How Warehouse Tracking Systems Work
from scan event to location estimate.
Warehouse tracking systems turn observations into software records. Barcode captures scans; passive RFID detects energized tags; BLE can estimate proximity from signal strength or position using angle-of-arrival locators; UWB uses radio measurements for positioning. Readers or locators pass observations through the selected network to a positioning engine and application. Device models determine power, backhaul, and calibration requirements.
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 the 48 contiguous states, Alaska, and Hawaii 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 | Tag signals support RSSI proximity or angle-of-arrival positioning | Gateway or locator placement, orientation, power, and selected backhaul |
| UWB | Anchors measure signal timing | Approved geometry, synchronization, and model-specific power/backhaul |
| 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.
Primary technical references
Use the current project specification, adopted code, approved design, and manufacturer instructions for the final decision. These primary references explain the testing and planning basis used in this resource.
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.
