Improve your indoor cellular coverage with CEL-FI QUATRA EVO, a scalable solution for enterprises seeking to enhance connectivity for one or two operators with advanced technology and easy installation.


The CEL-FI QUATRA EVO is a state-of-the-art cellular coverage solution engineered to address indoor signal challenges in enterprises such as retail stores, educational institutions, hotels, and healthcare facilities. It offers a versatile solution for enhancing indoor cellular reception for one or two operators across bands 1, 3, 7, 8, 20, and 40 (Port A Only), making it an ideal upgrade from QUATRA 1000 and QUATRA 2000 systems.

Key Features:

  • Operator Flexibility: Supports one or two operators, providing a two-port solution that can amplify up to four bands from a single carrier in single-operator mode or two bands from each operator in dual-operator mode.
  • Scalable Architecture: Features a scalable all-digital design that can support up to six Coverage Units (CUs), with the option to expand to twelve CUs via an optional fiber hub.
  • Advanced Technology: Utilizes IntelliBoost technology for unparalleled echo cancellation, gain control, and coverage footprint, ensuring 3G, 4G, and 5G compatibility.
  • Efficient Installation: Designed for easy setup with category cabling and Power over Ethernet (PoE), minimizing operational disruptions during installation.

Configuration Modes:

  • Single-Operator Mode: Allows connection of a single donor signal to both ports for enhanced coverage of four bands from the same carrier.
  • Dual-Operator Mode: Supports different donor antennas for each port, enabling two bands from each of the two operators for comprehensive building coverage.

CEL-FI QUATRA EVO’s proprietary technology intelligently connects devices to the best available operator bands, ensuring superior connectivity for users. Its flexible configuration and hassle-free installation make it a superior choice for any enterprise seeking to overcome indoor cellular signal limitations.

System Components

QUATRA EVO Network Unit

The Network Unit (NU) is the hub of the system. Each NU works with one to six Coverage Units (CU) for maximum scalability and design flexibility.

  • Receives donor signal(s) for the system
  • Provides power and distributes donor signal(s) to CUs (up to six)
  • Connects via Ethernet or LTE Modem to the Nextivity WAVE Platform for remote monitoring and management

QUATRA EVO Coverage Unit

The Coverage Unit (CU) is the remote unit of the system that rebroadcasts the donor signal. The cost-efficient and easy-to-deploy system leverages Power over Ethernet (PoE) for up to six CUs.

  • Distributes signal across the coverage area inside the building (up to six per Network Unit)
  • Power delivered by Power Over Ethernet from the NU
  • Self-configuring and self-optimizing
  • CEL-FI QUATRA EVO CU is only compatible with CEL-FI QUATRA EVO NU

QUATRA EVO Fiber Hub (Optional)

CEL-FI QUATRA EVO Fiber Hub expands the Network Unit capacity from six to up to twelve Coverage Units. The fiber hub can be installed 1.24 miles (2.0 km) away from the NU to cover large spaces while maintaining the same signal quality throughout the system.

  • Donor source over fiber
  • Ofcom and ComReg Approved and FCC certified
  • SFP+ module not included
