  1. RFID Portal Test Rfscl Laboratory UNL

  2. RFID portal test introduction develop warehouse management . tracked more accurately through the portal dock door in real time . improve performance of antennas and increase effective read rate under specific conditions.

  3. Overview • Two experiments • Effectiveness and readability test: Search for reliable test data on the effectiveness in reading RFID tags under different practical usage conditions. • Full read rate experiment: Figure out qualified conditions and specifications for when a customer wants 100% readability.

  4. Objective • Experiment 1: Antennae position Tag placement Read range Antenna selection • Key point: Figure out which factors influence the readability of the antennae.

  5. Experiment 2: Accuracy Readability Distance Key point: Optimum position of tags, antennas, and portal. Recommendations of improving RFID performance

  6. Test description • Exam the performance of RFID system. Yield Variance • Label types • Label placement • Antenna distance

  7. Experiment necessities • Alien Squiggle

  8. Experiment necessities • Matrics Antenna

  9. Experiment design • Experiment 1: • Tag placement: Top, Front, Side • Number of items: One item, three items, six items, ten items • Number of Antennae: One antenna and two antennas (on each side of portal) * Two antenna were only used in one trial within the experiment

  10. Experiment design • Experiment 2: • Tag placement: Tags put on every item on up, side and front. • position of antennas: The same height on each side / The different height (3 ft, 5 ft) on each side • The distance between each side of portal:5 ft / 7 ft

  11. Experiment results and analysis FRONT TOP SIDE

  12. Premium performance is tags on side .

  13. 1 Antenna V.S 2 Antenna • 80% V.S 100%

  14. Tag’s quantity (Only in experiment 1) • The larger the quantity of items was, the poorer the readability of the antenna would be .

  15. Antenna’s position (Only in experiment 2) • Placed in different horizontal line have positive affect on readability. • Portal dock’s position (Only in experiment 2) • The shorter the distance is, the better read efficiency would be.

  16. Conclusion • full-read expectation under these under the specification : • Distance between each side of portal: 6-8 feet. (Experiment 2) • Tag placement: on side.

  17. The reading rate and premium reading scale • specification of 10 tags per pallet • between 2-3 feet around the middle line • reading rate : 90% or more *Frequency, distances and angles, type of tag, location and replacement, influences of moisture and metals, and pallet patterns all played a part in readability.

  18. Recommendations and summary • The 100% readability standard could be tough to meet, but some requirements still could be applied to satisfy the customer’s specific needs. • Total conditions for receiving more than 90% readability
