Applications of RFID Systems - Localization and Speed Measurement

Many efforts were 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 chapter we present a short review of existing RFID systems and an in depth analysis of one commercial development system. We also present a speed measurement application using the same RFID system. The last section of this chapter offers important electromagnetic compatibility (EMC) information regarding the use of high frequency RFID systems. All results are from experiments performed in real life conditions. EMC and speed measurements were performed in a 3 m semi-anechoic chamber using state-of-the-art equipments.
