mc90901Selecting 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
