In-building 4G and 5G cellular coverage. Designed. Installed. Validated.

Macro networks stop at the building facade. Concrete, glazing, and metal cladding block outdoor signal before it reaches your ward, plant room, or basement. Inside hospitals, industrial sites, and critical facilities, in-building cellular coverage has to be engineered for the space, installed to carrier standards, and tested against real thresholds. That is what we do.

The Real Problem

Macro networks were built for outdoor coverage. Inside your building, you are on your own.

Building materials attenuate cellular signal by 20 to 40dB. Reinforced concrete, energy-efficient glazing, and metal cladding are not obstacles the macro network can overcome. The result is dead zones in the exact spaces where mobile connectivity has clinical, operational, or safety consequences.

Coverage in the carpark does not guarantee coverage in the ward. In-building 4G and 5G for hospitals, health networks, and critical facilities must be engineered to the building, validated against carrier thresholds, and documented. Assumption is not a coverage strategy.

Uncertified consumer-grade boosters are illegal under ACMA regulations. Every in-building cellular installation AAA delivers is carrier-approved and ACMA-compliant.

In-Building Cellular

Dead zones in critical spaces?
We'll map it and fix it.

ACMA-compliant in-building cellular solutions validated across all carriers. AAA designs, installs, and certifies passive and active DAS for hospitals, data centres, and commercial facilities nationwide.

Signal Assurance

Validated coverage. Not assumed.

Every installation AAA delivers is tested against real carrier thresholds. RSRP, SINR, and download throughput measured at every zone. Results documented and handed over with the job.

What We Deliver

In-building cellular. End to end.

RF survey, system design, DAS and repeater installation, all-carrier validation, and documented handover. On live sites. All Australian carriers. No shortcuts.

RF Survey and Coverage Design

We measure existing signal strength across all relevant frequency bands before specifying a solution. Dead zones mapped. Building layout documented. Carrier requirements confirmed. The design is produced before a single antenna is mounted.

CEL-FI Smart Repeater Systems

CEL-FI G41 and G51 smart repeater systems for single-carrier in-building coverage. Carrier-approved, self-optimising, and ACMA-compliant. The right solution for hospitals, healthcare facilities, and commercial environments at mid-range scale.

Quatra DAS Systems

Distributed antenna systems for large or complex buildings requiring multi-carrier, multi-band coverage. Quatra 1000 and 4000e platforms for hospitals, industrial critical facilities, and enterprise campuses where all-carrier coverage is non-negotiable.

All-Carrier Coverage Validation

Post-installation walk testing across Telstra, Optus, and TPG/Vodafone. RSRP and SINR measurements documented per zone. Coverage verified against carrier performance thresholds before handover. No sign-off without passing results across all carriers.

Carrier Approval and Telstra Alignment

As a Telstra Partner since 1992, our in-building cellular installations align with Telstra availability and resilience standards. We manage the carrier approval process and confirm every solution meets network requirements before go-live.

Hybrid and Passive DAS Solutions

Where active DAS is not warranted, we design and install passive distributed antenna systems and hybrid solutions combining indoor and outdoor signal sources. Coverage where it is needed. Scaled to the facility.

How We Work

Survey first. Nothing goes live unvalidated.

Every in-building cellular project starts with a site survey. Every installation closes with carrier-aligned validation. There is no shortcut between the two.

01

RF Survey and Site Assessment

Existing signal measured across all frequency bands. Dead zones mapped. Building materials and layout documented. Carrier requirements confirmed before design begins.

02

Solution Design and Carrier Alignment

System design produced and submitted for carrier alignment before installation starts. Equipment selection, antenna placement, and cabling routes all confirmed in advance.

03

Installation on Live Site

CEL-FI repeater, Quatra DAS, or passive distributed antenna system installed with minimal disruption. All cabling run to structured cabling standards. Every antenna labelled and documented.

04

Validation and Documented Handover

Walk testing across all carriers post-installation. RSRP and SINR results documented per zone. Carrier acceptance managed. Full as-built documentation handed over.
