Real time location estimation using active RFID system

Abstract

The accuracy issues in the location prediction system using active RFID tags is addressed in this paper. First we present the location prediction accuracy in different environmental conditions. Later on, we propose a new technique to improve the prediction accuracy. The proposed technique is validated with measured data obtained under different propagation environments.

Ultra wideband antenna for real time location system application

“…It is used to track and identify an object's location in real time using simple tag attached/embedded to the objects [5]. Then a device (reader) will be used to receive the wireless signals from these tags to determine their locations.…”

Research on Preventing Consecutive Collision Algorithm for Real Time Location Transmit-Only Tags

“…The RFID technology is used to realize this [1,2] by fixing the tags on the moving objects and determining the location of the objects according to the identity number sent by the tags and collected by the card readers distributed in the underground coal mine. In most cases, the active tags are used in the system to increase the identification distance [3,4], which means the tags will broadcast identity number actively and periodically. To guarantee a longer service time and lower cost of the tags, only transmit-only tags are used [5,6].…”
