UWB anchor placement: what to check before you signPoor UWB anchor placement quietly kills accuracy.
UWB is usually the most precise of these options. The accuracy you get depends on your site, and we confirm it in the survey. Here is what matters and what to watch for in any UWB layout.
Why anchor counts get inflated, and what to watch for.
Extra anchors are an easy buffer for a supplier's accuracy commitment, and every anchor is hardware revenue. Once a design is signed, density is hard to challenge: if the system misses its target, more anchors get added at full price.
Ask the supplier which anchors your KPI depends on, and which are padding.
The five things that decide a UWB layout.
Spacing, mounting height and the number of anchors each zone needs depend on your racking, ceiling and traffic. Rules of thumb are a starting point for a survey, not a substitute for one. We check your layout against your site in a design review.

What a design review gives you.
A predictive RF model against your building as it stands, a justification for every device, a mount-point register and an acceptance test plan. Scoped per project: see our infrastructure and install service and our fees.
Frequently asked questions
How many UWB anchors do I actually need?
It depends on your racking, ceiling, traffic and the accuracy each zone needs. We work it out with you in the survey, against your own KPI.
Does this guide apply to all UWB suppliers?
Yes. The physics of UWB anchor placement is the same for every supplier. The differences are in reference design assumptions and service commitments.
Can we review a layout without an independent consultant?
If you have an in-house RF engineer with UWB experience, yes. If not, a free 30-minute call is a quick way to find out what to check first.
What is the most common anchor placement mistake?
Mounting anchors on the ceiling grid for speed, instead of placing them for the geometry each zone needs.
