Nextivity’s Cel-Fi WAVE Platform
Cel-Fi WAVE is the cloud-based software platform from which Cel-Fi apps and connected capabilities are hosted and driven. Current-generation Cel-Fi products include embedded connectivity technology that allows them to communicate with the WAVE cloud. The WAVE portal and apps are used to facilitate registration, commissioning, installation, optimization and troubleshooting. Over time, the Cel-Fi WAVE platform continues to expand in features and function.
The Cel-Fi WAVE Platform enables device management and maintenance of Cel-Fi QUATRA systems. Alerts and alarms can be used as configured out of the box or they can be customized however the owner or admin chooses.
Additionally, the metrics reported by systems monitored through the WAVE cloud are particularly useful for Support and Troubleshooting.
QUATRA: Sites. Solutions. Systems.
The example below is an illustration showing a single QUATRA 1000 system, connected to the Wideband MIMO Panel Antenna, with a single QRE deployed, and four (4) Coverage Units (CU). Each QUATRA 1000 system supports one carrier.
A QUATRA system is comprised of a Network Unit (NU) and one to four Coverage Units (CU). An NU and CU are paired; they must be of the same model, and band configuration. Multiple QUATRA systems can be installed together to form a larger solution. Systems can be attached to a specific site in WAVE, and managed accordingly, as a group. A site represents a physical location, in WAVE; an address.

03. Configuration Modes (Options)
Off-Air
Selecting the Right Donor Antenna
The QUATRA 1000 system is provider-specific and supports MIMO capability. For that reason, for best performance, in Off-Air mode, each NU should be connected to a high-gain directional MIMO antenna. The Cel-Fi Wideband MIMO Panel Antenna (model: A52-X12-100) is perfect for this application. Used with the AntennaPositioning application (via WAVE) and a Cel-Fi Mount ensures that the system will have the best donor signal possible.
The QUATRA 2000 system includes a dual-carrier, software configurable NU. Donor antenna options are the dual feed Omni antenna if signal quality is very good, or a pair of summed LPDA antennas if SINR is a problem.
SiNR < 0dB = use the LPDA antenna
SiNR=> 0dB = use either the LPDA antenna or the MIMO Panel Antenna
Small Cell (Supercell)
A Supercell is comprised of a Cel-Fi QUATRA 1000 system connected to a small cell. Multiple Cel-Fi QUATRA 1000 systems can be connected to a single small cell, or multiple small cells, to form a coordinated Supercell that extends coverage for large venues. A Supercell with multiple Cel-Fi QUATRA 1000 coverage units (CUs) is more efficient than multiple small cells, and the CUs of a Cel-Fi QUATRA 1000 system connected to a Supercell do not interfere with one another.
Cel-Fi QUATRA 1000 installers with carrier-approved small cells to deliver better RF distribution through CUs, utilizing the full capacity of the small cell, minimizing interference significantly, and requiring much less network management resources. This achieves the major goal of in-building network densification.
Note: Be sure to choose the System Mode “Small Cell” in the Cel-Fi WAVE Portal when connecting a CelFi QUATRA 1000 Network Unit to a Small Cell.
Determining the Proper Configuration
Developing a coverage plan is made easier with Nextivity’s online QUATRA BOM Estimator (QBE). Simply enter information about the site and known requirements, and the QBE will return an estimated equipment list.
The QBE algorithms are based on ever-evolving IEEE 802.16 propagation models, and will provide a very good estimate in most cases. Once on site, it’s always good to measure actual values to ensure best performance, and for any solution adjustments.
04. Guidelines for a Safe Installation
Important: Make sure you have read and understand the Guidelines for a Safe Installation prior to planning and installing the Cel-Fi QUATRA 1000/2000.
To ensure that the installation is aligned with the product safety instructions additional space requirements may need to be considered, as illustrated below.

Radio Frequencies
Exposure to Radio Frequencies
Your device is a radio transmitter and receiver. It is designed not to exceed the limits for exposure to radio waves recommended by international guidelines if installed as specified. These guidelines were developed by the independent scientific organization ICNIRP and include safety margins designed to assure the protection of all persons, regardless of age and health.
The guidelines use a unit of field strength. The field strength limit for routers and small cells are frequency dependent. When tested at 20 cm the device is fully compliant with limits set in international guidelines.
Antennas MUST be installed at least 20 cm from any person.
QUATRA CU viewed from the top would recommend these safe distances:
QUATRA CU when viewed from the side, would result in this safety recommendation:
Field strength is measured utilizing the device’s highest transmitting power and where supported with multiple simultaneous transmitters.
The tests are carried out in accordance with CENELEC EN50385
Interference
- Care must be taken when persons with personal medical devices, such as pacemakers and hearing aids, can come close to the device.
- Do not install the Cel-Fi QUATRA in areas where it is not allowed to operate radio transmitters.
Interference with Personal Medical Devices
- Care must be taken when persons with personal medical devices, such as pacemakers and hearing aids, or others, can come close to the device.
- European standards requires that persons with active implanted medical devices can either assume that their AIMD is sufficiently protected against interference if field strengths are below ICNIRP limits or that they receive specific instructions if their AIMDs are more sensitive.
- Persons with personal medical devices should at least keep a distance of 20 cm. In case of any questions they should consult a medical doctor.
Hospitals
- To install and operate the Cel-Fi QUATRA in hospitals, clinics or health care facilities interference has to be considered and a suitable distance to avoid interference has to be assessed.
Explosive Environments
- Petrol stations and explosive atmospheres
- In locations with potentially explosive atmospheres, appropriate safety distances has to be assessed.
- Such areas might be classified as Ex-zones. Any part of the QUATRA signal booster installation (box, power supply, cables, antennas) should keep at least the assessed safety distance to any point of the Ex-zone.
- Areas with potentially explosive atmospheres include petrol stations, fueling areas, below decks on boats, fuel or chemical transfer or storage facilities, areas where the air contains chemicals or particles, such as grain, dust, or metal powders.
Blasting Caps Areas
- In a blasting area or in areas posted turn off “two-way radios” or “electronic devices” to avoid interfering with blasting operations appropriate safety distances has to be assessed.
05. Deploying Cel-Fi QUATRA
Planning
To facilitate the installation process and the best performance at the site, it’s important to plan the system design prior to any permanent installations.
Step 1: Site Survey
Formal Site Surveys are not required for a QUATRA installation, but some form of site survey is recommended for best results.
For QUATRA, best practices will identify and document the following items:
| # | Item | Purpose |
| 1 | Project site address | Mapping (can also view site exterior with Google Earth) |
| 2 | Operator(s) of interest Note: QUATRA 1000 systems support single carrier operation per NU/CU combo (system). QUATRA 2000 systems support two carriers per NU/CU combo (system). |
Select systems |
| 3 | Building size, floor plans, photos | Project size, interior structures/usage such as high stacked materials, cubicles etc. Suspended or open ceiling? CU mounting options (ceiling tile, wall, pole, hanger rod). |
| 4 | Note wall construction (hollow, masonry) | Interior RF propagation expectations/hardships |
| 5 | Ask customer where service is good/poor/critical | They know! And they have expectations to meet. |
| 6 | Nice to have: Measure existing service (smartphone) | Level and Quality (speed tests, and android apps such as Network Cell Info Lite). Note on floor-plans. |
| 7 | Donor options (i.e. antenna location options, measure). Outdoors best, but may be indoor if RF well isolated from CU coverage zones. | Bring quality service indoors by measuring donor signal quality where donor antennas are practical (where allowed, cable penetration available, isolated from CUs). |
| 8 | Discuss cabling route options (LAN and Coax) | Consider low coax loss to NU(s), NU placement, LAN cabling to CUs, NU internet connection and power outlet |
Step 2: Estimating Hardware Needs
Given the results of the survey process, use your preferred modeling and estimation method to generate a budgetary equipment bill of materials (BOM).
The online QUATRA BOM Estimator (QBE) is recommended and can also be used at this stage.
Step 3: Determine NU Donor (Off Air or Small Cell) Location
- If using an outdoor donor antenna:
- For sites with very weak donor signals, Donor antenna system gain (in dBi) minus coax loss should be ≥ 5 dB, for best results. If donor signals are strong, a single donor antenna may be split to feed multiple NUs (best if LTE RSRP into each NU is >= -90 dBm).
- For best results the donor antenna should have as much isolation as possible from
the other system components, in particular the CUs. - CUs should be placed at least 10 meters from any NU.
- QUATRA uses QMA connectors at the NU.
QMA-RA to N adapter kits are available from Nextivity.
Model: D12-20114-2002
Nextivity also offers a variety of other adapters specific for connectors used in the QUATRA solutions. cel-fi.com/quatra
- If using a small cell, make sure to understand the small cell’s installation requirements, provided by the small cell vendor:
- Does the small cell require external access to GPS signal?
- Is the Internet feed at the location sufficient in terms of bandwidth and availability?
- Is there sufficient space for the Small Cell Interface (SCIF) to be used?
- If using an indoor donor antenna (QUATRA 1000 only), it is recommended that the antenna be located close to the NU for best performance and minimal loss from antenna to NU.
Note: The NU+ANT should be well isolated from all CUs (walls etc.), to ensure full CU transmit power.
Step 4: NU Internet Connection & WAVE Portal Account
Network Unit requirements:
- Power
- Internet Access via LAN port
- Note: Make sure IT Staff can assist with any LAN issues if needed. A LAN Connection Guide is available on request.
- Note NU Serial number
- Located on the back of each unit
- Access to the Unit in the WAVE portal is based on the Serial Number
- Located on the back of each unit
Step 5: Coverage Unit (CU) Placement
Coverage is greater in open areas. Use the table to estimate where CUs should be placed. CUs should be ceiling mounted in open areas such as large rooms and hallway intersections.
Coverage Area Radius (estimated, meters)
| Area Type | Small Cell Mode | External Antenna Mode (Outdoor Donor) | External Antenna Mode (Indoor Donor) |
| Open Area (no general obstructions) | 24 | 24 | 20 |
| Open Area + Cubicles | 20 | 20 | 16 |
| Small Offices (framed interior walls) | 16 | 16 | 13 |
| Small Rooms (masonry interior walls) | 12 | 12 | 9 |
Note: Each CU has QMA-Female RF ports (x2). Passive antennas may be connected to these ports to provide additional coverage options. Typical passive RF cabling and antenna restrictions apply.
Step 6: Coverage Unit Cabling
Determine how many cables may be needed for the planned Coverage Units.
- Each CU requires a dedicated cable to the Network Unit
- Active Ethernet hubs such as switches or routers may not be used
- Cables must be Cat 5e or better (Gigabit compliant)
- No cable may exceed 100m (325 ft.), or 150m (492 ft.) if 22 or 23 AWG CAT6 or CAT7 is used.
- You may use one QRE per CU to extend range to 200m (650 ft.)
- OK to use existing LAN cables (rather than run new cables), if they meet the minimum requirements
Expert Tip: Check your plan against these rules
- CUs should be at least 10 meters (33 feet) away from any Network Unit
- The donor antenna should be very well isolated from all CUs (50m min; less if well separated by walls or solid structures)
Install
1. Record serial numbers by location
The QUATRA Management tools, including the WAVE Portal, will reference the NUs and CUs by serial number during commissioning.
Tip: Friendly-names may be assigned during the commissioning process.
2. Mount the hardware
Engineering Tech Note - QUATRA Cable and Connector Best Practices
Cel-Fi QUATRA uses QMA RF connectors and standard Ethernet RJ45 connectors. Proper handling
practices will help ensure optimum performance and limit potential connector strain or damage.
QMA RF Connections
Use smaller flexible coaxial cables that are easier to route and manage behind the Network or Coverage Unit. Rigid thicker cables (such as LMR400 or Helix) will not fix properly and may strain and damage the QMA connectors on the unit.
Removing A QMA Connector (Once Installed)
- Remove NU or CU from the Mounting Bracket
- If connected directly to the MIMO panel antenna you need to remove the antenna from the bracket as well or disconnect the pigtail from the N-connector side
- Disconnect power supply, and all cables from the unit
- Place the NU or CU face down on a flat surface, providing access to the QMA RF ports
- Using Both hands, gently press down the back of the QMA connector while using both index fingers to pull the outer collar of the QMA connector
- The locking mechanism will disengage and allow the connector to be safely removed
Ethernet Cables (RJ45)
Crimp on RJ45 connectors fit well behind a Network or Coverage Unit if flush mounted to a solid surface. Prefabricated cables often have large strain reliefs that can cause damage to the unit connector ports if the unit is mounted directly to the surface. To accommodate these types of cables, use adequate mounting practices such as the supplied U brackets to ensure adequate space behind the units for the cables.
Damage to the unit connectors may result if a unit is hung or dropped with a cable attached.
Cable
Route and connect all cables.
NU to CU cabling
- (Recommended) Connect CUs in order, CU1, CU2, etc.
- (Recommended) Best practices to leave a service loop in the cable, for more flexibility with mounting location. QUATRA CU connections are lossless, so there is no penalty for excess cable length if less than the maximum cable length specification.
Note: Do not power up system at this point.
- Up to four (4) NUs may be daisy-chained.
Systems continue to operate during software updates but may not be visible on the portal during the update process (usually for 30 minutes within the first 24 hours of operation).
Note: Please leave the systems connected to the Internet for at least 24 hours, or manually select Software Update from the Portal if an immediate update is desired.
Power
Power the Network Unit and Commission the System.
Important:
- Setup a LAN Connection to the WAVE Portal
- Use the WAVE Portal
- Make sure that the NU mode is properly set to Internal Antenna, External Antenna, or Small Cell using the Cel-Fi WAVE Portal (you can access your system record using the NU serial number.)
- If using a small cell, verify the small cell is commissioned and transmitting before commissioning QUATRA.
- Once a donor signal is available to the NU and CUs are connected, plug in the NU power supply.
- QUATRA will communication with the portal via the LAN connection (Internet).
- Select your new system NU serial number under New Systems (Dashboard page) and follow the guided commissioning steps.
- Complete the commissioning steps.
Note: If using an off air donor antenna, be sure to complete the Antenna Positioning Test (also available under the system asset Options menu).
Once commissioning is completed, the Cel-Fi QUATRA system should be providing service.
At this time, LEDs should be SOLID GREEN.
- If an LED is blinking GREEN, wait for the process to complete
- If an LED is RED, please see the our Troubleshooting Guide.

07. Terminology
Active DAS: A powered DAS (Distributed Antenna System) Network.
Attenuator: An electronic device that reduces the amplitude of a signal.
Cel-Fi WAVE: A cloud portal system for managing Cel-Fi systems Coverage Unit (CU). The Cel-Fi unit that broadcasts cellular service where coverage is needed (Service signal).
Donor Antenna: Receives and transmits signals with the existing cellular network.
External Antenna: Antennas external to a device and connected with RF cables.
Gain or System Gain: The amount of amplification that may be applied to the source signal.
iBwave: A solutions planner that allows you to perform complete RF distribution designs with hardware such as Cel-Fi products.
Interference: Locations usually between multiple cell sites that may be interfering with each other and reducing network capacity.
Isolation: Separating donor-service antennas to limit feedback potential.
MIMO: Multiple-Input Multiple-Output antenna scheme that improves capacity. Cel-Fi QUATRA is a 2x2 MIMO system, using two antennas per NU or CU.
Network Unit (NU): The Cel-Fi unit that connects to the existing cellular network (Donor signal).
Pilot Pollution: See Interference.
PoE (Power over Ethernet): To pass electrical power along with data on Ethernet cabling.
QMA connector: A spring loaded quick connect small-size RF connector used to join coaxial cables.
QRE (Cel-Fi QUATRA Range Extender): Allows Cel-Fi QUATRA NU to CU interconnect cable lengths to 200m.
RFoE: The transport of RF signals over Ethernet cable.
Server (also referred to as “Service”) Antenna: Receives and transmits signals amongst local user devices (phones/tablets etc).
SMA Connector: A common small (Sub-Miniature A) 50 ohm RF cable connector.
Small Cell: Low-powered cellular radio access node.
Splitter (Divider/Combiner): Splits a single coaxial cable to/from multiple cables
