The CEL-FI QUATRA 4000e is a scalable Active DAS hybrid system designed to deliver strong, uniform indoor mobile coverage across large buildings and distributed facilities.
Unlike small repeaters or consumer boosters, the QUATRA 4000e is engineered for enterprise environments where coverage must extend across multiple zones, floors and building sections.
The system provides:
- Consistent 4G and 5G in-building cellular coverage
- Multi-carrier support
- Scalable coverage units across large footprints
- Carrier-approved, network-safe operation
- Remote monitoring via the WAVE platform
This makes it ideal for properties requiring reliable, compliant mobile coverage throughout an entire site — not just a single room.
Why Large Buildings Lose Mobile Signal
Many commercial and community facilities experience mobile signal loss due to:
- Reinforced concrete construction
- Steel frameworks
- Underground and basement levels
- Large floorplates
- Multi-building layouts
- Dense modern construction materials
These structural factors significantly reduce indoor signal strength, creating black spots even when external coverage exists.
A professionally designed in-building mobile coverage solution ensures signal is distributed evenly and safely across the entire facility.
Mobile Coverage for Retirement Villages
Retirement villages rely on consistent mobile coverage to support:
- Resident communication
- Staff coordination
- Emergency call access
- Security systems
Mobile black spots in shared facilities, independent living units or communal areas can create unnecessary risk.
The CEL-FI QUATRA 4000e distributes reliable indoor mobile signal across large retirement communities, ensuring strong coverage where it matters most.
Underground Carpark Mobile Signal Solutions
Underground car parks frequently have little to no mobile reception due to concrete and subterranean construction.
Reliable mobile coverage in carparks improves:
- Emergency call reliability
- Safety for residents and visitors
- Communication for staff and security
- Overall property value and user experience
A properly designed QUATRA system restores dependable cellular coverage in underground environments.
Shopping Centre Mobile Coverage
Shopping centres depend on strong mobile connectivity for:
- Retailer operations
- EFTPOS backup
- Customer communication
- Staff coordination
- Mobile app engagement
Large retail floorplates and internal shop fit-outs often block signal between zones.
The CEL-FI QUATRA 4000e provides consistent mobile coverage across retail corridors, food courts, carparks and tenancy areas.
School and Campus Mobile Coverage
Schools and campus environments require dependable mobile connectivity for:
- Staff communication
- Parent contact
- Emergency readiness
- Campus-wide accessibility
Multi-building layouts and older infrastructure can cause inconsistent reception across classrooms and common areas.
A scalable in-building cellular coverage system ensures strong mobile signal throughout the campus.

Unlike illegal mobile boosters sold online, the CEL-FI QUATRA 4000e is carrier-approved and designed to operate safely within Australian network requirements.
This ensures:
- No interference with nearby towers
- Stable signal amplification
- Long-term compliant operation
- Reliable performance across multiple carriers
For enterprise property owners and facility managers, compliance is essential.
