The cost of a UWB real-time location system (RTLS) depends mainly on the area you cover, the number of tags and the work needed to install and integrate it, so the fairest way to compare offers is the total cost of ownership per square metre over five years.
The price of a tag or a base station (UWB anchor) on its own says little: a cheaper base station that covers half the area doubles the cabling. This guide lists what you pay for, works through an example budget, and shows how to build and prove the return on investment.
What do you pay for in an RTLS?
In its simplest form, TCO is hardware plus installation plus software. In practice it helps to split it further, because each line has a different driver:
| Cost item | One-off or recurring | What drives it |
|---|---|---|
| Base stations | One-off | Area, environment and coverage per base station |
| Tags, badges and chargers | One-off, plus replacements | Number of people, vehicles and assets; tag type |
| Network | One-off | PoE switches and cabling; how much existing network can be reused |
| Installation and calibration | One-off | Number of base stations, mounting height, access, calibration method |
| Software | Subscription or one-off licence | Area, tags or sites; cloud or on-premise hosting |
| Integration | Mostly one-off | Systems to connect (WMS, MES, ERP) and workflows to automate |
| Project management and training | One-off | Number of sites, users and use cases |
| Support and maintenance | Recurring | Service level, spares, batteries, updates |
Do not forget your own time: IT, operations, safety and, if people wear tags, employee consultation. It is rarely in the vendor’s quote.
Why does coverage per base station matter so much?
Base stations drive more than their own price. Each one needs a cable run, a mounting point, a place in the network and a calibrated position. The number of base stations depends on how much area each one can serve, which depends on the positioning method and the environment.
A 10,000 m² hall planned at 200 m² per base station needs 50 base stations; at 400 m² per base station it needs 25. Every base station that is not needed also removes a cable run, a mounting point and a calibration step. The calibration method matters for the same reason: surveying each base station by hand costs time per base station, while automatic calibration costs about the same whatever the count.
What does an example budget look like?
The example below is a 10,000 m² warehouse with 50 base stations, 300 tags on forklifts, carts and pallets, one integration with the warehouse management system (WMS), and a five-year horizon.
| Item | Illustrative calculation | One-off | Per year |
|---|---|---|---|
| Base stations | 50 × €600 | €30,000 | – |
| Tags | 300 × €60 | €18,000 | – |
| Network (PoE switches) | Lump sum | €4,000 | – |
| Installation and calibration | 50 × €400 | €20,000 | – |
| Integration with the WMS | Lump sum | €25,000 | – |
| Project management and training | Lump sum | €8,000 | – |
| Software subscription | Lump sum | – | €12,000 |
| Support, spares and batteries | Lump sum | – | €5,000 |
| Total | €105,000 | €17,000 |
The five-year TCO is €105,000 + 5 × €17,000 = €190,000. That is €19 per m² over five years, or €3.80 per m² per year. If each base station covered twice the area, 25 fewer base stations and installations would save 25 × (€600 + €400) = €25,000, about 13 % of the five-year TCO.
Where does the return come from?
Most RTLS business cases rest on a few levers. Put a number on each one that applies to you, using your own wages, volumes and shift patterns.
| Lever | What to measure | Illustrative value per year |
|---|---|---|
| Search time | Minutes per shift spent looking for pallets, carts or tools | 20 drivers × 15 min × 2 shifts × 230 days × €40/h = €92,000; halving it saves €46,000 |
| Vehicle utilisation | Hours each forklift drives loaded, empty or stands idle | Retiring 2 of 25 trucks at €10,000 each saves €20,000 |
| Safety | Near misses, incidents and lost days | Hard to forecast for one site; treat as risk reduction |
| Quality and FIFO | FIFO breaks, misplaced or expired material, scrapped work in progress | Depends on the value of the goods |
| Paperless bookings | Manual scans replaced by zone events | Time per booking × bookings per year |
In the example, €46,000 + €20,000 = €66,000 a year in benefits, minus €17,000 a year in running costs, leaves €49,000 a year. The €105,000 one-off cost therefore pays back in a little over two years. Over five years, €330,000 of benefits against a €190,000 TCO gives a return of about 74 %.
Safety deserves a separate line. Workplace injuries and new cases of work-related ill health cost Britain around £22.9 billion in 2023/24 according to the HSE, and EU-OSHA estimates that work-related accidents and illnesses cost the EU at least €476 billion a year. Those totals show the stakes, but they do not predict savings at one site, so keep safety benefits apart from the hard savings.
How do you run a pilot that proves the ROI?
- Pick one area and one or two use cases with a number attached, such as search time or empty driving.
- Measure the baseline first, with time studies, logs or a sample of shifts over two to four weeks.
- Agree success criteria in writing: accuracy per zone, availability, and the target change in each measure.
- Install in a representative area, including its most difficult corner, not only the easiest hall.
- Run for four to eight weeks with the people who will use the system, and connect at least one real workflow.
- Compare with the baseline, update the TCO model with real figures, and decide on the rollout.
If people wear tags, the employee consultation and data protection impact assessment belong in the pilot, not after it. To lower cost in the rollout, reuse existing PoE switches and cable trays, choose the lowest update rate each use case allows, and phase the rollout so that the areas with the clearest return come first.
Where to go next
To turn your floor plan into a base-station count, read planning a UWB RTLS deployment and try the base station estimator. The case studies show what customers track and why, and you can ask for a budget estimate for your site.
