Exact floor position only where the mark matters
Exact floor position is a third accuracy band, not the default logistics buy. Do not treat every no-go zone as a sub-meter job.
What exact floor position is
Exact floor position means the reported location is on the mark, not merely near it. In plant terms that is usually sub-meter (~3 ft), often about 10–30 cm (4–12 in) where line of sight holds. The jobs that need it are dock-face confirmation, a tight safety cell, proof that the vehicle is inside a named slot, or any rule where a reading that is only nearby would trigger the wrong action. Industry indoor-positioning cost guides treat that band as a real jump in anchors, cabling, and calibration per square metre (per square foot).
It is not zone presence, which only answers which wing, which large hall section, or which gate the asset is in. It is also not medium-precision location around 1–3 m (3–10 ft), the band that already settles most aisle, buffer, bay, and fleet-load calls. How those first two bands differ is covered in zone presence vs medium-precision logistics track. Radio families that can deliver the tight band, such as UWB or AoA on BLE, are compared in compare RTLS technologies.
Exact floor position is not every no-go zone
A no-go zone is a restricted polygon with a rule. It is not by itself a sub-meter requirement. Many no-go zones already work at medium precision when aisle-scale presence is enough: keep trucks out of a pedestrian lane, keep visitors out of a large maintenance bay, flag entry into a named corridor. The decision is whether the asset is inside the named area, not whether it sits on a 20 cm (about 8 in) paint line. Industry RTLS practice makes the same split. Broad restricted areas can run as presence or medium-precision events. Narrow boundaries next to adjacent workstations, or cells where near the mark is wrong, need the tighter band.
Conflating no-go with exact floor position is how quotes inflate. A plant that only needs aisle-scale exclusion gets priced as if every polygon were a dock-face proof. For each zone, write the accuracy you need in metres (feet) before you name a radio. Keep medium-precision no-go zones on the fleet grid. Reserve exact floor position for the marks that fail when the reading is only nearby.
Where the tight band earns its keep
Put the high-precision infrastructure on the mark, not across the whole roof. A 100,000 m² (about 1.08 million ft²) building and a small hall use the same rule. On a large roof, fleet work still sits on a shared medium-precision grid, detailed in one large building and a large fleet. On a small hall, the same aisle decisions still sit on inverted BLE, detailed in small fleet in a small hall. The tight zone is a few bays, a dock face, or a safety cell in either place.
A documented 55,000 m² (about 592,000 ft²) white-goods plant invested €50,000 (about $55,000) in logistics real-time location system (RTLS) and brought average forklift speed from 15 km/h (about 9 mph) to 6 km/h (about 4 mph) while performance held. That result did not need a hall-wide sub-meter grid. Medium-precision path evidence was enough for the speed and compliance review. See slower forklifts with the same performance for that case.
Why a hall-wide exact-position grid misses ROI within six months
Infrastructure cost rises when the accuracy band tightens. Vendor and industry guides often show UWB or dense high-precision layouts needing far more anchors and higher per-square-metre (per-square-foot) spend than a medium-precision logistics track. On a large roof those anchors multiply with area. The aisle and fleet decisions that pay the project back still only need about 1–3 m (3–10 ft). The extra centimetres (inches) never change which truck is free, the empty travel cut, or how many trucks the hall keeps.
A small exact-position zone can still earn ROI within six months, because its area is the mark, not the hall. A full-hall exact-position quote that cannot name those marks usually fails the six-month test on a large building. How to judge that return by combination is covered in the six-month return depends on the combination. Hidden install line items are listed in what to include when calculating RTLS ROI.
One dataset, three equal uses
Medium-precision and exact-floor-position readings can share one map and one spatially oriented dataset. Live internal logistics and industrial fleet management use medium-precision locations for search, load, and aisle heat. The same place-and-time record feeds continuous improvement. Correlation and causality analytics can then ask whether a miss on a dock mark, or an empty corridor, kept preceding a line stop. Those three jobs carry equal weight on the digital twin. Correlation work is not a footnote to logistics.
Product work for the live hall sits under internal logistics optimization and production monitoring. Capability depth is on the features overview.
How teams keep precision on the decision
1. Write each decision in metres (feet) before you name a radio - Aisle waste and most no-go zones are about 1–3 m (3–10 ft). A mark that fails when the reading is nearby is tighter.
2. Price exact floor position only for the bays that need it - Leave the rest of the roof on the medium-precision fleet combination.
3. Reject a hall-wide exact-position quote that cannot name the marks - Area times the dense band will not pay back within six months when the fleet never uses those centimetres (inches).
4. Keep documented medium-precision cases as evidence - Do not add centimetres (inches) to make a vendor presentation look stricter when aisle-scale location already settled the job.
How a rollout is priced is on pricing. Start the radio choice from the decision in start with the decision, not the technology.
