Vehicle access RFID simulator with the EM300H
Put an EM300H on a pole at a gatehouse and drive a car or a truck up to the barrier with a tag behind its windshield. See how often each vehicle is read, and whether the next one in the queue or in the next lane is read too.

What this simulator calculates
It estimates how often an EM300H on a pole at a gatehouse reads the RAIN RFID tag behind the windshield of a car or a truck driving up to the barrier, through the glass, with its two built-in antennas (horizontal and vertical). It also counts the stray reads of the next vehicle in the queue and of a vehicle in the next lane.
What you can set
- The vehicle (car or truck), its windshield (laminated, athermic or with metallized film), the tag height and the tag turned on the glass (0 to 90 degrees).
- The speed of the vehicle (5 to 30 km/h) and the place of the pole: height, distance from the lane, position along it, turn and tilt.
- The power of each built-in antenna (H and V), the RSSI filter, Impinj Gen2X and the vehicles that must not be read.
What you see
- The tags a typical pass reads, and the read failures as a count of tags over the simulated passes.
- The same setup with Impinj Gen2X on and off, side by side.
- A 3D view of the pass: the lobe of each antenna, the zone where a tag is read in at least 90% of the tries, and the chance of a read per tag.
- Notes on the setup, such as the EIRP of each antenna against the local limit you type in.
- Stray reads: how often goods that must not be read (beside the reader, the next load, a neighbour) are read, with an alert and how to reduce them.
Questions about the simulator
Is the simulator free? Do I need to install anything?
It is free and runs in the browser, with no sign-up and nothing to install. It needs JavaScript and a browser with WebGL for the 3D view.
Does the result replace a test on site?
No. It is an estimate from a propagation model, the antenna patterns and premises from the literature. Use it to compare setups and prepare the project, then confirm with a pilot on site, with the real tags and products. Identix can help you plan that test.
Who is it for?
For system integrators, meaning any company that builds its own solution, in full or in part: software companies that use Identix readers, makers of their own portals or reading cabinets who buy only antennas or readers, and also installers and end users who are planning a project.
Why does the glass matter?
The tag is behind the windshield. A laminated windshield takes a few dB; an athermic (metal coated) windshield or a metallized film takes far more and the tag must go in the uncoated area. The simulator uses conservative premises from published measurements; confirm with a test at the gate.
