DAS & in-building coverage engagement.
A large urban teaching hospital with multiple connected buildings and a 1990s east-wing addition that had never had reliable public-carrier coverage.
Staff and patients had complained about dropped calls in the east wing for years. Three previous DAS proposals had all recommended similar architectures and similar capex — and all three had been rejected on cost. Clinical engineering had stopped engaging. A change in nurse-staffing model that increased reliance on personal devices for clinical communication brought the issue back to the executive sponsor's desk.
We re-walked the building rather than starting from the prior consultants' reports. The measurement walk identified three previously unrecognized RF absorbers — an addition-era lead shielding in radiology that didn't show on drawings, a copper-mesh interior wall in an interventional suite, and a stairwell concrete pour denser than spec. We redesigned around those features rather than fighting them, and reduced antenna count by a third in the process. We ran carrier engineering submissions for the three relevant national carriers, achieved approval on first submission for two and second for the third, and produced an AHJ-ready commissioning binder.
In-building dropped calls in the east wing fell from a measured baseline of ~14% to under 1% across all three carriers. The system was commissioned $1.8M under the lowest prior bid because the antenna count and head-end sizing were appropriate to the redesigned RF environment.
