QUATRA 4000c Components & Specifications

QUATRA 4000c is an all-digital hybrid DAS built on two core components, with two optional upgrades to scale coverage and add capabilities.

Nextivity Quatra 4000c Network Unit

Network Unit (NU) - Model Number Q44-1M34CNU

The Network Unit (NU) is the head-end of the QUATRA 4000c system. It's built with three donor antenna ports and a private networking port. Received signals are digitized and distributed over Cat5e/Cat6 Ethernet cabling to each Coverage Unit (CU). Each NU supports up to six CUs to deliver reliable public and private cellular coverage in buildings of any size.

QUATRA 4000c Configurations

The QUATRA 4000c's all-digital, hybrid DAS architecture supports several system configurations to enhance mobile connectivity across small to large enterprise environments. Our team will help configure a unique QUATRA 4000c solution with a tailored quantity of CUs and antennas to fit your space. Under optimal conditions, a QUATRA 4000c offers up to 200,000 sq ft of coverage.

This configuration brings in signal from three carriers (AT&T, Verizon, and T-Mobile) and a private network signal source (optional). Signal is distributed across six CUs and broadcast by 18 indoor antennas, enhancing public and private coverage throughout a multi-story building. The number of CUs and antennas installed will vary by building.

* Coverage values are estimated. Actual results vary based on outdoor signal conditions and building layout.

Configurations

This configuration brings in signal from three carriers (AT&T, Verizon, and T-Mobile) and a private network signal source (optional). A Fiber Hub is used to add capacity to the NU and extend coverage to a second building. Signal is distributed across 12 CUs and broadcasted by 36 indoor antennas. One head-end delivers significantly stronger cellular signal across a multi-story, multi-building campus.

* Coverage values are estimated. Actual results vary based on outdoor signal conditions and building layout.

Frequently Asked Questions

Who Is the QUATRA 4000c For?

The QUATRA 4000c is designed for commercial spaces of all sizes where cellular signal is available outdoors but unreliable indoors. It’s ideal for hospitals, retail spaces, multi-story buildings, large offices, and other enterprise environments.

How Much Coverage Can I Expect from the QUATRA 4000c?

A full-scale QUATRA 4000c system covers up to 200,000 sq ft under optimal conditions. Actual performance will depend on existing cellular signal strength. For smaller spaces, the system can be scaled down with fewer Coverage Units and antennas.

What's the Difference Between the QUATRA 4000c and the QUATRA 4000i?

The QUATRA 4000c is FCC Part 20 certified. It supports bands 2, 4, 5, 12, 13, 25. The QUATRA 4000c also allows for CBRS private wireless networks through its fourth antenna port.

The QUATRA 4000i is an FCC Part 90 industrial cellular booster solution supporting bands 2, 4, 5, 12, 13, 25, 26, 30, 41, and 71. It requires carrier approvals to deploy.

Does the QUATRA 4000c Require a Carrier Agreement?

No. It's FCC Part 20 certified and network-safe. It's ready for immediate deployment by certified commercial DAS installers

Can the QUATRA 4000c Improve Cellular Reception Outdoors?

The QUATRA 4000c is designed for indoor use, improving cellular reception throughout the areas where guests and employees need it most. It is not intended for outdoor use.

Can the QUATRA 4000c Be Managed Remotely?

The QUATRA 4000c can be managed through the Nextivity WAVE Portal. Integrators and IT teams can monitor system performance, receive alerts, change configurations, and push software updates at any time. Issues can often be found and fixed remotely, without an on-site visit.
