CUET PG 2026 Agri-Business Management Question Paper (25-Mar-2026) (Shift 2)
The correct answer is
300 - 950 MHz
UHF RFID Tag Frequency
Ultra High Frequency (UHF) RFID tags operate within a specific radio frequency range. This range is standardized to ensure interoperability and performance.
Determining UHF RFID Frequency
The standard frequency band allocated for UHF RFID systems varies slightly by region, but generally falls within the 300 MHz to 950 MHz range.
- Option 1: 30 - 500 KHz (Low Frequency - LF RFID)
- Option 2: 3 - 30 MHz (High Frequency - HF RFID)
- Option 3: 300 - 950 MHz (Ultra High Frequency - UHF RFID)
- Option 4: 2.4 - 2.5 GHz (Microwave Frequency - often used for Wi-Fi and Bluetooth, sometimes specific active RFID)
Conclusion on UHF Frequency
Based on the standard classifications for RFID technology, the UHF RFID tag operates within the 300 - 950 MHz frequency band. This frequency allows for longer read ranges and faster data transmission compared to LF and HF RFID systems.
