What is a high frequency RFID label?
High frequency RFID label is a kind of RFID technology, the operating frequency is 13.56MHz, the wavelength of the frequency is about 22m.
Generally passive-based, the labels work when the number of exchanges must be in the near-field area of the RFID reader antenna radiation. High-frequency labels can be easily made into card-shaped, widely used in electronic identity cards, electronic locking anti-theft (electronic remote control door lock controller), electronic tickets, building access control system, community property management, jewelry inventory management, intelligent shelf management, fixed assets management system, library management system, etc.
UHF labels work at frequencies between 860MHz-960MHz, and can work with different antennas, and can be divided into two categories: active labels and passive labels. When working, the RF label to be in the far field area of the UHF reader antenna radiation field, RFID labels and the coupling between the way for electromagnetic coupling. UHF reader antenna radiation field for passive labels to provide radio frequency energy, will be passive labels wake up. The corresponding radio frequency identification system reading distance is generally greater than 1 meter, the typical situation is 4 meters ~ 6 meters, the maximum can be more than 10 meters. Reader antenna is generally directional antenna, only in the reader antenna directional beam range of radio frequency label can be read/written. UHF label because reads the distance far, transmits the data rate fast, is widely used in the railroad vehicles automatic diagnosis, the container diagnosis, also may use in the highway vehicles diagnosis and the automatic charge system.
The characteristics of high-frequency electronic label and UHF electronic label.
The high frequency label is cheaper than the UHF label, penetrates the non-metal object force strong, the working frequency is not subject to the radio frequency control constraint, is suitable for the object which contains the water component higher, for example the fruit and so on.
UHF label is more expensive, label recognition sensitivity is high, can be read by multiple labels, the role of a wide range, transmission data speed, energy consumption, penetration force is weak, operation area can not have too much interference.
