Reliability improvements to healthcare patient RFID tracking with multiple tags

In recent years, a tremendous amount of development has been seen in the field of Internet of Things (IoT) enabled solutions, triggering the advent of novel applications. This evolutionary trend has been led in part by radio frequency identification (RFID) and smart technologies, among others. Inspired by the endeavors in this area, the results reported here apply to a smart architecture for patient tracking and monitoring within hospitals. The aim is to implement RFID based solutions to tracking patients location and movement and expensive equipment in hospitals. Experimental results are reported of a novel patient tracking system that uses of multiple RFID tags in bracelets worn by patients to reliably determine their location within certain area. We also present results on processing the phase of the received signal in order to detect movement of a patient.
