In-Building Wireless

Cellular DAS.

Eliminate dead zones with carrier-grade in-building coverage.

The WZC approach

Every floor. Every carrier.

Dropped calls and cellular dead zones cost productivity and frustrate occupants. WZC engineers in-building cellular that covers every floor and every carrier.

We deploy Nextivity (Cel-Fi), SOLiD, and Corning systems sized to your building and carrier mix.

What you get

Built to perform

Multi-carrier coverage

Carrier-agnostic systems for full-building reach.

BDA & booster systems

Right-sized amplification for your floorplate.

Carrier coordination

We manage approvals where required.

Monitored & maintained

Optional 24/7 monitoring via Wireless Connect+.

System architecture

The carrier signal chain

CARRIER SIGNAL CHAIN — MACRO SITE TO FULL BARS

  • CARRIER MACRO SITE — BANDS A · B · C
  • DONOR ANTENNA — −95 dBm CAPTURED
  • MULTI-BAND BDA — UP TO +70 dB GAIN, PER BAND
  • SPLITTERS & COUPLERS — BALANCED PASSIVE LOSS
  • INDOOR ANTENNAS — −65 dBm DELIVERED
  • USER DEVICE — FULL BARS · EVERY CARRIER

From the carrier macro site to full bars in the basement: WZC engineers gain, loss, and antenna placement at every link in the chain.

  • RF signal path (dashed = over-the-air)
  • Multi-band amplification
  • Structure & passive distribution

How it works

Our process

  1. Assess

    Signal survey and carrier analysis.

  2. Design

    System sizing and component selection.

  3. Install

    Headend, cabling, and antennas.

  4. Verify

    Coverage testing and handoff.

Donor antennas — where every DAS begins

Why it matters

Coverage your occupants can feel

Dead zones in stairwells, elevators, and low-E glass offices are not an inconvenience — they are lost calls, lost productivity, and frustrated tenants. A properly engineered DAS makes them disappear.

Questions

FAQs

Will this work for all carriers?

Yes, we design carrier-agnostic systems and coordinate carrier approvals when needed.

Is this the same as ERCES?

No. Cellular DAS serves commercial carriers; ERCES serves public-safety responder frequencies and is code-mandated. We do both.
