1. Product Overview 1.1 Introduction JRL-113BT48 is an advanced two-carrier outdoor eNodeB based on LTE TDD technology. It is capable of operating in Carrier Aggregation (CA) or Dual Carrier (DC) mode. In CA mode, contiguous or non-contiguous channels are aggregated to provide up to 40 MHz bandwidth. This essentially doubles the downlink capacity with optional software and CAT6/7 user equipment.
monitoring and maintenance. 1.3 Appearance The JRL-113BT48 base station appearance is shown in Figure 1-1. Figure 1-1 JRL-113BT48 Appearance The JRL-113BT48 interfaces are described in Table 1-1. Table 1-1 JRL-113BT48 Interface Description Interface Description PWR +54V (+40V to +57V) DC power interface, typical input DC voltage is 54VDC GPS External GPS antenna, N-female connector. ANT0 External antenna 0, N-female connector. ANT1 External antenna 1, N-female connector.

2. Installation Preparation 2.1 Support Materials In addition to industry standard tools, you will need the materials described in Table 2-1 during the installation. When selecting an RF antenna, be sure to match the frequency range of the antenna with the eNB. Table 2-1 Support Materials Item Description Power cord The diameter of power cable must be AWG15 or greater (such as AWG14). And the length from the power adaptor’s DC end to the eNB must be shorter than 100 meters (~109 yards).
2.3 Installation Environment In addition to network planning, when determining where to place the eNB you need to consider factors such as climate, hydrology, geology, the possibility of earthquakes, reliable electric power, and transportation access. Avoid locating the eNB in areas where there may be extreme temperatures, harmful gases, unstable voltages, volatile vibrations, loud noises, flames, explosives, or electromagnetic interference (e.g., large radar stations, transformer substations).
1. Insert the cable into the cold shrink tube. 2. Tighten the connector. 3. Push the cold shrink tube to the top joint, and pull out the strip. 4. Ensure the cold shrink tube is tightly fitted with the connection.
3. Installation 3.1 Overview Figure 3-1 provides an overview of the installation process. Figure 3-1 Installation Process 3.2 Install GPS Antenna Read the following GPS antenna installation requirements before installing it on the eNB. No major blocking from buildings in the vicinity. Make sure the space atop is at least 45 degrees unblocked by any buildings. Avoid installing the GPS antenna in the vicinity of any other transmitting and receiving devices, to avoid interference.
NOTE: The eNB may adopt different models of GPS antenna, so the GPS antenna may not the same as above figure. But the installation steps that fix it on the eNB is the same. 3.3 Install on Pole The eNB mounting bracket is assembled in manufacturing before packing. The only action required by the installer is to fix the assembly on the pole. Check to ensure the diameter of the pole is in the range of 1.6-3.9 inches (40-100 mm).
4. Tighten two screws on the top of the bracket to complete the installation. 5. Proceed to “3.5 Connect Cable”. 3.4 Install on Wall Ensure that the wall can bear at least 4 times the weight of the eNB. The wall should be made of bricks or concrete, and concrete is recommended. Follow the steps below to install the JRL-113BT48 eNB on the wall. 1. Take apart the assembled installation bracket kit to get the installation bracket. 2.
3. Drill two .4in/10mm diameter by 2.8in/70mm deep holes in the wall at the marked locations. 4. Insert the expansion screws and fasten. 5. Check the up/down direction of the installation bracket, and then fix it to the wall with expansion screws on wall. 6. Refer to pole installation steps, fix the eNB on the wall bracket. 7. Proceed to “3.5 Connect Cable”. 3.5 Connect Cable 3.5.1 Cable Laying Requirements General requirements: Bending radius of feeder cable: 7/8” > 250mm, 4/5” > 380mm.
Avoid pulling and weighing down the optical fiber. The redundant optical fiber must enwind the dedicated device. Grounding laying requirements: The grounding cable must connect to the grounding point. The grounding cable must be separate with the signal cables, of enough distance to avoid signal interference. 3.5.2 Connect GPS Antenna 1. Insert the GPS jumper into a cold shrink tube. 2. Connect one end of the GPS jumper to the GPS antenna. 3.
The redundant fiber should enwind neatly. 3.5.5 Connect Ethernet Cable 1. Connect the Ethernet cable to ETH interface in the wiring cavity. 2. Lay the Ethernet cable along the wire groove, and stretch out the wiring cavity from ETH hole. 3.5.6 Connect Power Core The eNB uses AC-DC adaptor to convert AC power (90-264 VAC) to 48VDC power, and a surge arrester is also used for protection, as shown in Figure 3-3. Figure 3-3 Power Core Connection Relation 1.
The double hole lug must satisfy the UL standard. The diameter of the grounding cable must be AWG15 or greater. The JRL-113BT48 has two grounding screws located on the bottom of the unit, as shown in Figure 3-4. Follow the steps below the figure to connect the ground cable. Figure 3-4 Grounding Screws 1. Unscrew one grounding screw, connect one end of the ground cable to the grounding screw, and fasten it again. 2. Repeat step 1 for the second grounding screw. 3.
Appendix A Regulatory Compliance FCC Compliance This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Any Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.
