How Warehouse Tracking Systems Work
from scan event to location estimate.
Warehouse tracking systems convert a physical event into a software record. Barcode records a deliberate scan. Passive RFID detects tagged material crossing a reader field. BLE estimates proximity to gateways. UWB calculates high-accuracy position from timed radio measurements. Computer vision interprets camera feeds. Each method needs a different building layer before the application can work.
Tags, readers, anchors, gateways, and software convert movement into usable location events
SRS Networks is a nationwide IT infrastructure deployment partner headquartered in South San Francisco, California, serving multi-site enterprises across 48 states since 1996. This page turns field-delivery requirements into a scope, comparison, and acceptance record a buyer can use.
Tracking methods compared
| Method | How it detects | Building requirement |
|---|---|---|
| Barcode | Person scans a printed code | Reliable WiFi, scanners, printers, and charging |
| Passive RFID | Reader energizes and detects a tag | Portals, antennas, conduit, PoE, and RF tuning |
| BLE | Battery tag broadcasts to nearby gateways | Gateway density, mounting, power, and backhaul |
| UWB | Anchors measure signal timing | Anchor geometry, sync, PoE, and calibration |
| Computer vision | Software interprets camera images | Views, lighting, bandwidth, compute, and retention |
Accuracy changes the infrastructure
Knowing that an item crossed dock door 12 is different from locating it within a meter. Do not buy anchor density for precision the operation will never use.
Tags drive operating cost
Passive, battery, reusable, disposable, metal-mount, and temperature-rated tags have different workflows. Tag handling belongs in the pilot, not only the software demo.
The pilot must use real material
Validate metals, liquids, pallet density, forklift speed, door geometry, and neighboring radios. Bench demonstrations remove the physical conditions that cause field misses.
When this is not the right approach
SRS does not recommend a software brand or sell tracking hardware. We explain and deploy the building infrastructure after the operational use case and platform are selected.
