About This Guide
There are a variety of Cel-Fi QUATRA product variants available, supporting a variety of band configurations,
for multiple regions. This manual is applicable to the Cel-Fi QUATRA 4000c M/N: Q44-1M34NCU ONLY,
and does not apply to any other QUATRA variants.
Safety Precautions
Use Cel-Fi QUATRA 4000c indoors. It should not be used outdoors.
These products are designed to be used with the internal power supply unit that shipped with the Network
Unit. When installing the equipment, all the requirements of the manufacturer and the referenced standards
must be met.
There are no user serviceable parts inside.
Caution: Changes or modifications to this product not expressly approved by Nextivity may void your right to
operate the equipment.
01. Introduction to QUATRA 4000c
Understanding Cellular Coverage
Spotty cellular coverage, poor voice quality, dropped calls, and dead zones continue to plague occupants in
buildings of all shapes and sizes. Nextivity’s Cel-Fi QUATRA solves that problem. It is an affordable, all-
digital solution, providing uniform, high-quality cellular signals throughout a building. Cel-Fi QUATRA is
scalable to fit buildings of all sizes and is carrier approved and guaranteed network safe.
Unlike traditional analog boosters and passive DAS technology, QUATRA delivers a cellular signal that is up
to 1000x stronger, utilizing CAT 5e (or better) cabling for the connection between the head end and each
remote. The remotes are powered via Power over Ethernet (PoE), delivering an un-attenuated signal throughout
the building. Cel-Fi QUATRA can be installed in just days (compared to months typical of other solutions), and
at a price point that meets the middleprise budget.
The QUATRA Solution
While cellular networks are outside, the majority of calls take place inside. A recent study showed 80% of
business users inside complain of poor coverage or dropped calls. Modern building materials, while improving
energy efficiency, will block or inhibit cellular service from the outside network. To exacerbate the issue,
cellular coverage is increasingly critical. In fact, cellular coverage can be considered a safety or even regulatory
requirement, depending on the region. Building owners need a flexible, high-quality solution. Installers and
Value-Added Resellers need a product that can serve the majority of building types and not take months to
deploy.
Nextivity created a new Cel-Fi solution category that combines its core technology with the architecture of
an Active DAS –to deliver an Active DAS Hybrid –carrier-grade but built for Installers.
Integrators and Carriers have partnered with Nextivity to deliver a smart solution designed for middleprise
buildings - Cel-Fi QUATRA solutions.
Nextivity provides the QUATRA BOM Estimator to help installers select the appropriate equipment in the
right quantity, to eliminate the heavy cost/time of the (pre) planning effort.
Cel-Fi’s all-digital, scalable, PoE Category cable-based solution makes it ideal for Single or Multi-Carrier
environments.
Speed of Installation, higher quality in-building cellular solutions, and cost savings –are some of the reasons
building owners, facility managers, and IT professionals are making the smart investment in Cel-Fi QUATRA
solutions.
Comment About FCC Certification
QUATRA 4000c Model Number Q44-1M34NCU supports Part 20 cellular bands.
Cel-Fi QUATRA 4000c Model Number Q44-1M34NCU
The QUATRA 4000c is FCC Part 20 certified for the following bands: 2, 4, 5, 12, 13 and 25
A Solution Anyone Can Confidently Deploy
Cel-Fi QUATRA is designed to improve indoor signal coverage without any risk of interference on the mobile
network. Cel-Fi QUATRA provides a sophisticated network-safe solution that has been rigorously tested
globally, through multiple generations, engineered to deliver multiple levels of network protection:
Uplink power control to prevent desensitizing the network
Echo-cancellation and feedback control to prevent oscillation of the system
Uplink muting, when handsets (UE) are not detected
Signal qualification (channels are individually qualified, so noise or very poor signals won’t be amplified
and degrade the network)
The Cel-Fi WAVE Platform cloud-based portal enables an operator to monitor equipment and network
KPI’s, such as channel configurations, RSRP, RSCP, SINR, and system gains, providing control and
optimization insight.

03. System Overview
How Does It Work?
Cel-Fi QUATRA 4000c is a powerful cellular signal distribution solution. Cel-Fi QUATRA 4000c is
fundamentally comprised of a Network Unit (NU) and up to six (6) Coverage Units (per NU). The Network
Unit takes the donor input from up to four (4) carrier donor signal sources. The signal source can be off-air
(over-the-air (OTA)) from the macro network or delivered via a small cell or PVT (Private CBRS network).
The NU receives and individually processes channels from each carrier, allowing a higher gain for weaker
channels (up to 100 dB). The channels are digitized and sent over a pair of Ethernet cables to each CU for
retransmission through one or more service antennas.
The system may also be used with one QUATRA 4000 FIBER HUB, which functions much like an NU with up
to six (6) additional CUs. The HUB is connected to the NU with up to 2km of optical fiber cable and SFP+
Modules (sold separately), and it uses donor signals from the connected NU.
Architecture Overview
Real World Examples
1. Off Air Install, 75K ft2building
In this example, Cel-Fi QUATRA is providing wireless coverage for three cellular carriers and one optional
CBRS private wireless network in a six story 75,000 ft2building. Individual LPDA antennas are located on the
top of the building to ensure the best signal-to-noise ratio for all cellular carriers, and the enabled CBRS port on
the NU is connected to a PVT signal source. A Coverage Unit is placed on each floor, and a distributed antenna
system (DAS) field is run out from each CU to provide great coverage.
2. Supercell Install, 300K ft2building
This building did not have adequate donor signals for the carriers, so small cells were chosen as the signal
sources. The system is comprised of four (4) QUATRA 4000c systems served with one small cell from each
service operator. The small cell signals are split and input to each QUATRA 4000c NU. From the QUATRA
4000c NU the signals are distributed to CUs on each floor and then horizontally to a DAS field, providing
coverage to the building.
3. Hybrid Install, Off-Air + Small Cell
In this example, the building site has excellent (exterior) network service for two cellular carriers, but the other
carrier outside signals are very poor. The System Integrator has decided to use a hybrid approach, taking off-air
signals from the two carriers with good service and implementing a small cell for the remaining carrier plus a
PVT CBRS signal source.

04. Hardware Components
Cel-Fi QUATRA 4000c is a modular solution with two (2) foundational components: the Network Unit (NU)
and the Coverage Unit (CU). In traditional DAS terminology, these could be known as the Head End (NU) and
the Remote Unit (CU).
Power is provided to the entire system through AC power at the NU. The CUs are powered via Power over
Ethernet (PoE), and therefore do not require a separate power source at their location. Signal source is brought
into the system at the NU, via a wired connection, like a small cell, or through a donor antenna and an RF
connection.
Network Unit (NU)
The Network Unit, referred to as the NU, is the head end for the QUATRA 4000c system. The signal sources
(one for each port/carrier) are connected to the NU. Then they are digitized and distributed over two Category
“Ethernet” cables to the Coverage Units (CU).
