Sensor Area Network for Active RTLS in RFID Tracking Applications at 2.4GHz

Power strength or Received Signal Strength Indicator (RSSI), a primary technique used in Real Time Location Systems (RTLSs), is analyzed in this paper for RFID (Radio Frequency IDentification) tracking applications. Critical issues are studied and hardware novelties are introduced in order to improve its performance. The main novelty is the accomplishment of an RFID RTLS through a mesh of individual active Radio Frequency (RF) barriers composed by active emitter and receiver nodes/tags that cover only small individual areas.
