The problem
Low-E glass, spray foam insulation, concrete tilt-wall, steel decking and metal racking each cost you 20–40 dB of signal at the envelope. Carriers design their macro networks for outdoor coverage — what happens past your exterior wall is your problem to solve.
Typical envelope loss by material
Missed calls
Sales, dispatch and service calls dropping the moment staff walk inside.
Wi-Fi calling gaps
Wi-Fi calling fails on handoff and never covers docks, yards or stairwells.
Code exposure
Failed public-safety radio testing blocks your certificate of occupancy.
Ops downtime
Barcode scanners, tablets and IoT sensors on LTE go offline.
That is what a properly engineered in-building system does — it takes the outdoor signal you already pay for and distributes it past the envelope.
Systems we build
A rooftop donor antenna feeds an FCC-certified bi-directional amplifier that redistributes every carrier through a coax network of ceiling domes and panel antennas. No carrier base station, no monthly fees, no recurring backhaul.
Separate 700/800 MHz emergency responder system engineered to NFPA 72 and IFC 510: NEMA 4 enclosure, 12/24-hour battery backup, annunciator panel, AHJ grid testing and annual recertification.
Fiber-fed remote units for campuses, and hybrid active/passive topologies where a single donor location has to serve multiple structures, parking decks and below-grade levels without stacking noise.

RF Site Survey
We benchmark outside RSRP/SINR per carrier on the roof and walk the interior with calibrated scanners to map every dead zone.
Engineered Design
iBwave-style layouts, antenna placement, cable schedule, link budget and a coverage heat map delivered with a fixed-price quote.
Carrier Consent
Where Part 20 requires it, we file and manage consent with AT&T, Verizon, T-Mobile, Dish and FirstNet on your behalf.
Installation
Licensed low-voltage crews, plenum-rated cabling, lift work, after-hours scheduling and full coordination with your GC or facilities team.
Commissioning
Gain balancing, oscillation checks, uplink noise verification and a walk-test report with before/after heat maps for every floor.
Support & Warranty
Remote monitoring, annual ERRCS recertification, 2-year hardware warranty and a 90-day performance guarantee.
Off-air boosters amplify existing outside signal — the free survey confirms your rooftop benchmark supports one before anything is quoted.
Deployments
LogisticsChicago, IL
Before
-118 dBm at dock doors
After
-72 dBm building-wide
Scanner drop-offs at the dock lines were costing two hours of throughput per shift. A 4-zone passive DAS with 38 interior antennas closed every gap including the yard canopy.
HealthcareHouston, TX
Before
No service below grade
After
Full 5-bar all carriers
Lead-lined imaging suites and a concrete core killed coverage. Dual-system deployment paired commercial carriers with an IFC 510 ERRCS that passed AHJ grid testing first attempt.
HospitalityDenver, CO
Before
1.9 guest signal rating
After
Zero coverage complaints
Low-E glass blocked the tower. Riser-fed design covered all room stacks, ballrooms and the parking structure over eleven overnight install shifts with no guest disruption.

“Our pickers were walking to the office to make calls. Six weeks after the survey we had full bars on every aisle. The heat maps they delivered made the capital request approve itself.”
“They handled the ERRCS and the carrier system as one scope. Our AHJ signed off first inspection — that alone saved our occupancy date.”

Answers
A commercial booster (BDA) is an off-air, carrier-agnostic amplifier system: one donor antenna feeds an amplifier that redistributes all carriers through interior antennas. A traditional DAS is fed by a carrier base station or small cell and requires carrier participation, longer timelines and far higher budgets. For 90% of buildings under 500,000 sq ft, an FCC-certified passive DAS booster system delivers the same in-building experience at roughly a tenth of the cost.
Installed commercial systems typically run $1.50–$3.00 per square foot depending on ceiling height, construction materials, number of carriers required and how much conduit and plenum-rated cabling the building needs. A 50,000 sq ft warehouse usually lands between $45,000 and $90,000 turnkey. Small multi-tenant offices under 15,000 sq ft often finish under $25,000.
Consumer boosters require simple carrier registration. Industrial-grade Part 20 systems above certain power levels require carrier consent, which we handle as part of the engagement — including the paperwork with AT&T, Verizon, T-Mobile and FirstNet.
Cellular boosters do not satisfy fire code. NFPA 72 and IFC Section 510 require a separate public safety ERRCS/BDA on the 700/800 MHz band, with NEMA 4 enclosures, battery backup and annual testing. We design and install both systems together so one contractor owns the entire RF scope.
Survey to sign-off is typically 3–6 weeks. Site survey and RF benchmark takes one day, engineered design and quote 3–5 business days, procurement 1–2 weeks and installation 2–10 days depending on square footage and after-hours restrictions.
An off-air booster amplifies existing outside signal — it cannot create it. If the rooftop benchmark is below roughly -110 dBm RSRP, we recommend a small cell, fiber-fed DAS or a carrier-provided solution instead. Our free survey tells you which category your building is in before you spend a dollar.
