DAS Coverage Survey
Find your building's cellular dead zones before you pay for a DAS design — a fixed-fee, carrier-grade coverage assessment with a sized remediation budget if gaps are found.
Design retainers are priced against an assumption. This replaces the assumption with data.
A DAS design proposal has to assume how bad your coverage problem is before anyone's measured it. Guess wrong and you either overpay for a system your building doesn't need, or under-spec one that fails carrier acceptance after it's installed — the most expensive way to find out you needed more antennas.
Our coverage survey replaces the guess with a signal-level heatmap and a sized budget, for a fixed fee, before you commission any design work.
What's included in every survey
Every engagement produces the same deliverable set, sized to your building.
Floor-plan review + georeferencing
Pre-walk review of your floor plans with grid georeferencing to plan sample points before we're on-site.
Predictive + walk-test assessment
Blended predictive modeling and on-site RF coverage measurement, scaled to building size and complexity.
Carrier signal-level benchmarking
RSSI, RSRP, and SINR measurements benchmarked against carrier-acceptable thresholds.
Coverage heatmap per carrier band
PNG + PDF heatmap for every carrier band surveyed, floor by floor.
Coverage gap analysis
Pass/fail verdict against carrier thresholds, with dead zones identified and quantified.
Indicative design + budget
If gaps are found: a sized DAS design concept and budget range — enough to make a go/no-go call.
Head-end / antenna placement
Preliminary recommendations for head-end location and antenna placement to close identified gaps.
30-min review call
Debrief with ownership or facilities to walk through findings and next steps.
Fixed-fee, scoped to your building
Every survey is quoted as a flat, one-time fee — no duration commitment, no hourly billing. Your price depends on two things: building size and complexity (see below). Tell us the address and square footage and we'll come back with a fixed number in one business day.
Which complexity tier is your building?
Complexity is the second factor in your quote, alongside building size. Pick the closest match — the scoping call confirms it.
Low complexity
Open warehouse or single-floor building, single carrier band of interest, straightforward RF path, no unusual construction materials (low-E glass, metal decking) blocking signal.
Medium complexity
Mixed-use building, 2–5 floors, standard carrier mix, typical commercial construction. Most office, retail, and light-industrial buildings land here.
High complexity
Hospital or high-rise, cold storage or heavy-shielding construction, multi-carrier requirement, campus/multi-building scope, or below-grade parking and basement levels.
Add-ons
Available à la carte and layered on top of the base survey — ask about these during your scoping call.
After-Hours
Nights, weekends, or off-hours scheduling to avoid tenant disruption.
Additional Carrier Band
Each carrier band surveyed beyond the first (e.g. AT&T + Verizon + T-Mobile).
HazLoc
Hazardous-location / explosion-proof environments requiring specialized procedures.
Expedited Report
Survey report delivered within 3 business days.
Re-Survey
Return visit if building or tenant layout changes materially before design starts.
How we benchmark coverage
Commercial DAS surveys aren't governed by a single code the way public-safety ERCES is — we benchmark against carrier RF acceptance criteria and standard industry measurement practice.
Carrier RF acceptance criteria
AT&T, Verizon, and T-Mobile each publish minimum in-building signal-level thresholds a DAS must meet before they'll connect to it. We benchmark against these so the survey verdict matches what a carrier will actually accept.
iBwave predictive modeling
Industry-standard RF prediction software models likely coverage before we're on-site, so field time is spent confirming and refining rather than blind-sampling an entire building.
3GPP signal measurements
RSSI, RSRP, and SINR — the standard cellular signal-quality measurements defined for LTE/5G — recorded at every sample point, not just a bar-count on a phone.
Gap-to-budget methodology
Where coverage falls short, we translate the gap directly into an indicative antenna count, head-end sizing, and budget range — not just a map of red zones.
Frequently asked questions
Written for facilities leads, property managers, and developers evaluating DAS coverage before committing to a design.
Why survey coverage before designing a DAS?
A design retainer is priced against an assumed scope. If the real dead zones are worse or better than assumed, you either overpay for a system you don't need or under-spec one that fails carrier acceptance. The survey replaces the guess with an actual coverage heatmap and a sized budget before you commit to a design fee.
Is this a walk test or a predictive survey?
Both, blended by building size and complexity. Every survey starts with predictive modeling to identify likely dead zones, then we confirm with on-site RSSI/RSRP/SINR measurements at representative points on every floor. Larger or more complex buildings get denser on-site sampling.
How many carrier bands does the base price cover?
Base pricing covers a single carrier band. Most buildings need coverage from more than one carrier, so add the Additional Carrier Band add-on for a full multi-carrier assessment — ask about pricing during your scoping call.
What happens if the survey finds a coverage gap?
You get a coverage heatmap showing exactly where signal falls below carrier-acceptable thresholds, plus an indicative DAS design and budget scoped to close the gap. That indicative budget isn't a sealed design — it's enough to make a go/no-go decision before you commission full engineering.
How is this different from a post-install DAS acceptance test?
This survey happens before a DAS exists, to inform whether and how to build one. A post-install acceptance test verifies that a completed DAS actually meets carrier signal-level requirements once it's live — a separate, later engagement with its own scope.
