The frequency ranges generally used by RF soft labels include the following common standards:
Low frequency:
Frequency range: 125 kHz - 134.2 kHz
Features: Short reading distance, usually between a few centimeters and 10 centimeters, strong anti-interference ability, suitable for animal identification, access control systems, etc.
High frequency:
Frequency range: 13.56 MHz
Features: Reading distance is usually 10 cm to 1 meter, widely used in smart cards, public transportation, library management and other fields.
Ultra-high frequency:
Frequency range: 860 MHz - 960 MHz
Features: Long reading distance, usually up to several meters, suitable for logistics, supply chain management, warehousing and other fields.
Microwave:
Frequency range: 2.45 GHz or 5.8 GHz
Features: Long reading distance, usually up to 10 meters, but greater interference with metal and water, suitable for some specific high-demand applications.
In summary, the frequency range of RF soft labels is mainly between 125 kHz and 5.8 GHz. The specific frequency band to be used depends on the application scenario of the tag and the regulatory requirements of the region.
