Superior FirstNet Connectivity
The CEL-FI QUATRA EVO FN hybrid DAS significantly enhances FirstNet Band 14 connectivity throughout enterprise and government buildings, ensuring reliable communication for first responders when every second counts.
Unmatched Signal Strength
Flexible to varying networking needs, the CEL-FI QUATRA EVO FN features single or dual carrier support with industry-leading gain up to 100 dB – outperforming traditional passive DAS systems. Get maximum boost for AT&T/FirstNet plus T-Mobile or Verizon (if desired).
Optimized Signal Clarity
Nextivity’s patented 4th generation IntelliBoost chip cuts signal noise, optimizing signal strength and quality. That means clear calls, faster data, and uninterrupted communication for first responders as well as employees and customers in all critical areas.
Scales to Any Building
Cel-Fi QUATRA EVO FN systems are custom-designed by our expert installation team to meet your coverage needs and budget. Using category cabling with fiber expansion support, the EVO FN can be tailored to fit any building or campus without signal loss issues.
No excess, no waste, no overrun. Just superior coverage to your specifications.
Stay in Control
Nextivity’s WAVE portal allows remote monitoring and management. Easily track performance, adjust settings, and keep your system running at its best – anytime, anywhere.
The CEL-FI QUATRA EVO FN by Nextivity is an intelligent distributed antenna system designed to enhance 5G/4G coverage in enterprise or government buildings for up to two carriers. Supporting FirstNet Band 14, you can configure the EVO FN to boost FirstNet/AT&T plus another carrier (T-Mobile or Verizon). Whether deployed in single- or double-operator mode, it ensures reliable communication for first responders while also strengthening connectivity for employees and customers.
Featuring industry-leading gain up to 100 dB gain and IntelliBoost technology, the QUATRA EVO FN minimizes signal noise and maximizes performance in any environment– rural, suburban, or urban.
Scalable architecture adapts to buildings and campuses of any size, delivering robust coverage for FirstNet users, staff, and customers where it’s needed most. Category cabling with fiber expansion support enables efficient signal transmission over long distances without degradation, ensuring strong connectivity throughout.
The Nextivity WAVE Portal makes it easy to keep an eye on your system for peak performance.
- QUATRA EVO FN Network Unit (NU): The hub of the system. Features two donor antenna ports: one for AT&T/FirstNet and the other for Verizon or T-Mobile. It works with up to six coverage units, or can be used on its own to provide up to 75,000 sq ft of coverage.
- QUATRA EVO FN Coverage Unit (CU): Extend coverage with ease. Connect up to six CUs to a single NU to scale coverage up to 300,000 sq ft. Each CU is powered by Power-over-Ethernet (PoE) from the NU, reducing installation complexity.
- QUATRA Fiber HUB (Optional): The Fiber Hub allows even more scalability for a Cel-Fi QUATRA EVO FN system at a lower cost overhead. It can be installed up to 2km away from an NU, extending reach while maintaining the same signal quality throughout the system.
- Passive Indoor Antennas: Distribute the signal provided by the QUATRA system. These can be yagi or omnidirectional, panel or dome depending on your building’s layout and design. Each NU or CU can supply up to 16 indoor antennas.
The outdoor antenna captures signal from nearby towers and relays it to the Network Unit (NU), which distributes it via Cat5 cables to each Coverage Unit (CU). Each CU amplifies the signal up to +100 dB. Connected antennas then broadcast the enhanced signal throughout the building, ensuring robust coverage through floors and walls to eliminate dead spots.
We've partnered with Bolton Install Pros to provide full turnkey integration of in-building wireless (IBW) systems that amplify signal indoors, delivering the signal you need to get the job done. From the first call to post-project, Bolton Install Pros handles every detail personally in-house. Their team of RF engineers, system integrators, designers, and certified signal boost specialists take complete ownership of your project.

Can the QUATRA EVO FN Be Set Up Outdoors?
No. The QUATRA units are not weatherproof and must be deployed indoors.
What’s the Difference Between the QUATRA EVO FN and QUATRA EVO?
The QUATRA EVO FN is similar to the standard QUATRA EVO, but with FirstNet support.
Does the QUATRA EVO FN Require Carrier Approval Before Installation?
No. The EVO FN is pre-approved for immediate deployment by AT&T, FirstNet, Verizon, and T-Mobile.
Can the EVO FN Be Configured to Only Boost FirstNet?
Yes, the QUATRA EVO FN can be configured to boost only FirstNet/AT&T. In single-operator mode, the unit will boost four AT&T bands, including FirstNet Band 14, ensuring first responders keep connected during critical moments.
