The working frequency of RFID technology has a certain relationship with the working distance. Generally speaking, the higher the working frequency of RFID technology, the farther the working distance, but it will also be affected by other factors, such as antenna size, power and so on.

This is because electromagnetic waves with high frequency travel farther in the air and have higher penetration. In addition, the high-frequency RFID system can provide stronger signals, thus increasing the range.

However, the higher frequency RFID system also has some disadvantages, such as being susceptible to interference, requiring more complex equipment parts, higher cost and so on. Therefore, in practical application, these factors need to be considered to determine the most suitable frequency to meet specific needs.
