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).
Page 5 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.
Page 6 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.
Page 7 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.

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).
Page 10 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”...
Page 11 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.
Page 12 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).
Page 13 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.

Page 22 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.
Page 23 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.
Page 24 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).
Page 25 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.
Page 26 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.
