RFID Frequency Ranges Overview

LF, HF, UHF Basics

You need to understand the basics of rfid frequency ranges before choosing the right reader. The three main types are lf, hf, and uhf. Each type uses a different frequency and works best for certain tasks. lf stands for low frequency. hf means high frequency. uhf is ultra-high frequency. These rfid frequency ranges help you match the right reader to your needs.

Here is a simple table showing the main frequency bands and their ranges:

Frequency Band

Frequency Range

Read Range

Low Frequency (LF)

125 kHz and 134 kHz

10 to 50 cm

High Frequency (HF)

13.56 MHz

10 cm to 1 m

Ultra-High Frequency(UHF)

860 to 930 MHz

Varies (typically longer than LF and HF)

lf rfid readers use the lowest frequency. They work well for short distances and simple tasks. hf rfid readers use a higher frequency. They can read tags from a bit farther away. uhf rfid readers use the highest frequency. They can read tags from much longer distances.

Read Range and Performance

You want to know how far each rfid reader can scan. The read range depends on the rfid frequency ranges. lf readers usually scan up to 10 cm. hf readers can reach from 10 cm to 1 meter. uhf readers can scan from 1 meter to 12 meters or more. This makes uhf rfid readers popular for tracking many items at once.

Here is a quick table to help you compare:

RFID Type

Typical Read Range

LF
