TunnelView RFID simulator
Push a tagged pallet or roll container through the TunnelView, in one side and out the other, in a tunnel of 2, 4 or 6 m with a curtain at each end. See how often every box is read, and whether the pallets waiting at the ends are read too.

What this simulator calculates
It estimates how many RAIN RFID tags the TunnelView reads on a pallet or roll container pushed through it by hand, in one side and out the other, pass after pass. The tunnel is the PalletView in 2 m modules without the back, with a metallized curtain at the entry and at the exit; the steel walls, the curtains and the reflections inside are conservative premises.
What you can set
- Reader: EZ700, EZ500 or EM300, with Impinj Gen2X on or off.
- Four antennas on the side walls of the middle module (85C7070, 65C6095, 90C4090 or 85DL4090), their height, power, cable loss and RSSI filter.
- The tunnel length (2, 4 or 6 m), the walking speed and the curtains down or up.
- The load: boxes on a pallet with box tags or item-level tags and the product inside, or a roll container.
- The next pallet waiting before the entry and the one just checked after the exit (stray reads).
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.
Is a longer tunnel better?
A longer tunnel keeps the curtains and the pallets waiting at the ends farther from the antennas, so it reads fewer of them by mistake; the load is read in the same middle module. Compare 2, 4 and 6 m in the simulator with the pallets waiting at both ends turned on.
What is a stray read and how do I reduce it?
A read of a tag that is not on the load going through: the next pallet waiting before the entry or the one just checked after the exit. Turn them on in the simulator to see how often they are read, with the curtains down and up and with each tunnel length. Keeping both curtains down, a longer tunnel, more room before the entry, recording only while a presence sensor sees the load inside and the RSSI filter reduce it.
