rfid reader distance measurement 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. View scores and results from week 1 of the 2016 NFL Postseason

The transmission power of RFID reader is the key factor to determine the reading distance of RIFD chip. The greater the transmission power, the louder the “voice” of the reader and the greater the distance over which the signal is transmitted. The read range of RFID tags refers to the maximum distance at which the readers can successfully capture the data from the tags. Understanding the read range is crucial for implementing RFID systems effectively and optimizing their performance.
Read range is the distance from which an RFID tag can be detected. The read range expresses the distance from which the tag receives just enough power to be activated to send back a signal to the reader. As the radio-wave speed is a constant, we can calculate the distance of the tag based on that delay. We can then set readers to interrogate only tags within this distance. We recently tested a prototype of a distance-sensing RFID system and achieved distance measurement accuracy of about 0.5 meter.
rfid reader maximum distance
The distance from which a tag can be read is called its read range. Read range depends on a number of factors, including the frequency of the radio waves uses for tag-reader communication, the size of the tag antenna, the power output of the reader, and whether the tags have a battery to broadcast a signal or gather energy from a reader and .
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.This article emphasizes selecting the right RFID chips for different uses and explores the factors affecting RFID chip reading distance.

I know 2 of these methods: The “RSSI method”, that measure the signal strength, and the “radar” method, that measure the time between signal emission and Tag answer reception. The RSSI sounds not easy to use, so I’m looking for a signal transit time measuring.
