Reliable mobile connectivity is becoming an essential service, yet many enterprise buildings continue to suffer from poor indoor coverage and frustrating dead zones. The CEL-FI QUATRA 4000e offers a breakthrough solution, providing a scalable, high-performance, cost-effective answer to in-building cellular coverage.

Traditionally, the only path for indoor coverage in medium to large commercial spaces was a full-scale IBC solution. This is prohibitively expensive and largely left to large hospitals, shopping centres and airports.

The CEL-FI QUATRA 4000e provides the stop gap solution, extending existing coverage indoors via local off-air donor sites. Unlike traditional DAS solutions, QUATRA 4000e is designed for rapid deployment, ensuring seamless connectivity in just days.

Scalable and future-ready

The system can start small, with only a few coverage units, and grow as needed, extending into underground carparks, or into future extended developments over time.

The system also supports expansion via the CEL-FI QUATRA 4000e Fibre Hub and Fibre Range Extenders, enabling coverage extension up to 2 kilometres, to support installation over multiple sites.

Carrier approved hybrid DAS system available

Australia’s high regulatory environment ensures reliable cellular communications. The QUATRA 4000e is the only carrier-approved hybrid DAS system in Australia that offers a cost-effective solution for medium to large indoor coverage.

Remote management and easy maintenance

One of the biggest challenges with in-building coverage solutions is the complexity of monitoring and maintenance. Nextivity addresses this via its cloud-based WAVE Portal which facilitates the remote monitoring and management of system performance. Combined with the Quatra 4000e’s intelligent self-monitoring capabilities, reliability is ensured with minimal ongoing maintenance.

Leverage RFI’s expertise

RFI have extensive experience in RF design, including everything from large scale passive DAS systems, down to the design and manufacture of carrier grade, low noise antennas utilised in these systems.

Leverage our strength in RF, whether you’re a building owner, service provider, or system integrator – we are here to support your journey with the Quatra solution.

Quatra 4000e is available from RFI Technology Solutions. Visit rfi.com.au for more details.
