Hardware Design and Deployment Issues in UHF RFID Systems
Recently, radio frequency identification (RFID) have created emerging applications for tracking, sensing, and identifying various targets in wide-ranging areas such as supply chain, transportation, airline baggage handling, medical and biological industry, and homeland security. RFID systems with a variety of radio frequencies and techniques have been introduced. Among them, ultra-high frequenc...
متن کاملEffects of Interferences in Uhf Rfid Systems
The Radio Frequency Identification (RFID) applications are growing rapidly, especially in the UHF frequency band that is being used in inventory management. Passive UHF tags are preferred for these applications. In this paper, RFID reader-to-reader interference is analyzed. A model to estimate the minimum distance between readers to achieve a desired probability of detection in real multipath e...
متن کاملInterference Analysis of Uhf Rfid Systems
In this paper, RFID reader-to-reader interference is analyzed from the point of view of interrogation range. To evaluate RFID interference quantitatively, the new figure-of-merit, interrogation range reduction ratio (IRRR), is defined. In order to show the usefulness of IRRR, its value is calculated in various environments. Additionally, the calculated IRRR values are verified by measurements u...
متن کاملAntenna-Based Passive UHF RFID Sensor Tags - Design and Application
RFID, as a low cost technology with a long life time, provides great potential for transmitting sensor data in combination with the ordinary ID number. The sensor can, for example, be integrated either in the chip or in the antenna of an RFID tag. This thesis focuses on the design of antenna-based UHF RFID sensor tags as wireless sensors at the lowest possible cost level compatible with standar...
متن کاملDesign and Realization of a Uhf Rfid Interrogator
RFID is a generic item which uses radio waves to automatically identify objects and people. This paper presents a flexible RFID interrogator system architecture which could support various kinds of RFID standards and realizes a UHF RFID interrogator based on the EPC global C1G2 standard in details. The proposed interrogator system consists of RF analog front end, digital baseband and MAC layer....
