Experimental results and EMC considerations on RFID location systems

Many efforts where made in the last years in order to develop new techniques for mobile objects identification, location and tracking. Radio Frequency Identification (RFID) systems are a possible solution to this problem. There are many different practical implementations of such systems, based on the use of radio waves from low frequencies to high frequencies. In this paper we present a short review of existing RFID systems, and an in depth analysis of one commercial system, the RFID RADAR. The results are from experiments performed in real life conditions. Also, this paper offers important EMC information regarding the use of high frequency RFID system.
