UHF Long Range Reader ADVANTAGE
For youPoints of service To provide you with 100 minutes of service
  • It is best to install at  a 45-degree angle from the horizontal line.

    We suggest you test the detecting effct before installment.

  • We need to do a self-check firstly:


    - we use the demo software,connect UHF readers.and then click set parameter

    - we can take UHF reader to another more empty place to test,avoiding signal interface

    - pay attention to the installment angle for UHF reader

    - check if there is other things covered on cards or labels

    - check if this UHF cards or tags aging or not

    - Check if your UHF cards are from us or not.and if they are EPC GEN2 ISO18000-6C

  • Please ask sales the profile ‘deal the same number for WG data’

  • If so,we can try USB to RS232 converter.Or use RS485 interface.

  • ISO 18000-6 is an international standard governing the way tags and readers communicate in the UHF spectrum. 

    There are currently three versions: 18000-6A, 18000-6B and 18000-6C. Of these, 18000-6C is by far the most commonly used.

  • EPC Gen 2 was designed to work internationally and has other enhancements that are significant, 

    but the real benefit of Gen 2 is that it works anywhere in the world and major manufacturers of chips and tags have lined up behind it.

  • The answer to these questions is that just about any asset, part, product or other item can be identified, tracked and managed using 

    an ultrahigh-frequency RFID tag. But tagging methods vary, based on an item's shape, size, material and texture, 

    as well as the environmental conditions in which it will be tracked.Among the key issues that must be considered, as below:


    • the size of the asset to be tagged and the footprint available to receive the tag

    • the surface of the asset to be tagged, such as metal, plastic, cloth, living tissue (nursery stock, farm livestock, lab animal, 

       pets, infants), wet paint, wet chemical coating, chemically treated, abrasive


    • the duration of time the asset needs to be tagged—short or long term, permanent or temporary


    • the duration of time the item will be exposed to environmental conditions, such as extreme temperatures, moisture, 

      chemicals, abrasion, dust, human contact, pressure, salt water, animal exposure, outdoor ultraviolet exposure and weather conditions, 

      industrial processing, temperature shock (going from hot to cold and back), flash freezing (dry ice), and lab testing


    • the asset's temperature at the time of tagging; for example, hot molded products just out of the mold, or frozen consumer vending products

  • The distance from which a tag can be read is called its read range. Read range depends on a number of factors, including the frequency of the radio waves uses for tag-reader communication, the size of the tag antenna, the power output of the reader, and whether the tags have a battery to broadcast a signal or gather energy from a reader and merely reflect a weak signal back to the reader. Battery-powered tags typically have a read range of 300 feet (100 meters). These are the kinds of tags used in toll collection systems. High-frequency tags, which are often used in smart cards, have a read range of three feet or less. UHF tags-the kind used on pallets and cases of goods in the supply chain-have a read range of 20 to 30 feet under ideal conditions. If the tags are attached to products with water or metal, the read range can be significantly less. If the size of the UHF antenna is reduced, that will also dramatically reduce the read range. Increasing the power output could increase the range, but most governments restrict the output of readers so that they don't interfere with other RF devices, such as cordless phones.
