Active RFID and RTLS in Manufacturing

For the future, we need to add lower cost, if more primitive, active RFID systems to those successfully deployed in manufacturing today. Then we can tag high volume goods of modest value. Dr Daniel Engels leads a team working on this at the Texas RFID Center in the University of Texas at Arlington. The Korean National Information Agency, with government backing and many industrial partners, has trialled Ubiquitous Sensor Systems employing mesh networked active RFID in six types of location. To conserve power and reduce cost it is now trialling improvements on ZigBee.
