This manual is applicable to the Cel-Fi QUATRA 4000 ONLY, and does not apply to any other QUATRA variants. Use Cel-Fi QUATRA 4000 indoors. It should not be used outdoors. These products are designed to be used with the 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. Introduction to QUATRA 4000 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 signal 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, Cel-Fi 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 Cel-Fi 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. 5 12/6/2019 6 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-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. 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 Uplink muting, when handsets (UE) are not detected Signal qualification (channels are individually qualified, so noise or very poor signals wont be amplified and degrade the network) The Cel-Fi WAVE Platform cloud-based portal enables an operator to monitor equipment and network KPIs, such as channel configurations, RSRP, RSCP, SINR, and system gains, providing control and optimization insight. Regulatory // Model Number: Cel-Fi QUATRA 4000 The QUATRA 4000 is FCC Part 20 certified. It supports bands 4,5,12,13 and 25. 12/6/2019 7 Bands Supported Under This FCC Certification Verizon Band 4, 13 and 25 Sprint Support Band 2, 25 AT&T Support Band 4, 5, 12, 25 T-Mobile Support Band 4, 12, 25 12/6/2019 System Overview 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 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. Architecture Overview Figure 1.

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. 12/6/2019 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 Figure 2. NU Image 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). 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.

Service can be deployed through a single connected antenna, or through a DAS field. Figure 4. QUATRA 4000 CU The Coverage Unit includes a multiband blade-style antenna that can be connected directly to the CU. See Figure 8. CU Antenna Figure 5. CU Antenna 12 12/6/2019 Figure 6. CU Server Antenna Accessories QUATRA 4000 Range Extender (QRE4K) Model Number: Q40-OE Figure 7. QRE-4K 13 12/6/2019 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). Figure 8. Using QRE-4K 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. Figure 9. Donor Antenna Connection Cel-Fi LPDA-R Antenna Model Number: A62-V44-200 14 12/6/2019 Nextivity recommends its LPDA-R antenna for use as a great donor antenna for most situations. Figure 10. Cel-Fi LPDA-R antenna Check www.cel-fi.com/antennas for details and updates. Server Antenna The server antenna connects to the RF port on the CU. Figure 11. Server Antenna Connects A variety of Server antennas are available from Nextivity. Check www.cel-fi.com/antennas for updates. Couplers RF couplers or tappers can be used in conjunction with the Cel-Fi QUATRA 4000 and 4000i, when multiple antennas are required for the installation. Careful system design should be implemented to insure sufficient power levels into all antennas. 15 12/6/2019 The WAVE Portal Introduction Cel-Fi WAVE is Nextivitys SOC2 Type 1 compliant cloud-based software platform from which Cel-Fi apps and connected capabilities are hosted and driven.

User Profile is where individual account information is stored, as well as any Group assignments. 17 12/6/2019 Installation Overview 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 isnt 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. o Ensure adequate power source. o Determine donor signal sources and cabling/routing. o 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. o Determine if the (included) Mini Panel Antenna will be used or a DAS field, for each CU. o 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. NU Mounting 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. An NU Mounting Template is included in the NU box. The QUATRA 4000 NU Mounting Template can also be downloaded from www.cel-fi.com/QUATRA4000. Equipment Required for Mounting Drill Drill bit extender (3+) Hammer Pencil, or other similar marker. Level 18 12/6/2019 Caution: Make sure the area behind any surface is free of electrical wires or other dangerous elements prior to drilling. Figure 12. NU Mounting Illustration 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). Option 1. Using the NU Mounting Template Use the mounting template included in the QUATRA 4000 NU box. 19 12/6/2019 Figure 13, NU Mounting Template Option 2. No Template 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. Using a drill, drill the location for the wall anchor. 4. Hammer in the wall anchor. 5. Place the NU in the right location and screw on the mount. 6. Make the unit as level as possible, and mark the spot for the other top mounting hole on the wall. 7. Using the drill, drill the appropriate hole where marked. 8. Hammer in the anchor, appropriately. 9. Screw in the second NU tab. 20 12/6/2019 Note: The keyhole style allows for fine-tuning of the horizontal level. Figure 14. Leveling the NU 10. With the NU attached to wall, drill holes for each remaining anchor. 11. Unscrew the top two screws slightly, so the unit can be removed, but leave the screws in the wall. 12. Remove the NU from the wall and hammer the bottom two drywall anchors into place. 13. Hang the NU back on the top two screws and re-tighten those screws. 14. Screw the bottom two screws into place, through each bottom tab hole. The unit should now be firmly attached to the wall. 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 Donor Antenna 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 >0dBm is strongly recommended for each given carriers source signal. Better SiNR leads to better throughput. 21 12/6/2019 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. 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. Power 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. Figure 15. NU Power Cord 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. CU Mounting The Coverage Unit (CU) comes with a wall mounting bracket in the box. To mount the QUATRA 4000 CU simply follow these steps:

1. Position the QUATRA 4000 CU wall mount on the wall in the desired 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. Holding the mounting bracket in place, mark hole locations with a pencil. 3. Drill the holes. 22 12/6/2019 4. Hammer in the anchors. 5. Attach the bracket to the wall with the included screws. 6. Once the bracket is firmly attached to the wall, the CU can be attached to the bracket. Figure 16. Attach CU to bracket 7. With the bracket in place, attach the CU. 8. Tighten (finger) each Locking Screw into place to ensure the CU is securely attached. 23 12/6/2019 Connecting Server Antenna(s) Figure 17. Attaching antenna to CU 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. 24 12/6/2019 Connecting NU and CU Each CU connects to the NU using two Ethernet cables (Cat5e or better). Figure 18. 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 may be used. The QUATRA 1000 and QUATRA 2000 QRE is not compatible with the QUATRA 4000. LEDs NU 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. The LEDs on the front of the QUATRA 4000 function as follows:

NOTE: The WAVE Portal is a very powerful and time saving system. Nextivity highly recommends that you still connect your QUATRA systems to the Internet for WAVE Portal remote management, alarms, and diagnostics.Note: COMPASS has its own User Manual. Included here are only those items that relate specifically to the QUATRA 4000. CEL-FI QUATRA INSTALLATION FEATURES Figure 19. QR Code for WAVE PRO Overview When its not possible to open a LAN connection between a Cel-Fi QUATRA Network Unit (the NU) and the Cel-

Fi WAVE Portal, these features will help installers setup Cel-Fi systems quickly and efficiently. While complete provisioning and optimization using the WAVE Portal is preferred, we understand that it's not always possible. Note: Many features in the WAVE Portal are not available when using this tool. These include Commissioning, Operator Configuration, feature settings such as disable software updates and access to key performance data used in remote management. Updating QUATRA Software From time to time, the QUATRA 4000 firmware will be updated for feature improvements and bug fixes. Updating QUATRA 4000 firmware can be accomplished in either of two ways:

1. Using WAVE PRO a. Launch the WAVE PRO app. b. Connect the LAN port on the QUATRAs NU to an active Ethernet LAN. c. Initiate the update from the Systems page Options menu. i.

Click on Bands Settings b. Select the band preference and then click Update Step 1 Step 2 29 12/6/2019 CEL-FI QUATRA OPTIMIZATION FEATURES Antenna Positioning 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. 1. Make sure the Cel-Fi COMPASS is connected to the donor antenna using the (included) SMA to N adaptor. 2. Click on Antenna Positioning in the WAVE PRO app. 3. 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. 4. The app will show the recommended band to use.

Step 1 Step 2 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. Fig. X Serving Cell Report 31 12/6/2019 Donor Antennas Advanced Information. Antennas and QUATRA 4000 Donor Signals 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. 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 a 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 signal. 32 12/6/2019 3. 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. Server Antennas 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. 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. 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) Drop Ceiling The QUATRA 4000 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. 33 12/6/2019 Note: The Cel-Fi QUATRA 4000 Coverage Unit is plenum rated. 34 12/6/2019 Specifications OPERATORS CONFIGURATIONS OPERATORS Operators Supported Bands: QUATRA 4000i (Part QUATRA 4000 AT&T, Sprint, Verizon, T-
