Article: Active RFID And RTLS In Manufacturing By Dr. Peter Harrop, IDTechEx

The ultimate supply chain and the ideal control of parts, materials, work in progress, and finished goods in manufacturing will be provided by Real Time Locating Systems (RTLS), ultimately with sensing as well. These are a form of active RFID and there are various types available from Ultra Wide Band (UWB) which uses a broad range of frequencies in the microwave region, to systems in the megahertz region, though 2.45 GHz is now very popular for RTLS.
