Selecting RFID Frequency

Posted Aug 22, 2011 3:18:15 PM by DecisionPoint Team & filed under

MC3090-Retail_2-small1RFID solutions improve accuracy and overall operations across a wide range of industries by providing identification, location and tracking capabilities. But RFID comes in many different frequencies, such as Low Frequency (LF), High Frequency (HF) and Ultra High Frequency (UHF). All RFID technologies work in similar ways, but each has its own set of performance characteristics that determine the applications they’re best suited for. Understanding these characteristics is important when selecting the technology for your RFID applications. Motorola Solutions recommends asking yourself the following questions to help with the selection:

  1. What is the minimum and maximum distance between tags and readers?
  2. Do you need to read one tag at a time or many tags simultaneously?
  3. Are you tracking items that are relatively inexpensive or high cost items?
  4. How much information do you need to store on tags?
  5. Do you need to conduct payments or other transactions with RFID-enabled devices?
  6. Where do you need to read tags? For example, as assets move in and out of the loading dock for receiving and shipping? As assets pass through specific areas?
  7. How sensitive is the data on the tag? What level of security will the data require?

Be sure to check back later this week as I take a closer look at each type of RFID technology and the typical applications they’re used for.
