The Global Leading Device Manufacturer of 2.4GHz RFID & UHF
What type of rfid tag can send signals over long distances?

April 26,2024.

RFID tags are divided into low-frequency tags, high-frequency tags and ultra-high-frequency tags. The higher the frequency of the RFID tag, the farther the signal can be sent. Therefore, it is best to use ultra-high-frequency RFID tags.

Advantages of ultra-high frequency RFID tags
1. Long-distance reading: UHF RFID technology can achieve long-distance reading, and the typical reading range can exceed several meters or even tens of meters. This means that a large number of objects can be quickly read and identified without touching or coming close to the tag, improving work efficiency.

2. Large-capacity data storage: UHF RFID tags have large-capacity data storage capabilities, usually between a few thousand bits to tens of thousands of bits, or even larger. This allows the tag to store more information, such as the product's serial number, manufacturing date, batch information, etc.

3. High-speed reading and writing: UHF RFID technology supports fast reading and writing operations and can process a large number of tags in a short time. This is very important in the fields of logistics, inventory management and mass production, and can greatly speed up data collection and processing.

4. Simultaneous operation of multiple tags: UHF RFID technology can operate multiple tags at the same time, which is called "multi-tag identification" or "parallel operation". This means that the reader can identify and process multiple tags at the same time, improving the throughput and efficiency of the system.

5. Strong anti-interference performance: UHF RFID technology has good anti-interference performance in terms of antenna design, modulation and demodulation algorithm and spectrum management, and can work stably in complex electromagnetic environments. This makes it suitable for various application scenarios, such as large warehouses, logistics and transportation, retail environments, etc.
