation relative to the tag; and performing operations by the tag to wirelessly communicate a second signal at a second frequency spectrum that does not allow the tag reader to detect the first signal, when the tag is proximate to the antenna modulation marker or when the antenna modulation marker has a second different orientation relative to the tag.
