The First Combined Public and Private Cellular Coverage Solution

Region: United States
Public Cellular Bands: 2, 4, 5, 12, 13, 25, 30*, 71*
(*Available only with Industrial Upgrade via WAVE Portal)
Private Networking Band: 48**
(**Available only with PVT port unlock)

As the market’s first neutral host Active DAS Hybrid cellular coverage solution with the convergence of private networking, CEL-FI QUATRA 4000c combines the industry-leading cellular coverage that CEL-FI QUATRA systems are known for with CBRS private networking capabilities.

Boost Every Carrier Now,
Add Private Networking Anytime

By offering multi-operator coverage, CEL-FI QUATRA 4000c ensures everybody in the building can stay connected and take full advantage of their mobile devices. The system also gives businesses the flexibility to expand their wireless connectivity strategy to include a private network alongside reliable public cellular coverage.

  • Three donor ports for boosting AT&T, Verizon, and T-Mobile signals (3G, 4G, and 5G)
  • Private networking port for easily adding a private networking signal source
  • Latest Nextivity proprietary IntelliBoost technology for industry-leading performance
  • Scalable all-digital architecture with category cabling and Power over Ethernet (PoE)
  • Public cellular signal source flexibility: off-air or small cell
  • System can be installed, commissioned, and activated within days
  • Remote monitoring and management via Nextivity WAVE Portal

Four Ports for All Your Cellular Needs

Three Public Cellular Ports
Each public cellular port is unique to a carrier (AT&T, Verizon, and T-Mobile). By connecting the donor antenna to its respective port, CEL-FI QUATRA 4000c receives the strong signal that’s outside, brings it indoors, and distributes it throughout the building.

One Private Cellular Port
It’s one thing to add a private network to your wireless strategy, but it’s another to make sure the network is always accessible. When a signal source is connected to the PVT port, QUATRA 4000c distributes the private networking signal and ensures it reaches every corner of the building.

Unlock the Benefits of Private Networking

Improved Security
Private networks provide businesses with an extra layer of security for sensitive data, as they are not accessible to the general public and can be configured with additional security measures such as encryption and authentication. This is particularly important in the context of Industry 4.0, where data is often generated by a large number of sensors and devices that are distributed across a manufacturing plant or supply chain.

Enhanced Performance
Private networks can offer improved performance compared to public cellular or Wi-Fi, as they are not subject to the same levels of congestion and interference. This can be especially beneficial for real-time applications such as machine learning or predictive maintenance, which rely on rapid data transmission and analysis.

Greater Control
Private networking can provide businesses with greater control over their data and communication infrastructure, enabling them to customize and configure their networks to meet their specific needs and requirements.

Reduced Costs
Businesses can benefit from private networking by simplifying network management to reduce costs.

Pair with HARMONY

The Nextivity HARMONY Private Networking Service is a cost-effective, low-risk entry point into private networking. The system pairs perfectly with CEL-FI QUATRA 4000c, allowing business to address the public cellular coverage and private networking components within their complete wireless strategy.

System Components

QUATRA 4000c Network Unit

As the hub of the system, the Network Unit (NU) features four donor ports: three operator-specific ports (AT&T, Verizon, and T-Mobile) and one for a private networking signal source. Each NU can support up to six Coverage Units via PoE to deliver reliable public and private cellular coverage inside enterprise buildings.

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

Model Number:

QUATRA 4000c Coverage Unit

The Coverage Unit (CU) is the remote unit that rebroadcasts the donor signal. The system’s category cable, PoE architecture allows installers to easily scale QUATRA 4000c solutions and use up to six CUs per NU.

  • Provides coverage throughout facility (up to six per NU)
  • Power delivered by Power over Ethernet from the NU
  • Self-configuring and self-optimizing
  • Only compatible with QUATRA 4000c NU

Model Number:

QUATRA 4000c Fiber Hub (Optional)

The QUATRA 4000c Fiber Hub expands the NU capacity, enabling a single NU to support an additional six CUs (12 total). The Fiber Hub can be installed 2.0 km (1.24 M) away from the NU to cover large spaces while maintaining the same signal quality throughout the system.

  • Donor source over fiber
  • FCC certified
  • SFP+ module not included
