Investigating the Effect of Temperature in RFID Technology

Radio Frequency Identification (RFID) technology has been adopted and widely used in many applications including agriculture, forest industry, hospitals, highway transportation, and manufacturing industry. Due to its advantages such as tracking and real-time monitoring. RFID technology uses the tag to store limited data that can be read by RFID reader through the antenna. Passive RFID technology is commonly used in industry because of no power source requirement on the tag. Instead, the tag uses the electromagnetic energy transmitted from the reader, which creates significant interference between readers, to transmit stored data. Many literatures focus on the electromagnetic interference (EMI) between antennas to investigate the effect and find the solution. However, noise is another important factor in wireless communication, which may impact on the reading rate in RFID, because RFID uses the small range wireless communication to read the transmitted data from the tag. In this paper, we consider two factors, distance and temperature, to investigate how they affect the RFID read rate. The data collected at various temperature will be compared to the results from normal temperature and the effects of temperature in RFID will be discussed.
