Locating physical items is a highly relevant application addressed by numerous systems. Many of these systems share the drawback that costly infrastructure must be installed before a significant physical area can be covered, that is, before these systems may be used in practice. In this paper, the authors build on the ubiquitous infrastructure provided by the mobile phone network to design a wide area system for locating objects. This system provide way for monitoring and locating objects using Radio Frequency (RF) transmitters and receivers, and querying about the objects using mobile phones. An object represents a real world entity.
