ABSTRACT:
An improved compact, secure localization tag useful for identifying and tracking the tag in an environment comprising discrete areas is disclosed. Further, systems and methods for area-based localization of tags using received signal strengths is also disclosed. Tracking the location of an asset can be facilitated by attaching a tag that transmits a beacon signal to the asset. The beacon signal can be received and measured by beacon receivers so as to locate the asset and the attached tag.
