Survey & design engineering
Buy the design. The install is optional.
RF surveys, predictive design and bid-ready drawings for Wi-Fi, DAS and ERCES, whether WZC installs it or not.

How it works
Measure first, then design
We walk the building and measure every grid cell, then design antenna placement so the weak cells come up to strength.
How it works
From walk-through to drawing set
Scope
What the building is, what it has to carry, and which of the four packages fits. Half an hour, usually.
Survey & grid test
The building is measured: benchmark grid test for ERCES, passive or AP-on-a-stick survey for Wi-Fi.
Model
Predictive design in iBwave or Ekahau, engineered to a target with margin rather than to a minimum.
Validate
The model is checked against the measurements, and against the radio actually proposed.
Hand over
Drawings, heatmaps, BOM, cabling schedule and the validation report. Yours to build from, or to put out to bid.
The front end is the product
Measure first, then draw, then build
Most wireless goes wrong before anyone mounts anything. A system designed from a floor plan and a hopeful assumption meets the building on installation day, and the difference is paid for in change orders, in rework and in a failed inspection nobody budgeted for.
We sell that front end on its own. Architects, general contractors and other integrators buy WZC design packages for buildings we will never install, because the drawing is the deliverable, and a drawing that has been measured against the real building is worth more than one that has not.
- Benchmark grid testing to IFC 510 and NFPA 1225
- Predictive modeling in iBwave and Ekahau
- AP-on-a-stick validation before anything is bought
- Bid-ready drawings, BOM and cabling schedule
Four ways in
Design packages that stand on their own
Deliverables: coverage and capacity heatmaps, AP placement drawings, cabling schedule, BOM, and a validation report your integrator or ours can build from.
Fixed fee, quoted after the scoping call, and credited in full if WZC builds the project.
Predictive design
For greenfield sites: modeled from the drawings, with bid-ready AP placement, a BOM and a cabling schedule.
AP-on-a-stick survey
For vendor changes and high-stakes spaces: the proposed access point is tested in place before anything is purchased.
Hybrid survey
For occupied buildings: a passive survey of the network you have, plus a predictive design for the refresh.
ERCES design package
For owners whose GC or electrical contractor will install: the benchmark grid test, the iBwave design, and the AHJ submittal set.

Measured, not assumed
A benchmark grid test or RF survey establishes where the building actually stands before a line is drawn.
Modeled with margin
iBwave and Ekahau models designed to a target, with headroom for the walls and the people the model cannot see.
Proven on site
AP-on-a-stick testing puts the proposed radio in the real space, so the model is checked before the purchase order.
Bid-ready drawings
Placement, pathways, BOM and schedule, in a package your AHJ, GC and IT team can all build from.
Survey and design, answered
Can you do just the survey and design?
Yes. It is a scoped, fixed-fee engagement and a large part of what this team does. Architects, GCs and other integrators buy WZC design packages for buildings we will never install.
What is an AP-on-a-stick survey, and when do we need one?
The access point you are proposing is mounted temporarily in the real space and measured where it will actually live. It is worth doing when the vendor is changing, when the space is unusual (atria, warehousing, stone and glass) or when the purchase is large enough that being wrong is expensive.
We are standardized on another vendor. Can you still design it?
Yes. The design is engineered around your building and your standard, not around a product we prefer to sell. Confirm the platform with us and the model is built on it.
Do you charge for the survey, and is it credited?
It is a paid, scoped deliverable, because it is the engineering the rest of the project depends on. Where WZC goes on to do the build, the fee is credited in full toward the project.
How do you handle a building that needs Wi-Fi, cellular and ERCES?
As one RF plan rather than three. The three systems share pathways and headend space, and designing them together is the whole reason they fit.
What do we actually receive?
Coverage and capacity heatmaps, AP placement drawings, a cabling schedule, a BOM, and a validation report your integrator or ours can build from.
