Improve weak mobile signal instantly
Fixtel delivers expert Cel-Fi signal booster supply, installation, and ongoing support for homes, offices, apartments, warehouses, and commercial buildings throughout Australia.

What is a Cell-Fi Signal Booster Service?
Poor mobile signal is not just frustrating, it costs your business money. Dropped calls, failed payment terminals, slow mobile data, and dead zones throughout your building affect productivity, customer experience, and revenue every single day.
Cell-Fi signal booster service delivers a complete, end-to-end solution, from expert site assessment through to professional installation and ongoing support. We do not just sell you a device. We solve your signal problem.
Cel-Fi is the only mobile signal booster approved by Telstra, Optus, and Vodafone for use in Australia, and the only one that complies fully with ACMA regulations. It supports 2G, 3G, 4G, and 5G networks, future-proofing your investment.

Key Features and Benefits
- Better Coverage: Eliminate dead zones and black spots across up to 900m² per unit. Every room, floor, and corner gets a reliable signal, not just the ones facing the street.
- No Dropped Calls: Crystal-clear voice calls with no signal drop. Whether it is a client call or an emergency, your connection holds. No more stepping outside just to make a call.
- Improved Data Speed: A stronger signal means faster 4G and 5G data speeds. Improve browsing, video calls, cloud access, and EFTPOS processing, all from the same devices you already use.
- Easy, Professional Installation: Our qualified technicians handle everything, including site assessment, antenna placement, cabling, and commissioning. No guesswork, no DIY headaches, just a complete working solution.
- Carrier-Approved and Legal: Cel-Fi is the only booster approved by Telstra, Optus, and Vodafone in Australia. Fully ACMA-compliant, it protects your network and the people around you.
- 5G Ready: The Cel-Fi GO G51 supports current and future 5G networks with firmware updates. Your investment grows with technology.

Who We Help: Use Cases
- Homes and Apartments: Thick walls, tinted windows, and building materials block outdoor signals. Cel-Fi ensures every room, including basements and upper floors, stays connected for your whole household.
- Offices and Commercial Spaces: Keep your team connected in meeting rooms, open floors, and lifts. Better signal means better productivity, reliable payment processing, and fewer communication breakdowns.
- Rural and Remote Properties: Distance from towers, hills, and trees all drain signal strength. Cel-Fi amplifies what little signal exists and turns one bar into full indoor coverage, even on farms and rural worksites.
- Apartment Buildings: Tenants expect strong mobile signals. We work with body corporates and strata managers to deliver building-wide coverage that protects property value and tenant satisfaction.
- Warehouses and Industrial Sites: Steel structures, concrete walls, and large footprints are signal killers. Cel-Fi’s scalable systems deliver consistent coverage across even the most challenging layouts.
- Health and Aged Care: Reliable mobile communication is critical in clinics, hospitals, and aged care facilities. Cel-Fi’s compliant, interference-safe design makes it the right choice for regulated environments.
How It Works
You do not need a new SIM card, a new plan, or a new phone. The same devices you already use will simply work better.
