The Low-Frequency (LF) band covers the range of 30 KHz to 300 KHz with a typical LF RFID system operating at 125 KHz. This frequency band provides a short 10-15cm range and it has the slowest reading speed compared to the other frequency bands.
The High-Frequency (HF) band covers the range of 3 MHz to 30 MHz with a typical HF RFID system operating at around 13.5 MHz. The HF band provides a wider range and a faster speed compared to the LF band.
The Ultra-High-Frequency (UHF) band covers the range from 300 MHz to 3 GHz. While regional differences can occur, RAIN RFID systems use the UHF Gen2 standard and usually use the 860 MHz to 960 MHz frequency band. The UHF band provides the greatest range and reading speed of all the frequency ranges, providing maximum read performance.
