Consideration for performance of passive UHF far-field RFID tag to tag interference based localization system

In this research, we studied several factors which impact the performance of passive UHF far-field RFID based localization systems with KNN and LDTI algorithms. According to the empirical results, the localization system can be significantly interfered by distance relative factors such as the true positive reference identification rate and interrogation rates. Moreover, passive UHF RFID based localization systems need to analysis a required localization accuracy and interrogation duration to support RTLS.
