Employed IMPINJ R2000 RF Chips, up to 110dbm receiving sensitivity and the highest performance in this field makes this module more suitable for harsh application environment.
High stability and reliability, 60*24 hours high temperature of workstation, can work stably and continuously.
Remarkable performance with 8dbi RF antenna, can achieve a reading distance over 10m per single tag.
Remarkable performance in intensive taps reading can attain a taps identification rate of 400tags/s.
Provide the most comprehensive functions SDK and ports, easy to integrate RFID software.
Adopted integrating RF chip, module performance is more stable, and more suitable for harsh application environment.
The use of carrier wave cancellation technology makes the tag reading more accurate and the reading scope wider.
The smallest module volume in the same field and supply power of 3.7V, it is especially suitable for handsets and other mobile devices.
Enhance noise suppression for reliable data capture.
High precision return signal strength (RSSI).
