Abstract:
Real-time locating systems (RTLS) are used to track and identify the location of objects in real time using simple, inexpensive nodes (badges/tags) attached to or embedded in objects and devices (readers) that receive the wireless signals from these tags to determine their locations. RTLS refers to systems that provide passive or active (automatic) collection of location information.
