calculate direction of rfid tag Is there a way to calculate/estimate the physical distance to a long-distance passive RFID tag when reading it with a tag reader? E.g. to determine the order of books in a shelf, or telling if one object is close or far away. Save and categorize content based on your preferences. Near Field Communication (NFC) is a set of short-range wireless technologies, typically requiring a distance of 4 cm or .

Is there a way to calculate/estimate the physical distance to a long-distance passive RFID tag when reading it with a tag reader? E.g. to determine the order of books in a shelf, or telling if one object is close or far away. I’ve got an IR+RFID guided robot. I have to target many objects in a room, one after the other. All are in a random position. Each one is RFID passive-tagged. I proceed like .

All are in a random position. Each one is RFID passive-tagged. I proceed like that: I target an object with the IR, I reach it, and I check .By applying RSSI filters you can optimize RFID reading and writing conditions for specific applications, so that only tags within a certain distance are registered. Ultimately, understanding how RSSI value works will give you more control over your RFID management system. For RFiD readers, Circular polarization antennas allow the reader to read tags in various orientations within the sensing range of RFID reader. This does not mean the RFID is generating RF power from all directions like a dipole antenna.
Pitch is when the tag rotates along the x-axis. Yaw is when the tag rotates along the y-axis. Roll is when the tag rotates along the z-axis. Understanding how an RFID tag’s pitch, yaw, and roll affect your ability to read the tag is key to achieving maximum readability in almost any RFID system.
The basic algorithm is that the tag movement direction is estimated by measuring the time difference of two antennas. The merit of this method is that the direction of each tag can be estimated independently. The conventional sensor system can detect only for the bulk in the case of many tags.
Read range plays a key role in the life of an RFID tag and is one of the factors that determines a tag’s overall use. However, relying on read range alone will direct you to choose a tag that may not actually work for your use case.In this research project, only one RFID reader is used to estimate the position of the RFID tag. Due to the low read range of a passive RFID reader, only one RFID reader is not enough to cover a normal indoor space. Therefore, multiple RFID readers are needed to cover the indoor space. By using the statistics of the tags’ number in different antenna beam directions, a weighting algorithm is used to calculate the position of the tag. This method can be applied to real-time.
