Installation is where most RTLS & RFID projects die — or pay back.

Hardware is the line item every procurement team budgets against. Installation is where the project actually lives. The split is consistent across technologies:

UWB anchor: hardware €200-300 · install €1,000-1,500 (RF survey, ceiling mount, PoE, TDoA sync, multipath tuning, commissioning).
RAIN RFID fixed reader / portal: hardware €600-1,500 · install €1,200-2,000 (antenna placement,

cabling, RF-tuned shielding, dock-door geometry, conveyor integration).
RTLS-grade RFID (Zebra ATR7000, RF Controls): hardware €1,500-3,500 · install €1,500-2,500 (ceiling phased-array placement,

beam-steering calibration).
BLE-AoA Locator (Quuppa, Aruba, Cisco BLE-integrated): hardware €400-900 · install €800-1,200 (ceiling grid,

multi-antenna alignment, multipath-aware geometry).
LoRaWAN gateway (private network): hardware €1,000-3,000 · install €1,500-3,000 (rooftop / tower mount,

backhaul, lightning protection, line-of-sight survey).
Active RFID base station / Wi-Fi AP for RTLS: hardware €300-1,500 · install €800-1,500 (often bundled with network refresh).

On a 5,000 m² industrial site needing 40-60 anchors / readers / locators, the install bill alone runs €40,000-€120,000. Multi-site rollouts compound it linearly. Hardware is rarely the deciding cost; install is.

Three structural forces push every vendor's reference design toward more devices than the site actually needs — and the pattern repeats across UWB, BLE-AoA, RAIN RFID and LoRaWAN:

1. Accuracy / coverage buffer. When the vendor commits to 30 cm @ 95th percentile (UWB), sub-metre BLE-AoA, or 99% RAIN read accuracy, their RF engineer adds 20-30% device headroom so the SLA holds in degraded conditions. That headroom is your install bill.

2. SLA lock-in. Over-density makes the accuracy commitment unfalsifiable. If you ever miss the KPI, the vendor adds ‘a few more anchors’ — at full hardware-plus-install price. The original design protected their contract, not your budget.

3. Hardware revenue. Most RTLS / RFID vendors are silicon-and-hardware businesses. Reseller margin on every anchor, reader, Locator or gateway pays the account manager who scoped it. Reference designs trend dense for a reason that's nothing to do with physics.

We've seen 5,000 m² automotive WIP deployments designed for 80 UWB anchors when 40 met the KPI under production load; 18 dock-door RAIN RFID portals on a 12-dock site; BLE-AoA hospitals scoped at 1 Locator per 50 m² when 1 per 90 m² would have hit clinical workflow accuracy.

Half the project budget — gone to RF buffer that did nothing the day after commissioning.

Different projects need different levels of TRACIO involvement. Three engagement models, all of them vendor-neutral, all of them tied to your accuracy KPI rather than to vendor hardware revenue:

A · PMO ownership — we manage the chosen vendor and contracted installer. You buy hardware direct from the chosen vendor on your terms.

We take PMO ownership of the deployment, coordinating between the vendor's RF engineering team, the contracted installer, your IT/OT and operations teams, and the integration partner.

Our job is to keep all four aligned to your KPI and acceptance test — not to the vendor SLA, which is usually weaker. Best when you already have a preferred installer or framework agreement, or where vendor SLA is conditional on their installer doing the work.

B · Independent physical install — we do the cabling and hardware mounting. When the vendor's preferred installer can't be trusted on the KPI commitment,

or you want a clean separation between hardware supply and install responsibility, we install the network and infrastructure ourselves.

PoE switch backbone, CAT6A / fibre cabling, ceiling penetration and tray work, anchor / reader / Locator / gateway mounting at design-verified heights and orientations, synchronisation calibration, multi-time-of-day commissioning under production load.

We do not earn margin on the hardware we install.

C · Vendor-design liaison — we engage the hardware vendor on critical mounting and density. Where you've already committed to vendor + installer but want independent validation of the design before signing,

we work directly with the vendor's RF engineering team on the critical mounting requirements: anchor heights, antenna orientation, RF-blocker mitigation, multipath-tolerant geometry, ceiling-grid alignment, anchor synchronisation strategy.

The output is a design that's been pressure-tested against the as-built environment before installer mobilisation, so the contractor delivers to a target that actually works rather than to a reference design that doesn't survive the live site.

Most general-purpose AV / network contractors are competent at PoE drops and ceiling mounts. They are not RF engineers, and RTLS / RFID accuracy is an RF problem.

Five failure modes account for the majority of post-install accuracy regressions we get called in to fix — and they apply across UWB, BLE-AoA, RAIN RFID and LoRaWAN:

1. Anchor / Locator / reader height drift. A UWB anchor designed for 4.2 m mounted at 3.8 m changes the cone of coverage by 15-25%.

A BLE-AoA Locator at the wrong height destroys angle accuracy. A RAIN RFID portal antenna 200 mm off design height misses tags. The RF model breaks silently.

2. RF blockers introduced post-survey. Site survey ran on an empty bay. By go-live the bay has racking, machine guarding, conveyor cages, mezzanines or temporary tooling that the survey never accounted for.

Multipath and shadowing patterns change. The contractor signs off at commissioning; the system fails six weeks later.

3. Multipath / reflection from metal and glass. Metal racking, glass partitions, stainless hygiene panels (pharma, food), ceiling HVAC ducting and concrete-aggregate floors create UWB and BLE-AoA multipath, RAIN RFID nulls, and LoRaWAN shadowing.

Device placement must compensate via geometric offset, not just count. Most contractors install on the ceiling grid — fast, RF-disastrous.

4. Line-of-sight gaps over the production day. A site survey at 09:00 doesn't see the 11:30 shift change when a 12-tonne press cycle blocks four anchor sightlines, or a dock-door overhead door cycle interrupts RAIN reads, or a forklift mast occludes a BLE-AoA Locator.

We run multi-time-of-day survey passes; most installers run one.

5. Synchronisation and back-end timing. TDoA UWB requires nanosecond synchronisation across anchors. BLE-AoA Locators need precise time-alignment. RAIN RFID readers need consistent power-cycle timing.

LoRaWAN gateways need GPS-disciplined clocks. A subtly mis-cabled PoE switch with hop-count latency variance will quietly destroy positioning accuracy without ever logging a network error.

Whichever engagement model fits, the scope covers the full RF and network infrastructure for the project — not just the visible hardware:

• Predictive RF site survey calibrated against the as-built environment — racking, machinery, glass, HVAC, ceiling height variation, floor materials.
•

Anchor / reader / Locator / gateway placement at design-verified heights with multipath-aware geometric offset across UWB, RAIN, BLE-AoA, LoRaWAN, Wi-Fi RTLS and active RFID.
•

Network design and PoE backbone with VLAN segmentation per IEC 62443, TDoA / sync timing tolerance, and dedicated RTLS traffic class.
• Cabling and physical install — CAT6A, fibre, cable trays, conduit, ceiling penetration, lightning protection for rooftop gateways.
•

Synchronisation calibration — TDoA nanosecond sync, BLE-AoA time-alignment, RAIN power tuning, LoRaWAN GPS lock.
• Multi-time-of-day commissioning under production load — accuracy validated against the KPI in the conditions the system will actually run in.
•

Acceptance test execution against pre-agreed go / no-go criteria measured in production, not in vendor-demo conditions.
•

As-built documentation pack — RF survey data, accuracy validation report, network design, anchor / reader register, photographs, sign-off by operations + IT/OT.
•

Handover to operations with named accountability for drift detection and re-calibration. Optional managed-services tail.

Vendor-design audit (Engagement C): from €8,000-€18,000 per site, depending on complexity. Typical saving on the install bill alone: €20,000-€50,000 single-site, €100,000-€400,000 on multi-site rollouts of 5-15 sites.

PMO ownership (Engagement A): day-rate or fixed-fee against deployment milestones. Typical engagements run 3-6 months single-site, 6-18 months multi-site.

We're accountable to the KPI, not to vendor SLA — so the commercial structure ties our fee to your acceptance test, not to a project schedule.

Independent physical install (Engagement B): priced per device at €900-€1,400 fully loaded — comparable to the vendor's nominated installer,

but with no commercial dependency on hardware revenue and with KPI accountability the typical contractor SOW does not provide. Larger rollouts negotiated against volume.

The defining commercial point: the install bill is where the business case lives. A 60-anchor vendor design at €1,250 / install is €75,000 in install alone.

A 42-anchor TRACIO-audited design at €1,000 / install is €42,000 — €33,000 saved on a single site. On a 12-site automotive WIP rollout, that's €396,000 — typically more than the entire scoping, design and PMO fee combined.

Four deployment patterns we see consistently:

UWB at scale in automotive, aerospace MRO and large industrial WIP tracking. Anchor counts run 40-100 per site; over-spec savings dwarf the audit fee within the first site.

BLE-AoA in hospitals. Vendor designs over-specify Locator density to lock-in clinical workflow accuracy SLAs. We've cut Locator counts by 30-40% on hospital RTLS deployments while exceeding the original accuracy KPI.

RAIN RFID at retail / warehouse scale. Multipath from racking is the dominant constraint; portal antenna geometry, smart-shelf tuning, and dock-door RF management are routinely mis-specified.

Better placement, fewer fixed readers, accuracy holds, item-level inventory accuracy lands at 98%+.

RTLS-grade RFID (ATR7000, RF Controls) on warehouse-scale passive-tag RTLS deployments. Ceiling phased-array placement is unforgiving — most installers have never deployed it before.

Independent install or close PMO control is usually the difference between a working system and an expensive failure.

LoRaWAN private networks across distributed outdoor sites — campus utilities, oil & gas, agriculture. Gateway placement is GPS-line-of-sight critical; contractors often skip the elevation survey. Few enough gateways that the cost of getting placement wrong is enormous per device.

Where the service is less needed: small UWB deployments under 10 anchors, single-room BLE proximity, or pure RAIN handheld-cycle-count operations. The infrastructure budget is too small to justify the audit overhead.
