station that enables wired and wireless broadband access to Long-Term Evolution (LTE) backbone networks using Time Division Duplexing (TDD) technology (Figure 1-1). Figure 1-1: Nova-243 eNB The eNB is a component of the operator’s cell site and includes an integrated Global Positioning System (GPS). Optionally, the operator may install external GPS antennas with each eNB. The operator selects and provides one omni or directional Radio Frequency (RF) antenna to install with each eNB. Each eNB comes pre-configured so that installation is simplified and connection to the core network is plug-and-play. Baicells provides operators with local and Web-based Graphical User Interface (GUI) applications to configure and manage individual eNBs and Customer Premise Equipment (CPE). Additionally, Baicells offers a Software-as-a-Service (SAAS) solution called CloudCore. CloudCore, also referred to as BaiCloud, handles the LTE Evolved Packet Core (EPC) network functions (Figure 1-2) and provides operators an account to use the Operations Management Console (OMC) for managing multiple sites across the network and the Business and Operations Support System (BOSS) for subscriber management. NOTE: Local, private network versions of EPC and OMC+BOSS are also available. For information on these options, please contact your Baicells sales representative.

2.1 Personnel & Network Design Installation personnel should follow standard, industry safety precautions when installing a Baicells Nova-243 eNB. Installers should refer to the operator’s network design plan for information about specific network components, RF coverage goals for the specific cell site, IP addressing, and configuration settings. Before installing, clearly identify the structure on which the eNB equipment will be installed, the intended height where the antenna and eNB will be located, the degree of antenna down tilt, and other necessary specifications that may impact the success of the installation. Consult regulatory rules concerning output power limits specific to your region. 2.2 Cables When determining which RF antenna to use, be sure to match the frequency range of the antenna with the supported frequency range of the eNB. In addition to standard tools, refer to Table 2-1 for cables and wire required for eNB installation. The cables are available through Baicells suppliers. Table 2-1: Materials Item Description Power Cable Gauge: Less than AWG16 (e.g., AWG14) Length: Shorter than 1150 feet (350.5 meters) Ethernet Cable Outdoor CAT6 cable Shorter than 330 feet (100.6 meters) RF Antenna Feeder Cable 50 ohm RF Antenna Omnidirectional or Directional antenna Maximum 1 antenna per Nova-243 eNB Ground Wire 16mm² diameter yellow-green wire GPS Antenna GPS antenna with N-type cable and GPS mounting bracket 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 for your location concerning output power. You will need a computer and the Ethernet cable to connect to the local maintenance terminal (LMT) on the Nova-243 unit. Through the LMT you can access the eNB GUI to enter basic configuration parameters so the eNB can connect to the network and to the Baicells CloudCore.

The 10W eNB has a sleek form factor -- 17.3” (H) x 9.5” (W) x 5.5” (D) / 440mm (H) x 240mm (W) x 140mm (D) -- and it weighs 26 lbs (12 kg). When power is applied to the unit, the LED status indicators should illuminate as shown in Figure 2-1 and are described in Table 2-2. Figure 2-1: LEDs Table 2-2: LEDs LED Color Status Description ACT Green Steady On Active cell site, normal transmissions OFF Inactive cell site; the transmitting channel is not working RUN Green Fast flash: 0.125s on, 0.125s off The eNB is booting up Slow flash: 1s on,1s off The eNB is booted and operational OFF No power input, or board failure ALM Red Steady On Hardware alarm, e.g., VSWR alarm OFF No alarms VSWR Red OFF The standing wave is normal.

Refer to the technical specifications in Appendix A. 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). Avoid areas that are prone to impounded water, soaking, leakage, or condensation.

You must protect the Nova-243 eNB, GPS, external antenna, and RJ-45 port against lightning. The eNB has two ground screws which are located on the bottom of the unit. You must connect the ground screws to a reliable outdoor grounding point (earth) using yellow-green ground wire that is at least 16mm2 in diameter. The eNB uses a floating ground on the power line. In principle, always place the grounding as near as possible to the equipment. Ensure that the connection of the grounding points and the ground bar are tight. Rustproof the terminals using rust preventing paint, anti-oxidation coatings, grease, or similar solution. 2.6 Weatherproofing To protect the connection points from weather and climate, clean each connection point before installing cold shrink tubes, per the following (Figure 2–3). 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. Figure 2–3: Weatherproofing

Reference: Baicells Configuration & Network Administration Guide, section 2 The initial basic configuration of the eNB covers the minimal parameters required for the eNB to connect to the backhaul and to the Baicells CloudCore. This section does not cover all configuration options available through the eNB GUI. Please refer to the document referenced above for information on all GUI menus and fields. With the Ethernet cable connected to the eNB ETH port and the other end to a local PC, perform the following steps. 1. Open a Web browser, and enter http://192.168.150.1. The eNB GUI login screen will open (Figure 3-14). Use the default user name and password of admin/admin. Figure 3-14: GUI Login 2. Configure the eNB to connect to the Baicells CloudCore: a. Go to the BTS Settings > Management Server menu (Figure 3-15). b. Enter baiomc.cloudapp.net:48080/smallcell/AcsService as the management server. c. Enter your unique CloudKey that was provided by Baicells. The CloudKey is operator-specific and enables devices, upon power up, to be added automatically to your OMC account. Figure 3-15: Management Server 3. Configure the network interfaces. Go to the Network > WAN/LAN menu (Figure 3-16). a. WAN i. Ensure the Interface name is set to WAN. ii. Enter one or more Domain Name Server (DNS) IP addresses. iii. Set the Connect Type to either Copper or Fiber, per your backhaul network.

as described below. Choose a Connect Via option for this eNB. • Dynamic Host Configuration Protocol (DHCP) – The eNB’s IP address will be obtained dynamically from the local DHCP server. The current DHCP server IP address will be displayed, along with the link speed. When DHCP is selected as the connection method, there are no further WAN fields to configure in this window. • Point-to-Point Protocol Over Ethernet (PPPoE) – not recommended. If PPPoE is selected, you will be prompted to enter the user name and password. The range of each is 1 to 100 digits. You can also enter an access controller name and service name. • Static IP – IPv4 address, netmask, and gateway or IP address of the Domain Name Server (DNS), where multiple addresses are allowed. b. LAN - The LAN address is the same one used to access the eNB GUI: 192.168.150.1. The subnet mask is 255.255.255.0. Figure 3-16: WAN/LAN 4. Optional: If a local DHCP server will be used, go to the Network > DHCP menu and click on the check box next to LAN DHCP Server Enabled (Figure 3-17). Enter the start (lowest) leased IP address and the end (highest) leased IP address in the range. The lease time field is used to indicate how long a leased IP address remains active before it expires. The range of time may be up to 9,999 hours; the default is 12 hrs. Figure 3-17: DHCP

Entity (MME) in the Baicells CloudCore. Go to Network > MME/IPSec Binding (Figure 3-18). Do not change the IPSec Setting fields. They should be left with their default values. In the IPSec Tunnel List, verify there are 2 tunnels enabled. The IPSec Binding should show the 2 CloudCore MME IP addresses, 10.3.0.9 and 10.5.0.9. Figure 3-18: MME&IPSec Binding 6. Configure the eNB's local gateway (LGW) connection to the backhaul network. The eNB splits the data plane and control plane. The data plane is sent out the LGW path, while the control plane is routed through the IPSec tunnel to the CloudCore EPC. a. Go to the Network > LGW menu (Figure 3-19). LGW should be enabled. b. Select one of 3 LGW modes: i. NAT - Network Address Translation modifies the network address in the IP packet headers. To reach a CPE remotely, enter: https://<5+last 4 digits of CPE IMSI> Leave the CPE Web GUI https port as 433; do not change the port number. IP binding uses address range 10.10.0.1 to 10.10.0.254. ii. Router - Enable static IP addressing, and identify the range of addresses. The LGW will assign a local IP address when a CPE attaches. IP binding uses address range 10.10.0.1 to 10.10.0.254. iii. Bridge - Layer 2 will create a virtual interface for each CPE that attaches using a DHCP request to create a 1:1 mapping between the CPE IP address (from the EPC) and the LGW IP addresss. A CPE's MAC address is generated from its IMSI: Convert the last 12 digits to hex, and then prefix it with "8A". For example, if the IMSI = 311980000002918, the MAC would be 8A:E4:2C:8D:53:66.

7. Verify or configure the Quick Settings (Figure 3-20). These settings are important for LTE transmissions. Go to the BTS Info > Quick Setting menu. Some settings will be auto- configured based on eNB model and will be greyed out. Most of the fields are standard LTE types of settings. Figure 3-20: Quick Setting a. When connecting the eNB to the Baicells CloudCore, you must use PLMN ID = 314030 and MME IP addresses 10.3.0.9 and 10.5.0.9. b. Bandwidth setting may be 5, 10, 15, or 20 MHz. c. Select the correct frequency within the band for this eNB to use. d. Select the SubFrame Assignment (SFA or SA). SFA determines the amount of transmission resources in the downlink and the uplink, and is expressed as a ratio of DL:UL. For example, setting the SFA value to 1 means a 2:2 ratio will be applied to transmissions, where an equal number of RF resources will be available in the downlink and in the uplink. i. 0 = 1:3 ii. 1 = 2:2 iii. 2 = 3:1

setting determines the length of the guard period for switching between downlink and uplink transmissions. An SSF = 5 provides a longer guard time and is typically used for cells covering more distance. The farther the distance the UE is from the eNB the more likely it is you will need to use a longer guard period of SSF = 5. f. Enter a unique Physical Cell Identifier (PCI) for this eNB, between 0 - 503. g. Make sure the Cloud EPC field is enabled in order to connect to the Baicells CloudCore. h. Enter a Cell ID for a cluster of eNBs on the same tower or other structure. The Cell ID field is equivalent to the LTE E-UTRAN Cell Identity (ECI). i. As mentioned in step 5 above, to use the Baicells CloudCore make sure the PLMN = 314030 and the MME IP addresses = 10.3.0.9 and 10.5.0.9. j. The Tracking Area Code (TAC) field is used to identify a cluster of cell sites. Enter a value between 0 - 65535 for each unique TAC ID in your network. k. The RF Status field is used to enable or disable RF transmissions. In closed environments, such as when "bench testing" the eNB, always disable the RF for personal safety. l. The Power Modify field allows you to set the output power on each antenna port. This parameter is typically left with the default values, though you may lower it when testing the eNB on the ground. Every 3 dB doubles the power. The eNB output power must stay within regulatory guidelines. NOTE: Any changes to Quick Settings requires a reboot of the eNB. 8. Reboot the eNB for the settings to take effect. The Reboot function is the last menu in the GUI. 3.7 Check eNB Status in Software Once the eNB is powered up, check that the eNB cell status is reported as active in software using either the eNB GUI or the OMC. Each method is described below. 3.7.1 eNB GUI Go to BTS Info > Basic Info and check the Cell Status field, as shown in Figure 3–21. If the status is not reported as active, contact Baicells support.

3.7.2 OMC To check the eNB's status using the OMC, follow the steps below. 1. Open a Web browser, and enter the CloudCore address: https://cloudcore.cloudapp.net/cloudcore/ 2. Go to eNB > Monitor, and check the Active Status column as shown in Figure 3–22. If the status is not reported as active, contact Baicells support. Figure 3–22: Active Status (OMC)

Installing the eNB should be performed only by qualified installation technicians per the operator’s network design plan and according to industry standard safety precautions. Hoisting the RF antenna and eNB onto a tower or other structure may require 2 to 4 people. 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 for pole installations and positioning the equipment on a tower, roof, or other outdoor structure, as well as outside wall installations. NOTE: It does not matter if the eNB or the antenna is installed first, or together at the same time. 3.8.1 Attach eNB to Support Pole (if Needed) 1. After the mounting bracket has been installed on the eNB, install the other mounting bracket on the pole as shown in Figure 3-23. Figure 3-23: Install Mounting Bracket on Pole 2. Insert the eNB vertically into the mounting bracket on the pole, and fasten using M6 fixed screws. The completed eNB attachment to the pole is illustrated in Figure 3-24. Figure 3-24: Completed Pole Mount 3. After mounting the eNB on the pole, go to section 3.8.3.

1. Put the eNB against the wall where you want it to be installed, and mark the 3 drilling hole locations, as shown in Figure 3-25. Figure 3-25: Wall Mount 2. Drill three ½-inch/12-mm diameter sized holes on the wall where marked. Fix the eNB unit on the wall using the M10*80 expansion screws. 3. Continue on to section 3.8.3. 3.8.3 Recommendations for Installing In general, it is best to 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 from the antenna. This section provides guidance on GPS placement considerations and explains how to install the eNB and an omni or directional antenna on an outdoor tower, building, or other structure. 3.8.3.1 GPS Positioning Considerations Consider the following concerning GPS 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 45 to 90 degrees 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.  The GPS antenna should be installed within 45 degrees to the lightning rod. 3.8.3.2 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.

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 or verify reliable weatherproofing as explained in section 2.6 of this document. 3.8.3.3 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 3-26. • 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 3-26: Assemble Directional Antenna Once the antenna and eNB unit are installed securely in the proper position, verify grounding and lightning protection. Apply or verify reliable weatherproofing as explained in section 2.6 of this document.

When installing a directional antenna on a rooftop, it is easier to install if the antenna and eNB 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. 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 unit are installed securely in the proper position, verify grounding and lightning protection (section 2.5). Apply or verify reliable weatherproofing (section 2.6). 3.9 Recheck eNB Status in Software After the eNB has been installed on the outdoor tower or wall, return to the GUI to ensure the eNB cell status is still reported as active and it is connected to the backhaul network. Refer to section 3.7.
