how to get rssi value and tag name rfid In active RFID applications, RSSI is a very important factor for determining the location of a tagged asset. Because an active tag broadcasts its signal instead of relying on signal backscatter, each tag’s RSSI value is proportional to the distance between the .
QUICK ANSWER. NFC tags and readers communicate wirelessly with each other over very short distances. Tags store a small amount of data on them that is sent to the reader in the form of .

In order to avoid interference and read the RFID tags on assets within a selected range of the reader, one must focus on RSSI Value. RSSI value, which is short for Received Signal Strength Indicator, is a standard feature of every localization solution based on wireless .By applying RSSI filters you can optimize RFID reading and writing conditions for specific .
An RFID tag’s RSSI value can range anywhere from - 30 to -92 dBm and the . In order to avoid interference and read the RFID tags on assets within a selected range of the reader, one must focus on RSSI Value. RSSI value, which is short for Received Signal Strength Indicator, is a standard feature of every .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.
In active RFID applications, RSSI is a very important factor for determining the location of a tagged asset. Because an active tag broadcasts its signal instead of relying on signal backscatter, each tag’s RSSI value is proportional to the distance between the . An RFID tag’s RSSI value can range anywhere from - 30 to -92 dBm and the closer the RSSI value is to 0, the better the signal. The more sensitive the RFID reader is, the more likely the reader is to read tags with weak signals.
It's possible to read the RSSI value with EPC Gen2 tags, so if the tag you're referring to supports this standard it should work. Try downloading the Zebra RFID sample app > Perform inventory > If the tag is found it should display the RSSI.
Once clicking on the UID, the "Tag Info" tab opens. The bar on the bottom indicates the RSSI value. By moving the card closer or further away from the antenna, you should see how the bar changes. If RSSI indicates "Link lost" the card is out of the reading range of the reader. 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.

To perform UHF RFID tag writing successfully, it is extremely important to make sure that the passive tag is located within a strong enough reading area. This is possible by utilizing the RSSI value (received signal strength indicator) defined by the reader. The RSSI value is an indication of the distance between the reader and the tag, with a higher RSSI value suggesting closer proximity and a lower value indicating greater distance.
Received signal strength indicator (RSSI) is a measure of the strength of a signal received from a tag. I assume you are talking about passive UHF RFID systems, which use RSSI to determine how close a tag is to a reader antenna. The answer to your question depends on what you are trying to achieve.
