Buildings are designed to be energy-efficient and insulated from outside noise and weather.
However, the materials that make them so effective — like concrete, metal, tinted glass, and dense insulation — also tend to weaken or block mobile signals, making it harder for phones to connect with nearby cell towers.
Say goodbye to dropped calls, buffering, and poor reception. IBC systems deliver consistent signal strength across every corner of your building — even underground or in signal blackspots.
Better indoor coverage means clearer voice calls, faster internet speeds, and more reliable app performance.
Custom-designed systems can target specific trouble zones like basements, server rooms, or thick-walled areas.
Carrier-approved solutions like CEL-FI work with Telstra, Optus, and Vodafone, so everyone can stay connected.
We deploy cutting-edge in-building coverage solutions powered by Nextivity’s CEL-FI technology
Whether for homes, offices, warehouses, or remote sites, our CEL-FI certified installations ensure reliable connectivity where it matters most.
CELFI products are the only ACMA-approved mobile signal repeaters legally authorised for use in Australia. Fully endorsed by Telstra, Optus, and Vodafone, and trusted by over 200 carriers globally.
Using unauthorised repeaters is not only illegal under ACMA regulations but risks interference with carrier networks.
CELFI solutions are powered by Nextivity’s IntelliBoost® chipset — a smart, real-time signal processing engine that adapts to network conditions in milliseconds. Combined with the WAVE app platform, users get complete control and visibility over performance, diagnostics, and updates.
A Cel-Fi system is a carrier-approved solution engineered to enhance mobile signal coverage within buildings where reception is weak or inconsistent.
By capturing the external mobile signal, Cel-Fi devices ensure reliable voice, text, and data performance across supported 4G and 5G.
Unlike conventional repeaters, Cel-Fi systems use smart signal processing to deliver high-gain amplification without causing interference to mobile networks.
We specialise in delivering tailored In-Building Coverage (IBC) solutions that are fully compliant and carrier-approved.
With over 10 years of experience across commercial, residential, and industrial sites, we deliver seamless mobile indoor coverage solutions.
We are an officially approved Nextivity Partner, giving us direct access to certified CELFI solutions, the latest technology updates, and priority support. This partnership reinforces our commitment to providing industry-leading, carrier-authorised coverage systems you can trust.
CELFI is a smart signal booster designed to improve mobile coverage indoors by amplifying existing 4G and 5G signals. It provides reliable connectivity in areas where mobile reception is weak or inconsistent.
Yes. CELFI is the only carrier-approved Active DAS Hybrid Booster permitted for use in Australia. It meets all ACMA regulations and does not interfere with mobile networks.
Yes, CelFi models like the Cel-Fi GO G51 and QUATRA 4000e support 5G on selected frequency bands, depending on carrier availability and network configuration.
The system uses an external donor antenna to capture the mobile signal, a smart booster unit to amplify it, and one or more indoor antennas (domes or panels) to distribute the signal inside the building.
CELFI is ideal for a wide range of environments including:
Offices and commercial spaces
Apartment buildings and homes
Aged care and healthcare facilities
Warehouses and industrial sites
Retail stores and educational institutions
No. CELFI does not rely on Wi-Fi or internet backhaul. It amplifies the mobile signal directly from the network.
*Internet Connected solutions may be required for remote monitoring services.
The number of indoor antennas depends on the size, layout, and construction of the building. Larger or multi-storey buildings typically require multiple antennas for full coverage.
