Two Ethernet links are plugged into a CU (Coverage Unit) for the CEL-FI QUATRA 4000 to connect it to the NU (Network Unit). These links provide both power (via PoE) and data, enabling the CU to receive signal from the NU and distribute it locally.

    OV E RV I E W 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.
  • Page 10 Architecture Overview...
  • Page 11 Real World Examples 1. Off Air Install, 75K ft building In this example, Cel-Fi QUATRA is providing cellular coverage for four carriers in a six story 75,000 ft building. Individual LPDA antennas are located on the top of the building to ensure the best signal-to-noise ratio for all four carriers. Four coax cables are pulled through the roof to Network Unit.
  • Page 12 2. Supercell Install, 300K ft building This building did not have adequate donor signals for the four Operators, so small cells were chosen as the signal sources. 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.
  • Page 13 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.

    H A R D WA R E C O M P O N E NTS 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).
  • Page 16 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 distributed over two Category“Ethernet” cables to the Coverage Units (CU).
  • Page 17 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) •...
  • Page 18 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 4000 Coverage Unit The Coverage Unit includes a multi-band blade style antenna that can be connected directly to the CU.
  • Page 19 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). QUATRA 4000 FIBER HUB...
  • Page 20 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 up to 200 meters with Cat5e, or up to 300m if CAT6/7, 23AWG cable is used.
  • Page 21 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.
  • Page 22 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.

    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.
  • Page 26 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).
  • Page 27 3. Drill the holes for the anchors. 4. Hammer in the anchors. 5. Partially screw in the top two screws.
  • Page 28 6. Hang the unit from the top two screws, through the eye holes. Adjust the unit to level and then tighten the screws 7. Screw in the bottom two screws. 8. Mounting is complete.
  • Page 29 Connecting Donor Sources 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 • 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.
  • Page 30 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.
  • Page 31 Installing a CU Wall 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. 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.
  • Page 32 4. Drill the holes. 5. Hammer in the anchors. 6. Attach the bracket to the wall with the included screws.
  • Page 33 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.
  • Page 34 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 coaxial cable can be connected with a series of passive antennas attached. Server Antenna port Connecting NU and CU Each CU connects to the NU using two Ethernet cables (Cat5e or better).

    Diagnostics and Testing WAVE PRO and COMPASS Introduction Cel-Fi COMPASS is a hand-held battery operated device specifically designed to simplify the installation of all QUATRA variants, without the need for an Internet connection to the WAVE Portal in the cloud. Note: The WAVE Portal is a very powerful and time saving system.
  • Page 39 Cel-Fi QUATRA Installation Features Overview When it’s 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.

  • Page 41 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.
  • Page 42 Steps 1. Make sure the Cel-Fi COMPASS is connected to the donor antenna using the (included) RP-SMA to N adapter cable. 2. The SIM card in COMPASS must be removed when using this feature. 3. Click on “Antenna Positioning” in the WAVE PRO app. 4.

    Signals spread over the full bandwidth and narrow band. 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.
  • Page 47 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.
