4.10 Install Equipment at Final Location
Installing the eNB should be performed only by qualified installation technicians following the operator’s network design plan and according to industry standard safety precautions. Installation on a wall, roof, tower, or other structure may require a tower crew. Follow standard safety precautions for working at the expected height and as required for electrical installations. Always wear proper tower climbing safety gear and follow tower climbing safety certification rules.
This section provides guidance on positioning the equipment on a wall or using a pole-mount to place the equipment on a tower, roof, or other structure. Note that it does not matter if the eNB or the antenna is installed first (or together at the same time).
29
Review the GPS positioning guidance in section 4.10.1 and the grounding protection information in section 4.10.2 prior to beginning the installation at the final location. After that, proceed to section 4.10.3 if you are installing the eNB on a wall, or to section 4.10.4 if you are installing the eNB on a tower or other structure via pole mount.
4.10.1 GPS Positioning Considerations
Consider the following concerning GPS antenna positioning when installing the eNB.
The GPS antenna should be free of any major blocking from buildings in the vicinity. Make sure the space atop within 90 degrees (at least 45 degrees in the south) is not blocked by any buildings.
Avoid installing the GPS near other transmitting and receiving devices. The GPS should be at least 3 feet (.9 meters) from other transmitting devices.
Avoid placing any metal items within 4.9 feet (1.5 meters) of the lightning arrester.
The GPS antenna should be installed within 45 degrees to the lightning rod.
When installing multiple GPS antennas, each antenna should be separated by 6.6 feet (2 meters) above the previous one.
The GPS antenna mounting bracket and pole must be grounded.
4.10.2 Grounding Protection
The grounding terminal is a screw beside the antenna feeder interface, as shown in Figure 4-17. One end of the ground wire connects to the grounding terminal on the eNB. The other end connects to the outdoor ground point. The connection needs to be tin-soldered. Refer to grounding guidelines in section 3.9.
Figure 4-17: Grounding Protection
30
4.10.3 Install eNB and RF Antenna
Keep the RF cable length between the eNB and antenna as short as possible to minimize signal attenuation. Typically, the eNB will be located within a few feet/meters from the antenna. Only one antenna may be connected to a single Nova-243 eNB.
Operators can use an omnidirectional (“omni”) antenna or a directional antenna with the Baicells eNB. An omni antenna covers a full 360 degrees, while a directional antenna radiates in a specific direction based on angle (e.g., 45°, 90°, etc).
Note: Baicells does not manufacture antenna components; please refer to the list of distributors on the Baicells website: https://na.Baicells.com/where-to-buy/. Make sure to match the frequency range of the antenna with the eNB, and consult the regulatory rules concerning output power specific to your location.
This section explains how to install an omni or directional antenna on an outdoor structure.
For an omni installation refer to section 4.10.3.1. For a directional antenna installation, refer to section 4.10.3.2 (tower, pole). Additional information concerning roof installations is provided in section 4.10.3.3 (roof).
4.10.3.1 Install Omnidirectional Antenna
Following are guidelines for installing an omnidirectional antenna at the cell site.
• The mounting pole diameter must be between 1.4 inches to 2 inches (35 to 50 millimeters). Typically, operators use a 2-inch/50-mm round, steel-made pole.
• The top of the pole and the clamp beneath the antenna should be at the same level once the omni is installed on the pole.
• For optimal performance, ensure the omni antenna is precisely vertical.
• The top of the antenna should fall within the 45-degrees safety angle towards the lightning rod.
• There should be no metal objects within 3.3 feet (1 meter) of the omni antenna. Use an independent lightning rod that is high enough to keep all antennas under its protection cover.
• Ensure the antenna is high enough to meet the coverage requirements specified in the operator’s network design plan.
If it is not possible to install an independent lightning rod due to environmental limitations, ensure that the pole supporting the lightning rod is at least 3.3 feet (1 meter) away from the omni antenna. Follow standard transport procedures to hoist the antenna to the target location.
Once the antenna and eNB unit are installed securely in the proper position, verify grounding and lightning protection. Apply waterproofing as explained in section 4.10.6 of this document.

4.10.3.2 Install Directional Antenna on Tower
Following are guidelines for installing a directional antenna at the cell site.
• First, assemble the antenna and the upper and lower racks, as shown in Figure 4-18.
• Follow standard transport procedures to hoist the antenna to the target location.
• Using expansion screws, fix the support pole vertically to the ground (or concrete pillars on a rooftop), and fasten it with steel wires.
• Mount the antenna assembly onto the pole using the installation racks.
Figure 4-18: Assemble Directional Antenna
Once the antenna and eNB are installed securely in the proper position, verify grounding and lightning protection. Apply waterproofing as explained in section 4.10.6 of this document.
4.10.3.3 Install Directional Antenna on Rooftop
When installing a directional antenna on a rooftop, it is easier to install if the antenna andeNB are first attached to a mounting pole that will then be installed on the roof. Begin by wiring the lightning arrester on the top of the mounting pole. Next, install the directional antenna and eNB on the mounting pole with the provided supports. Ensure the directional antenna is vertically plumb with the proper down tilt for desired antenna propagation, as specified in the operator’s network design plan.
In situations where there is a wainscot on the roof and it is taller than 3.9 feet (1.2 meters), attach the fixed mounting pole and antenna on the wall with expansion screws. If the wainscot is less than 3.9 feet (1.2 meters) tall, fix the mounting pole to the wall with expansion screws and attach the base of the mounting pole to an adequate base support frame to stabilize the mounting pole.
32
If the roof does not have a wainscot, use expansion screws to fix the antenna mount on an adequate base support frame, such as concrete, or properly weight the frame to eliminate wind movement. Use guy wires to further stabilize the mounting pole.
Once the antenna and eNB are installed securely in the proper position, verify grounding and lightning protection. Apply waterproofing as explained in section 4.10.6 of this document.
4.10.4 Check eNB Status in Software
The Baicells eNB is designed to be plug-and-play and, therefore, arrives pre-configured. Before you seal and weatherproof the connections on the eNB elements, you will need to log in either to the client GUI or the cloud-based OMC to ensure the eNB status is reported as active. Section 4.10.4.1 explains how to check status using the eNB GUI. Section 4.10.4.2 explains how to check status using the OMC.
4.10.4.1 eNB GUI
To use the eNB GUI, from the eNB MGMT port, type in http://192.168.1.1, using username admin, password admin. (Once the application is installed and has a WAN IP address assigned, you can log in with http://x.x.x.x.)
Go to Status Info as shown in Figure 4-19. If the status is not reported as active, contact Baicells support.

4.10.5 Verify Lightning and Grounding Protection
Ensure that all equipment lightning protection and grounding protection measures have been taken. Information about the protection measures is covered in section 3.9 “Grounding and Lightning Protection” and section 4.10.2 “Grounding Protection”. All protection points should be inspected before proceeding to weatherproof the connections.
4.10.6 Weatherproof all Connections
Once testing is completed successfully, you will need to seal and weatherproof the connection points by wrapping them with all-weather electrical tape and mastic tape, as illustrated in Figure 4-22. At least 3 layers of tape are needed, making sure that the wrapping direction of the last layer is from the bottom up. The last layer should be tight enough to keep from cracking.
