Selecting the right RFID frequency will help you get the most value from your RFID solution. Today I’d like to take a quick look at the different RFID frequencies and their capabilities.
Low Frequency (LF):
Low Frequency systems are typically 125 KHz and this band provides a shorter read range (between 0.5m and 1.5 ft.) than higher frequencies. LF RFID systems can read tags on objects with a higher metal or water content and tend to be less sensitive to interference than higher frequencies.
High Frequency (HF):
High Frequency RFID technology operates at 13.56 MHz. and features a greater read range than LF systems, with a maximum approximate range of 3 feet. HF has long been considered the frequency of choice for item-level tagging. Some common uses for HF RFID include:
- Electronic ticketing
- Contactless payment
- Access control
- Sample tracking
Ultra-High Frequency (UHF):
Ultra-High Frequency systems offer a longer read range and faster data transfer rate than other frequencies, with an approximate range of 10 feet or more. UHF is supported by numerous standards, including EPCglobal Gen 2 and has been commercialized between 858 to 960 MHz. Common uses include:
- Compliance tagging
- Case/pallet Identification
- Work-in-Process tracking
- Asset management
