This manual is applicable to the Cel-Fi QUATRA 4000c M/N: I44-1M34NCU 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. Nextivitys 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-Fis 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.

** CBRS Class A 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 ft2 building 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 ft2 building. 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 ft2 building 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. PVT CBRS 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. PVT CBRS Cel-Fi QUATRA 4000c Key Features Independent donor ports for each operator allows for independent antenna optimization Carrier Grade, FCC-certified Smart Signal Booster Support for AT&T, Verizon, T-Mobile and CBRS Relays two (2) bands per operator, and one (1) CBRS channel Single combined (CU) server port enables driving either a serving antenna or passive DAS field 100 dB max system gain 140MHz total relay bandwidth Support for up to six (6) CUs (twelve with a HUB) N-type RF connectors (donor and server) Up to 100m cable distance between NU and CU (using Cat5e), or 150m using 22/23AWG CAT6/7 QUATRA Range Extender (QRE) doubles CU cable length (up to 300m) 20-22 dBm uplink power per operator per band 16 dBm downlink power per cellular channel, and 20 dBm for CBRS. Internal modem for remote management (SIM slot access) Industrial aluminum powder-coated housing Cel-Fi QUATRA 4000c Service Agreement Every NU will be bundled with a 1-year product Service Agreement The Service Agreement may be renewed on an annual basis The Service Agreement includes a 1-year SIM service plan, if you chose to use the internal modem for your WAVE Portal connection. Upon request once the system installation is complete, Nextivity will review key system KPI's and provide feedback on the installation. Nextivity will monitor systems for any alarms and perform Level 1 remote troubleshooting for each alarm. Learn more about our Service Agreement. 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). QUATRA 4000c Network Unit 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 units internal cellular modem, and the other is for GPS. (The GPS port is for future functionality) Power AC Power Supply (inside the NU) AC power cord Physical Interface RJ45 ports (13) Twelve RJ45 ports (2 for each of the 6 CUs) One LAN port for remote management SFP+ module dock (for use with a Fiber HUB) N-type Female RF Ports (4) for Donor Antennas One for each carrier SMA ports (2 for the internal LTE modem) User Interface LED interface (front) to indicate system status. (For detail on the LED go to LEDs.) Power CU1 CU2 CU3 CU4 CU5 CU6 SFP+

LAN MODEM 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. QUATRA 4000c Coverage Unit Accessories QUATRA 4000 FIBER HUB Model Number: Q40-1234FNU The HUB functions much like an NU, except it does not have donor antenna ports. It connects to an NU over optical fiber cable (up to 2km) using SFP+ modules, and it adds up to six more CUs to an NU (twelve CUs total). Please note that the QUATRA 4000 HUB works with the Q4000, 4000i, and 4000c models. QUATRA 4000 FIBER HUB QUATRA 4000 Range Extender and Fiber Range Extender The QUATRA Range Extender (QRE) unit is a device that extends the standard 100 meter Ethernet cable length from NU to CU up to 200 meters with Cat5e, or up to 300m if CAT6/7, 23AWG cable is used. 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). Traditional Ethernet extenders will not work with QUATRA. The QUATRA Fiber Range Extender (fQRE) system is a similar pair of devices that convert QUATRA 4000 specific signaling to optical fiber and then back to Ethernet for up to an additional 2km of CU cable length. Please note that the QUATRA 4000 QRE and fQRE both work with the Q4000, 4000i, and 4000c models. Donor Antennas 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-V44-201 Cel-Fi LPDA-R Antenna Nextivity recommends its LPDA-R antenna for use as a great donor antenna for most situations. Learn more about our Antenna options. Server Antenna The server antenna connects to the RF port on the CU. Server Antenna port A variety of Server antennas are available from Nextivity. Visit the Antenna Product page for details and updates. Couplers RF couplers or tappers may be used with Coverage Units when multiple service antennas are desired. Careful system design should be implemented to insure sufficient power levels into all antennas. The WAVE Portal Introduction The WAVE Portal is Nextivitys SOC2 Type 1 compliant cloud-based software platform from which Cel-Fi apps and connected devices are hosted and driven. Current-generation Cel-Fi products feature embedded connectivity that allows them to connect to the WAVE cloud. The WAVE portal and apps are used to facilitate software updates, registration, commissioning, installation, optimization, and troubleshooting. The Cel-Fi WAVE platform continues to expand in features and function. In order to use the WAVE portal and related capabilities, you must be registered with the system. Request access to the WAVE Portal Login to the WAVE Portal The portal constantly monitors your systems and tells you how to resolve alarms or improve performance with explicit guidance, all from your smartphone or computer browser. See Cel-Fi training modules for easy to understand video and slide tutorials. Connecting your 4000c to the WAVE Portal There are two ways to connect the NU to the cloud. With either method, you should see your system on the portal by its NU serial number once it is connected using either method below, and powered on. If you do not see your NU on the portal (New Systems page or Systems page), then you need to register it with your portal login account. Click on the portal Access tab (lower left portal screen), and select the Request Access option under the upper right screen Options menu. Input the NU serial number and the SKU from the NU carton label, and access is immediately granted. If the NU carton has been discarded, contact your point of sale or Nextivity Support to obtain access. LAN Connection Method:

The first method is by connecting a LAN Ethernet cable to the LAN port on the NU, and setting the LAN firewall settings as described in the settings guide. The LAN LED should be solid green, or blinking green to indicate traffic. You may also test the firewall settings using the WAVE Field Tool Windows program. Learn More about LAN Firewall Settings WAVE Field Tool MODEM Connection Method:

The second method is to use the preconfigured LTE modem that is built into the NU (this requires that no Ethernet cable is connected to the NU LAN port). Screw on the provided SMA cellular antenna onto the CELL modem port located on the top center of the NU, or use a coupler to tap into the RF of a donor port cable. Note that the GPS port is currently unused and no GPS antenna is required. Next, find the pre-provisioned SIM card that came with the NU and carefully insert it in the SIM card slot next to the CELL SMA antenna port. Your SIM card may have been factory inserted (if so you will see the SIM card in the slot). Damage may result if the card is pressed into the slot with excessive force. In this modem mode, the LAN LED should of OFF and the MODEM LED should blink Green-red to indicate normal operation. Alarms, Alerts, and Policies Cel-Fi systems support a variety of standard alarm conditions. Policies are your own account lists of alarms, alarm severities, and whether you want them displayed on the portal (console), or emailed or texted to individuals or groups. Each new user (company) is given a Default Policy with the basic alarms already in it. You may edit this policy as you please, or create new policies. For example, you may want different policies for different regions. It is the responsibility of policy holders to add new alarms that may be introduced with new products. It is recommended that all of your policies have all possible alarms, so they can properly report alarms for all products where alarm options may differ. Current alarms and the last 100 alarms history are displayed on the Systems page for each installed system. For a universal alarms page of all alarms across all systems you have access to, please refer to the Notifications tab. For information on how to resolve any alarm, simply select the alarm notification in the Alarm History window. Below is a non-exhaustive list of basic alarm categories.

Installation 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. Overview Several things need to be determined as part of installation planning and preparation. Perform indoor and outdoor signal surveys to understand current signal problems and to assess candidate donor antenna locations (the Nextivity COMPASS signal survey tool is purpose-built for survey activities) Determine where the NU(s) will be mounted Ensure an adequate power source (outlet) Determine donor signal sources and cabling/routing Determine CU cabling/routing pathways (Low-voltage/Ethernet routing rules) 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: For signal surveys, or to find candidate locations for donor antennas, we recommend Nextivitys COMPASS XR tool. Ask your distributor for more information or visit us at www.cel-fi.com Note: IBWAVE or the Nextivitys BOM Estimator design tool (or other RF planning tools) are not required but are a good way to ensure the best performance outcomes. iBwave vex and template files may be found on the Nextivity product pages. BOM Estimator Tool Installing the NU Mounting The Cel-Fi QUATRA NU is designed for simple wall mounting, typically in an IT room with coaxial cable access to donor antennas that are installed on the roof, or any other exterior location with a quality donor signal from each cellular operator. The location should also have an available electrical outlet within reach of the supplied power cord. Mounting accessories, including screws and anchors, for common material types (drywall, plywood, etc) are included with each NU. Equipment Required for Mounting Drill Drill bit extender (3+) Hammer Pencil, or other similar marker Level Caution: Make sure the area behind any surface is free of electrical wires or other dangerous elements prior to drilling. The QUATRA 4000c 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 Sources The QUATRA 4000c has four independent RF ports for connecting the donor signals. Each port:

Is an N-type Female connector Is specific to the supported carrier Is designed to support a variety of band configurations Cellular Donor Antenna Input The three carrier RF ports can be fed by a donor signal consisting of either a small cell or an antenna. The PVT

(CBRS) port must be fed by a CBRS small cell (CBSD). 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. A signal-

to-noise ratio (SiNR) of > 5 dB is strongly recommended for each given carriers source signal, however lower quality signals will work if that is all that is available for the site. Better SiNR leads to better throughput and bars of signal strength on cellphones. 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 NUs RF port for each given carrier. Please watch our donor antenna best practices video by clicking on the link below. This video and many other videos and webinars may be found under the Webinars link at the bottom of www.cel-fi.com https://www.cel-fi.com/casestudy/cel-fi-quatra-antenna-selection/

Cellular Small Cell Donor Input If a small cell is used as the donor source then it should be connected at this time. The recommended input signal level for a small cell, after connection losses and attenuation, should be between -75 and -95 dBm RSRP into the NU donor port for that operator. It is easy to verify this power level using the Radio Data page on the WAVE portal once the system is operational. Note: For more information about connecting small cells, see the QUATRA Approved Small Cell Guide. Private Network (PVT) CBRS LTE Donor Input QUATRA 4000c is also capable of providing service for an in-building Private LTE network. CBRS is more secure with better mobility, latency stability and quality than Wi-Fi. It is designed to spur innovation in connectivity and IoT applications. It occupies 150MHz of shared spectrum in the 3.5 GHz C-band, also known as Band 48 (B48). To enable this port and explore CBRS private network options, please contact Nextivity or your point of sale. Connecting your 4000c to the WAVE Portal (cloud NMS) There are two ways to connect the NU to the cloud. With either method, you should see your system on the portal by its NU serial number once it is connected using either method below, and powered on. LAN Connection Method:

The first method is by connecting a LAN Ethernet cable to the LAN port on the NU, and setting the LAN firewall settings as described in the settings guide (see the link below). Once the NU is powered ON, the NU will automatically reach out to the WAVE Portal in the cloud and the LAN LED should be solid green, or blinking green to indicate traffic. If you do not see your NU on the portal within ten minutes of powering up the NU (New Systems page or Systems page), then you need to register it with your portal login account. Click on the portal Access tab (lower left portal screen), and select the Request Access option under the upper right screen Options menu. Input the NU serial number and the SKU from the NU carton label, and access is immediately granted. If the NU carton has been discarded, contact your point of sale or Nextivity Support to obtain access. If you still are unable to see your NU on the portal, you may use the WAVE Field Tool link below to test the portal firewall connection using a Windows 10 or later PC. This tool has many features, and the connection test emulates the NU connection to test your firewall. Learn More about LAN Firewall Settings WAVE Field Tool Internal Modem Connection Method:

The second method uses the internal LTE modem built into the top center of the Network Unit. You will notice two SMA connectors. Please locate the small SMA antenna that came with your NU and attach it so the CELL SMA port on the top of the NU. The GPS SMA port remains unconnected and is for future use. A SIM card with one year of prepaid service should be pre-installed in the SIM card slot. If you do not see a SIM card in the slot, then locate it in your product packaging and carefully insert the SIM into the slot as indicated on the housing. Do not force the card into the slot or damage may result. This SIM is paired with QAUTRA and will not work in other devices. If you do not see your NU on the portal within ten minutes of powering up the NU (on the New Systems page or Systems page), then you need to register it with your portal login account. Click on the portal Access tab

(lower left portal screen), and select the Request Access option under the upper right screen Options menu. Input the NU serial number and the SKU from the NU carton label, and access is immediately granted. If the NU carton has been discarded, contact your point of sale or Nextivity Support to obtain access. Once the NU is powered ON, the NU modem will automatically reach out to the WAVE Portal in the cloud and the MODEM LED should blink red-green to indicate a successful cellular connection. If you do not have a viable cellular signal at the NU location, you may remove the SMA antenna from the CELL port and connect the CELL modem port to one of the donor antenna feeds using an RF coupler. Power The QUATRA 4000c 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 before the system is powered-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 CUs Wall Mounting The Coverage Unit (CU) comes with a wall mounting bracket in the box. To mount the QUATRA 4000c CU simply follow these steps:

1. Determine the 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 4000c 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 both Locking Screws to ensure the CU is securely attached to the mounting bracket. The CU may also be mounted to many surfaces with appropriate Unistrut hardware. 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 may be used, or a coaxial cable can be connected with a series of passive antennas attached. Connecting Server Antenna or Cable Connecting NU and CUs Each CU connects to the NU using two category cables (Cat5e or better). QUATRA signaling is not Ethernet compatible, so routers, switches, bridges or other active Ethernet devices may not be used. Patch panels or punch-down blocks may be used. CU port assignment on the NU Follow general category cable routing practices as follows. The system constantly monitors all CU cables and a red LED means that the NU cannot communicate with a CU properly. General CU Cabling Rules:

QUATRA uses category cables, commonly used as Ethernet cable. However, QUATRA cables are NOT ETHERNET/LAN COMPATIBLE!

CU cables must pass 1000BaseT (gigabit). CU cables may pass through patch panels, but not active equipment such as routers or switches that will not understand QUATRA signaling. CU cables should follow normal low voltage cable pathways. Do not run CU cables alongside AC power lines or other sources of interference such as LED lighting. Crossing power lines at 90 degrees is OK. Only a QUATRA Extender may be used to extend a CU cable in length. Off-the-shelf Ethernet Extenders or Fiber interfaces will not work. Install the QRE halfway along the cable. CU cable lengths up to 150 meters (150m+150m with a QRE) are possible with thicker gauge 22/23 Category cables. ONLY USE PURE COPPER CATEGORY CABLES. CCA (Copper Clad Aluminum) is not suitable for PoE applications. Troubleshooting:

Check that each CU cabling rule has been satisfied. Debris in the port blow off the connector/port and insert the connector a few times to clean the contacts. Test the port on the NU or CU to see if there is movement. If there is any movement then the port may be damaged. Plug the CU directly into the NU using a short known good machine-made Category cable to determine if the hardware or cabling is at fault. Redo the terminators on either end of the cable in alarm. Consider punch-down Ethernet Surface Mount Boxes to remove the human cable termination component. This is more in line with standard IT practices that favor screw or punch-down terminations and machine-made cables. They are more reliable and end-point machine made jumpers are easily swapped out if they fault. Check that the RJ45 terminators are correct for the cable used (cable diameter spec for example). Using a QRE If category cable lengths greater than 100 meters from NU to CU are required (150m if using 22/23 AWG CAT6/7 cable), a QUATRA RANGE EXTENDER (QRE-4K) may be used in the middle of the cable run to achieve lengths up to 300m. If even longer CU cables are required, use the QUATRA Fiber QRE for up to an additional 2km of cable length. 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 4000c. LEDs NU The QUATRA 4000c NU has ten (10) LEDs on the front of the unit, used as status indicators, during setup and normal operation. The LEDs are labeled. NU LEDs The LEDs on the front of the QUATRA 4000c function as follows:

With regard to 4G or 5G, 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 4000c, 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 4000c. Antenna Selection There are a few considerations to make when determining the donor antenna. 1. 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. 2. 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 noise and improve SINR. 3. How strong is the serving signal? Although Cel-Fi QUATRA 4000c has the highest gain of any system 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 4000c are encouraged to follow the lightning protection guidelines documented in the National Electrical Code (NEC) and NFPA 780, and/or local codes. Server Antennas The QUATRA 4000c 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. Antenna Selection 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 360 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 in a particular direction. 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 a wall. Nextivity has a few different panel antenna options, with different levels of gain and directivity. Mounting (Coverage Unit) Drop Ceiling The QUATRA 4000c Coverage Unit is fitted with two -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) -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 4000c Coverage Unit is plenum rated.

Troubleshooting Alarm Error Description 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 Coverage Unit Hardware Error Donor Signal Too Strong 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. Troubleshoot any Network Unit (NU) error first, and check for software updates. Make sure Coverage Unit (CU) cables do not exceed recommended cable length maximums. 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. 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 Too Far 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). 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. CU Shutdown from Portal CU's 1 though 4 has been shut down from the Portal.
