Nominal read range is only a shortlist value. Vehicle speed, lane width, reader angle, tag position, nearby tags, barrier timing, interference and controller output determine whether the installation works reliably.
Comparison
Put the decision factors side by side.
Use the table to expose assumptions that should be tested on the selected device and installation.
| Design factor | Project impact | What to validate |
|---|---|---|
| Lane geometry | Controls the read zone and risk of adjacent-lane reads | Reader position, angle and lane separation |
| Tag | Vehicle material and mounting position affect reading | Tag type and consistent placement |
| Range | Maximum range is not always the safest operating range | Required trigger zone on the actual lane |
| Controller | The reader must deliver the accepted credential format | Wiegand, serial or network interface by model |
