Caution: Changes or modifications to this product not expressly approved by Nextivity may void your right to operate the equipment.
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. 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.
- Cel-Fi created a new 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 Cel-Fi to deliver a smart solution designed for middleprise buildings - Cel-Fi QUATRA solutions.
- Cel-Fi 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.

How Does It Work?
Cel-Fi QUATRA 4000 is a powerful cellular signal distribution solution. Cel-Fi QUATRA 4000 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 signal sources. The signal source can be off-air (over-the-air (OTA)) from the macro network or delivered via a small cell.
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.
Real World Examples
1. Off Air Install, 75K ft2 building
In this example, Cel-Fi QUATRA is providing cellular coverage for four carriers in a six story 75,000 ft2 building. Individual LPDA antennas are located on the top of the building to ensure the best signal-to-noise ratio at the donor site for all four carriers. Four coax cables are pulled through the roof to Network Unit. 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 ft2 building
This Class A building is a multi-dwelling unit (MDU) apartment complex with approximately 300 units planning for approximately 1,000 users at peak times/capacity. The building owner wanted to ensure optimal capacity and the best possible quality of user experience on site. The system is comprised of four (4) QUATRA 4000 systems served with one small cell from each wireless operator. The small cell signals are split and input to each QUATRA 4000 NU. From the QUATRA 4000 NU the signals are distributed in the vertical run to the CUs 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 carriers, but the other two carriers’ 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 small cells for the two remaining carriers.

Cel-Fi QUATRA 4000 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 4000 system. The signal sources (one for each port/carrier) are connected to the NU. Then they are digitized and purified, and distributed over dual Category cables to the Coverage Units (CU).
Figure 3. NU Image
Note: Only cellular signals may be connected to the donor ports. Other types of radio signals will not work, and may damage the system.
The NU has four (4) N-type RF ports on the top. Each RF port is assigned, and marked, to a specific carrier.
There are two (2) SMA-female ports on the top of the NU. One functions as the external antenna connection for the unit’s internal cellular modem, and the other is for GPS. (The GPS port is for future functionality)
- AC Power Supply (inside the NU)
- AC power cord
- RJ45 ports (13)
- Paired RJ45 ports, 2 per CU served
- LAN port for Internet connection
- SFP+ module dock (future use)
- N-type Female RF Ports (4) for Donor Antenna
- One for each carrier
- SMA port (2)
- Provides an external antenna connection for the internal cellular modem (when used)
Figure 4. SMA Connectors on the NU
- LED interface (front) to indicate system status. (For detail on the LED go to LEDs.)
Power Supply Cable
Coverage Unit (CU)
The Coverage Unit (CU) receives the digitized cellular signal from the NU, converts back to RF, amplifies, and distributes the service from its RF port. Service can be deployed through a single connected antenna, or through a DAS field.
Figure 4. SMA Connectors on the NU
The Coverage Unit includes a multiband blade-style antenna that can be connected directly to the CU.
See Figure 8. CU Antenna
QUATRA 4000 Range Extender (QRE4K)
Model Number: Q40-OE
The QRE-4K unit is a device that extends the standard 100 meter cable length from NU to CU by an additional 100 meters. It is inserted in-line between the NU and CU, and requires no external power. The RJ45 connectors are on each side (two per side).
The donor antennas are used to provide off-air signals to individual carrier donor input ports. The objective is to provide the best quality carrier signals to the NU. A variety of donor antennas are available from Nextivity. The right donor antenna choice can make the difference between a good outcome and a great outcome. Please refer to other antenna-specific documents for choosing the right donor antenna.
Cel-Fi LPDA-R Antenna
Model Number: A62-V44-200

Important: Before any permanent installation, make sure all the components are planned and accounted for, as well as any wiring, cabling, power, mounting, antenna placements, and system access.
Several things need to be determined as part of installation planning and preparation. There isn’t a specific order these items need to be resolved. Depending on the specific needs at the site, varying orders of activity may be employed.
- Perform any required indoor and outdoor signal surveys to understand current signal problems to solve and to assess candidate donor antenna locations.
- Determine where the NU(s) will be mounted.
- Ensure adequate power source.
- Determine donor signal sources and cabling/routing.
- Ensure access to the Category cable runs, connecting to the CU(s).
- Determine where the CU(s) will be mounted and how coverage is to be distributed.
- Determine if the (included) Mini Panel Antenna will be used or a DAS field, for each CU.
- If coaxial cable and antennas are planned for use then that should be considered at this point.
Note: IBWAVE (or other RF planning tools) designs are not required but are a good way to ensure the best performance outcomes.
Installing the NU
The Cel-Fi QUATRA NU is designed for simple wall mounting. Mounting accessories, including screws and anchors, for common material types (drywall, plywood, etc) are included with each NU.
Equipment Required for Mounting
- Drill bit extender (3”+)
- Pencil, or other similar marker
Caution: Make sure the area behind any surface is free of electrical wires or other dangerous elements prior to drilling.
The QUATRA 4000 NU has four (4) secure mounting tabs, two on each side. The two topmost tabs have been keyholed.
Note: The Mounting Instructions below use the standard drywall mounting anchors and screws included with the unit. If the NU is to be mounted onto other surfaces, make sure the appropriate anchors and screws are used (not included).
1. To mount the NU, first determine the approximate location on the wall for the unit.
2. Hold the unit up on the wall and, using a pencil or similar marker, mark one of the top (right or left) points.
3. Drill the holes for the anchors.
4. Hammer in the anchors.
5. Partially screw in the top two screws.
6. Hang the unit from the top two screws, through the eyeholes. Adjust the unit to level and then tighten the screws.
7. Screw in the bottom two screws.
8. Mounting is complete.
Connecting Donor Source
The QUATRA 4000 has four independent RF ports for connecting the donor signal. Each port:
- Is an N-type Female connector
- Is specific to the supported operator
- Supports one and only one operator
- Is designed to support a variety of band configurations
Each RF port can be fed by a donor signal consisting of either a small cell or an antenna. Nextivity offers a number of donor signals perfect for use with Cel-Fi QUATRA 4000.
Note: Small cell inputs and off-air inputs can be used in the same system, but not for the same donor port.
The donor antenna is used to collect the donor signal from the external (over-the-air) carrier network. Better donor signals lead to better customer experiences, improved voice quality and faster data throughput. An RSRP signal-to-noise ratio (SiNR) of > 0 dB is strongly recommended for each given carrier’s source signal. Better SiNR leads to better throughput.
Each donor antenna should be mounted safely and securely where it can access the desired cellular network. A coaxial cable connects the donor antenna to the NU’s RF port for each given carrier.
Small Cell Donor
If a small cell is used as the donor source then it should be connected at this time. The input signal level for the donor port should be between -60 and -50 dBm.
Note: the small cell should be fully-operational in standalone mode prior to being connected to the QUATRA 4000.
The QUATRA 4000 system is powered from the Network Unit (NU). The NU comes with a power cord that plugs in to the back of the unit. The Coverage Units (CU) are Powered-over-Ethernet (PoE) and therefore do not have independent power supplies that need to be plugged in.
The entire system should be installed, CUs located in the desired coverage location, before the system is powered-on. The power cord can be installed, with the switch in the OFF position. When the system is ready to be powered, switch to ON.
Note: It is recommended to zip-tie or otherwise secure the power cord once the system is powered-up, to prevent accidental unplugging.
Installing a CU
The Coverage Unit (CU) comes with a wall mounting bracket in the box. To mount the QUATRA 4000 CU simply follow these steps:
1. Determine mounting location. Note: Whenever mounting any Cel-Fi gear on a wall or ceiling make sure the area is free of any dangerous electrical wires, other safety hazards, or any other objects that could be damaged or effect the quality or stability of the mounted unit.
2. Position the QUATRA 4000 CU wall mount on the wall in the desired mounting location.
3. Holding the mounting bracket in place, mark hole locations with a pencil.
4. Drill the holes.
5. Hammer in the anchors.
6. Attach the bracket to the wall with the included screws.
7. Once the bracket is firmly attached to the wall, the CU can be attached to the bracket.
8. With the bracket in place, attach the CU.
9. Tighten (finger) each Locking Screw into place to ensure the CU is securely attached.
Connecting Server Antenna(s)
The CU has an N-type connector on the top of the unit for attaching an antenna. An omni-directional antenna is included with each CU, or a coax cable can be connected with a series of passive antennas attached.
Figure 12. Connecting Server Antenna or Cable
Connecting NU and CU
Each CU connects to the NU using two Ethernet cables (Cat5e or better).
Figure 13. CU port assignment on the NU
Using a QRE
If distances greater than 100 meters from NU to CU are required, an extra 100 meters can be achieved by inserting the QUATRA RANGE EXTENDER (QRE) between the NU and the CU.
Note: Only the QUATRA 4000 RANGE EXTENDER (QRE-4K) may be used. The QUATRA 1000 and QUATRA 2000 QRE is not compatible with the QUATRA 4000.
The QUATRA 4000 NU has ten (10) LEDs on the front of the unit, used as status indicators, during setup and normal operation. The LEDs are labeled.

Cel-Fi QUATRA Optimization Features
The QUATRA 4000 system can accept up to four individual donor signals. One per carrier. Each donor can be established to the system either via small cell or off-air. When using an off-air signal, a directional antenna is recommended to provide the best signal quality. (Nextivity offers a number of directional antennas that can be used. See www.cel-fi.com/products for details.)
The Antenna Pointing feature allows you to easily optimize the direction your external antenna should be pointed. The algorithm takes into account the system gain and radio environment (including signal strength, signal quality, and pilot pollution).
This feature is designed to work with the Cel-Fi Mount, which is an indoor/outdoor mount with a proprietary 8-position dial base. This dial enables the antenna to be rotated in 45-degree increments.
- Make sure the Cel-Fi COMPASS is connected to the donor antenna using the (included) SMA to N adaptor.
- Click on “Antenna Positioning” in the WAVE PRO app.
- Rotate your antenna to a position on the dial mount and tap the corresponding number button. You will need to test 2 or more positions to see the results.
- The app will show the recommended band to use.
A Full Signal Report scans all bands and channels for each carrier and returns a list of the channels it finds with RF metrics.
- Go to the optimization section in the WAVE PRO app and click on “Full Signal Report”
- Press the "Start Test" button to begin measuring
- Can take up to 20 minutes before the app shows network information
Note: This scan will be quicker and more accurate when you have a SIM card installed.
You can export the Signal Report by selecting the "More" icon and "Email Report". Type in your email address and results will be sent as a text attachment.
This feature tests the speed of the current Network Carrier of the SIM card inserted into the COMPASS.
- In the WAVE PRO app, go to the “Optimization” section and press the "Speed Test" button.
- Click on “Start,” and The Cel-Fi COMPASS will gather data for several minutes and display the results below.
Serving Cell Report
The Serving Cell Report is a live reading of the current Network Carrier of the SIM card inserted into the Cel-Fi COMPASS. The data will constantly refresh while on the page.

A good donor signal, arriving as cleanly as possible, to the NU, is perhaps the most important consideration in driving the best experiences and outcomes with QUATRA 4000.
With regard to 4G LTE, there are two metrics of particular importance to monitor and optimize:
1. RSRP. Reference Signal Receive Power. It is the power of the LTE Reference Signals spread over the full bandwidth and narrowband. A minimum of -20 dB SINR (of the S-Synch channel) is needed to detect RSRP/RSRQ.
In the context of Cel-Fi QUATRA 4000, the following stratification of quality is recognized:
2. SINR. Signal to Noise Ratio. The SINR is the ratio of the usable (desired) signal over the noise. The following metrics should be used when assessing SINR in the context of Cel-FI QUATRA 4000.
There are a few considerations to make when determining the donor antenna.
- How many serving sites? If there are multiple serving sites, and the design goal is to select a specific site, for loading, or any other reason, then directional antenna would be required. If there is a single donor site, and not much RF contention, than an omni-directional antenna could be considered, which would save a little time and energy in the install process, as it would not need to be aimed.
- How much noise? If the site location is very noisy, then a strong directional antenna would be a good choice, as it will filter out some of the unwanted signal.
- How strong is the serving signal? Although Cel-Fi QUATRA 4000 has the highest gain of any antenna in its class, if the serving signal is extremely weak, then a high-gain antenna may be required to connect the uplink calls and to get the optimal DL power on the serving side.
Grounding and Lightning Protection
Installers of Cel-Fi QUATRA 4000 are encouraged to follow the lightning protection guidelines documented in the National Electrical Code (NEC) and NFPA 780, and/or local codes.
The QUATRA 4000 Coverage Unit has a single RF output port in the form of an N-type female connector on the top of the unit. A single whip or blade-style antenna can be attached directly, or a distributed antenna system can be deployed.
There are two types of indoor antenna to choose from:
Omni-directional dome antennas broadcast and receive signals from all sides. They are designed for central locations with 360º coverage requirement. Like outdoor antennas, their power is measured by their “gain”. They are typically mounted to a ceiling for best results.
Nextivity has standard dome antennas and also offers ‘low-profile’ server antennas that are thin and occupy less visual space.
Panel antennas are directional antennas. Panel antennas allow optimum reception to targeted areas. Like with outdoor antennas, a directional antenna is stronger than an omnidirectional antenna which means the signals it broadcasts are stronger. It can be mounted to either the wall or ceiling. We usually recommend placing it on the ceiling for maximum coverage but in some spaces (like a long narrow hallway) the panel antenna can be placed on the wall.
Nextivity has a few different panel antenna options, with different levels of gain and directivity.
MIMO vs SISO
MIMO (multiple in, multiple out) antennas have multiple feeds and typically more than one coaxial (pigtail) cable or connector. Therefore, a MIMO antenna should only be used with a system that supports MIMO. (Cel-Fi QUATRA 1000 supports MIMO.)
A SISO (single in, single out) antenna has a single coaxial (pigtail) cable feed and/or connector, and works best with SISO systems. Cel-Fi QUATRA 4000 is a SISO system.
Mounting (Coverage Unit)
The QUATRA 4000 Coverage Unit is fitted with two ¼”-20 inserts in the center of the bottom side of the unit. This is designed to mate perfectly with standard drop-ceiling infrastructure components. The mounting bracket also has four (4) ¼”-20 threaded inserts which can be similarly used. A variety of mounting methods can be employed through the integration of off-the-shelf accessories.
Note: The Cel-Fi QUATRA 4000 Coverage Unit is plenum rated.

|Donor Antenna||Antenna used to capture the exterior macro cellular network signal, and provide such signal to the system.|
|Server Antenna||Antenna used internally to provide the coverage benefit from Cel-Fi QUATRA 4000.|
|Network Unit Hardware Error||Power cycle the Network Unit (NU) and check for software updates. If problem persists, return NU for service.|
|Insufficient Donor Signal||Relocate Network Unit (NU) where a stronger signal exists, or use an external antenna for the NU. If using a small cell, verify the small cell can process calls and check the connections to the NU. Power cycle the NU.|
|Coverage Unit Hardware Error||Troubleshoot any Network Unit (NU) error first, and check for software updates. Make sure Coverage Unit (CU) cables do not exceed 100m (or 100m + QRE + 100m). Note that standard Ethernet Extenders or active LAN switches and routers will not work with CU cabling. Power cycle the CU by detaching and reattaching the LAN cable. Test CU by plugging it into back of NU with short test cable.|
|Donor Signal Too Strong||Move Network Unit (NU), or re-aim NU external antenna. Strong signal source may be from another Operator's device (cell tower, local small cell, or booster).|
|Network Unit is Overheating||The Network Unit (NU) should be upright and the air vents not blocked. Move NU to a cooler area.|
|Coverage Unit is Overheating||Make sure the Coverage Unit (CU) air vents are not blocked, or move the CU to a cooler location.|
|Too Close||One of your Coverage Units (CU) is too close to your Network Unit (NU). Try moving the units farther apart (or move units so more signal blocking structures isolate them from each other).|
|Too Far||One of your Coverage Units (CU) is too far from your Network Unit (NU). Try moving the units closer together.|
|Disabled by Operator/Vendor||Your system has been disabled by the mobile network operator or vendor. Contact your vendor for further assistance.|
|Location Lock||Your system has been moved from its original address. Please move the system back to its original location or register your new address with your wireless provider.|
|Registration Required||Systems are pre-enabled and carrier registration is obligatory.|
|Self-Test Failed||Power cycle the unit and check for software updates. If problem persists, return the unit for service.|
|Small Cell Not Detected||Network Unit (NU) Mode is set to small cell. Verify that small cell is connected and operational, or set NU Mode to Internal or External Antenna if no Small Cell used.|
|Small Cell Detected||Small Cell Detected but Network Unit (NU) is not set to Small Cell. Use the WAVE Portal to set NU Mode to Small Cell.|
|Antenna Configuration Error||Too Many Coverage Units (CU) connected. More than one CU in use for Off-Air configuration. Use the WAVE Portal to set Mode to External Antenna, and NU should be connected to an external antenna.|
|Antenna Positioning Required||Antenna positioning incomplete. Use the WAVE Portal to aim the NU donor antenna.|
|Ethernet Link Error||The ethernet link between NU and CU is behaving unreliably or reporting an error. Ensure the ethernet cable is not damaged and its connectors are securely plugged in on both ends.|
