RFID Site Survey Guide
An RFID site survey records the intended business event, item path, nearby tagged inventory, structures, RF sources, power, network, mounting, environmental and safety constraints before final design.
Key takeaways
- Survey the process and the physical site together.
- Nearby tagged stock is a key false-read risk.
- Cable, power and service access can constrain antenna placement.
- Document photos and dimensions with access approval.
How to evaluate this decision
Walk the actual item path with operations staff. Mark stops, reversals, congestion, door states, adjacent storage and expected exceptions.
Inspect metal, glass, liquids, conveyors, vehicles, existing radios, network coverage, grounding and mounting. Record what can change between shifts or seasons.
Decision factors
| Factor | What to verify |
|---|---|
| Workflow | Item path, users, direction, speed, triggers and exceptions. |
| RF environment | Structures, tagged stock, neighboring readers and interference sources. |
| Infrastructure | Power, network, cable routes, cabinets, sensors and integration points. |
| Compliance/safety | Regional radio, electrical, mechanical, access and privacy constraints. |
Practical selection and validation checklist
- Use a standardized survey worksheet.
- Measure and photograph approved areas.
- Run temporary RF tests with representative items.
- Review assumptions with site owners before design freeze.
Limitations and project boundaries
- A survey is a time-specific snapshot.
- Temporary tests may not represent peak inventory or traffic.
- Local safety and regulatory review cannot be replaced by a website checklist.
Frequently asked questions
Is an RF spectrum analyzer always required?
Not always, but RF observation can help when interference or coexistence is a risk.
Who should attend?
Operations, facilities, IT/integration and the RFID engineer, with safety or compliance roles as needed.
Can a remote survey replace a visit?
Photos and drawings help early design, but higher-risk zones usually need on-site validation.
