High Frequency VS Ultra High Frequency: a question of reach
The choice of radio frequency and thus of label type depends on:
- the required RFID reach (the distance required between the reader and the microchip)
- the desired memory capacity
- the level of security expected for the application
In short, High Frequency (HF) chips fit applications for which the reading distance is less than 1 meter and Ultra High Frequency (UHF) chips are more appropriate for applications requiring a reading distance of way beyond 1 meter, sometimes up to 15 meters, depending on the capacity of the reader.
Several international standards regulate the manufacturing of RFID Microchips and their implementation. Amongst others, they govern:
• Range of radio frequency used
• The maximum field strength for HF RFID
• The maximum transmit power for UHF RFID
• Communication protocol between the RFID reader and the microchip
• Interoperability of the RFID systems
Paragon Identification, leading French manufacturer of RFID labels, respects standards ISO 14443, ISO 15693 and ISO 18000.
