Eliminate dead zones, dropped calls, and slow data speeds. We design and deploy ACMA-compliant, carrier-approved cellular amplification solutions for commercial high-rises, warehouses, and remote facilities.
As authorized engineering partners with Nextivity, we have direct access to back-channel carrier relations, top-tier technical escalation, and the latest hardware standards.
Years in Cellular Engineering
Over a decade designing, installing, and certifying In-Building Coverage (IBC) solutions across Australia.In Australia, mobile phone frequencies are heavily regulated by the ACMA. Operating unapproved wideband cellular boosters is illegal, and carries substantial fines. Why? Standard boosters create network-wide feedback loops, blocking signal towers for surrounding users.
Cel-Fi products by Nextivity are the ONLY ACMA Class Licensed, carrier-approved cellular boosters in Australia. Driven by the intelligent IntelliBoost microprocessor, they constantly monitor local radio parameters, ensuring they remain 100% network-safe without introducing noise or interference to carrier cell sites.
From remote single-carrier workspaces to multi-million square-foot metropolitan high-rises, there is a Cel-Fi hardware profile designed for your footprint.
The gold standard for small-to-medium offices, retail stores, and large homes. The GO G41 offers class-leading 100dB signal gain, easily switchable between Telstra, Optus, or Vodafone via the WAVE app.
Engineered specifically for moving assets, transport fleets, and marine vessels. The G31 dynamically locks on to cellular tower handoffs while traveling through low-signal areas.
Perfect for multi-user commercial layouts requiring concurrent dual-band carrier amplification. Provides pristine voice clarity and accelerated LTE data throughput for regional hotspots.
An enterprise-class multi-carrier solution. Uses lossless RF-over-Ethernet (category cabling) to deliver uniform, multi-carrier coverage for massive commercial buildings, hospitals, and warehouse hubs.
Modern architecture is the enemy of radio signal. Low-E double glazed glass, reinforced concrete cores, and heavy structural steel create an effective Faraday Cage, blocking outdoor cellular carrier signals from entering your building.
This signal blockage leaves staff with dropped voice calls, stagnant mobile data, and severe battery drain as devices desperately crank transmit power to locate a tower. Our bespoke IBC designs bypass these obstacles completely.
Provides perfect signal depth in basements, underground parkings, elevator shafts, and remote boardrooms.
Dramatically improves data speeds, eliminating productivity lags and buffering video conferencing.
When mobile signals are robust, devices require up to 80% less transmit power, extending cell phone battery life.
Ensures critical emergency services and triple-zero connectivity remain active in emergency scenarios.
We design a clean, reliable, and logical cellular signal loop that pulls raw carrier tower power and redistributes it directly to your workspace.
A high-gain directional antenna is mounted on your building's roof, aligned to target the strongest line-of-sight carrier cell towers.
The G41, G32, or QUATRA Network Unit acts as the brain, purifying, boosting, and filtering the signal to ACMA-approved levels.
The boosted signal is routed over high-grade coaxial or Cat6 Ethernet cables with zero signal attenuation or local degradation.
Low-profile omni-directional ceiling dome antennas scatter crisp, multi-bar voice and high-speed data down to end users.
We are premium network engineers, not generalist electricians. We treat cellular coverage as an integrated branch of your IT architecture.
We don't guess coverage. We use Nextivity COMPASS scanners to execute detailed physical RF mapping before any cable is run.
We handle the complete link budget documentation and paperwork required for Telstra, Optus, and Vodafone approvals.
Our engineers remotely manage and monitor your Cel-Fi hardware, deploying proactive firmware updates and optimizing isolation.
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.
