Active, passive, and hybrid distributed antenna systems designed against measured RF — not vendor coverage charts.
Distributed antenna systems extend public carrier or private cellular coverage into buildings that block, attenuate, or shadow it. Hospitals, stadiums, manufacturing plants, parking decks, and high-rises all have structures that defeat off-air signal. We design DAS systems based on what the building actually does to RF, then run the carrier coordination so the system can be commissioned cleanly.
We start with the architectural drawings, occupancy class, and any fire/ERRCS code obligations. The design constraints differ for a hospital and a warehouse — we want to know which one we're in.
We measure existing carrier and first-responder signal inside the structure with calibrated test gear. Predictive software alone has been wrong often enough that we don't trust it on its own.
Off-air, small-cell, or BTS source. We model link budget end to end and size the active equipment against the worst-case carrier.
We run the engineering submission process with each carrier on the system. This is where DAS projects most often stall — we treat it as part of the deliverable, not a hand-off.
We run the IFC-compliant grid test, document signal levels, and produce the binder the AHJ wants to see.
A wireless assessment from DigiLux puts measured RF, an operations brief, and a vendor-neutral design on the table — usually in under five weeks.
