Why UHF RFID Is Preferred in Industrial Applications
UHF RFID operates in the ultra-high frequency band (860–960 MHz), which offers several advantages over LF and HF RFID in industrial settings:
-
Longer reading distance
-
Faster data transmission
-
Ability to read multiple tags simultaneously
-
Strong anti-collision performance
-
Compatibility with global RFID standards
This makes UHF RFID ideal for process automation, asset identification, and logistics tracking.
