1. Overview

1.1 Introduction

The Baicells Nova227 Outdoor 2*250mW Time Division Duplexing (TDD) eNodeB (eNB) is an outdoor micro base station that enables wired and wireless broadband access to Long-Term Evolution (LTE) backbone networks (Figure 1-1). The low-cost Nova227 eNB supports high-speed broadband data and voice services, helping telecom operators, broadband operators, and enterprises to serve customers in locations that might otherwise be difficult to reach.

Figure 1-1: Nova227 eNB

The Nova227 includes an integrated Global Positioning System (GPS); optionally, the operator may install external GPS antennas with each eNB. The eNB comes pre-configured so that installation is simplified and connection to the core network may be plug-and-play.

Baicells provides a GUI interface that may be accessed locally or remotely to configure and manage the eNB. Additionally, Baicells offers a Software- as-a-Service (SAAS) solution called CloudCore. CloudCore comprises the LTE Evolved Packet Core (EPC) network functions (Figure 1-2), which are managed by Baicells, and provides operators an account to use the Operations Management Console (OMC) and the Business and Operations Support System (BOSS) applications. OMC is used to manage all network elements across multiple sites in the network. BOSS is used for subscriber management.

NOTE: Local versions of EPC and OMC+BOSS are also available. For information on these options, please contact your Baicells sales representative.

2. Preparing to Install

2.1 Personnel & Network Design

Installation personnel should follow standard, industry safety precautions when installing a Baicells Nova227 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 and materials normally used during an installation, refer to Table 2-1 describing cables that will be needed. These materials can be purchased through a Baicells authorized supplier. Additional information can be found at Baicells > Partners.

Table 2-1: Materials

You will need a computer and the Ethernet cable to connect to the local maintenance terminal (LMT) on the Nova227 unit. Through the LMT you can access the eNB GUI to enter basic configuration parameters and check the eNB status in software.

2.3 Form Factor

The Nova227 eNB has a sleek form factor: 9.8 in (H) x 9.8 in (W) x 3.2 in (D) / 248mm (H) x 248mm (W) x 80mm (D). It weighs only 4.4 lbs (2 kg). Figure 2-1 shows the side LED indicators and interface. The LEDs are explained in Table 2-2, and the interfaces in Table 2-3.

PoE+ power supply

2.4 Location & Environment

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). Avoid areas that are prone to impounded water, soaking, leakage, or condensation.

2.5 Grounding & Lightning Protection

You must protect the eNB, antenna, and GPS against lightning. All Nova eNBs use a floating ground on the power line. Following are guidelines concerning grounding.

• The yellow-green ground wire must be at least 16mm² in diameter.
• In principle, always place the grounding as near as possible to the equipment.
• Connect to a reliable outdoor grounding point (earth) using one ground screw.
• The connection of the grounding points and ground bar need to be tight and reliable.
  Rustproofing the terminals, e.g., with anti-oxidant coating or grease, is required.

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 2-2).

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 3-8: Check LEDs

After checking to see that all connections are secure and the eNB hardware is operating as intended, continue to section 3.6. If the eNB is not operating properly and you have double-checked that all steps up to this point were completed correctly, please contact Baicells support before continuing.

3.5 Enter Basic Configuration

Reference: eNodeB Configuration Guide

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 3-9). Use the default user name and password of admin/admin. Later, you will be able to enter a more secure password.

Figure 3-9: GUI Login

2. Configure the eNB to connect to the Baicells CloudCore:

a. Go to the BTS Settings > Management Server menu (Figure 3-10).
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 operatorspecific and enables devices, upon power up, to be added automatically to your OMC account.

Figure 3-10: Management Server

3. Configure the network interfaces. Go to the Network > WAN/LAN menu (Figure 3-11).

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.
iv. The eNB can use one of 3 connection services: DHCP, PPPoE, or IPV4 Static IP, 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. When the Connect Via option “DHCP” is selected, the current DHCP server IP address displays, along with Subnet Mask, Gateway, and DNS Servers information. 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.
• IPV4 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 3-11: WAN/LAN/VLAN

4. Verify the core network connection between the eNB and the Mobility Management Entity (MME) in the Baicells CloudCore. Go to Network > MME/IPSec Binding (Figure 3-12). Do not change the IPSec Setting fields. They should be left with their default values. In the IPSec Tunnel List, verify there are two tunnels enabled. The IPSec Binding should show the two CloudCore MME IP addresses, 10.3.0.9 and 10.5.0.9.

Figure 3-12: MME &IPSec Binding

5. 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 3-13). LGW should be enabled.
b. Select one of three LGW modes:

• NAT – Network Address Translation modifies the network address in the IP packet headers. To reach a CPE remotely, enter: https://<eNB IP address><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.
• 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.
• 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 address. 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 = 117040000002918, the MAC would be 8A:95:02:F9:B6:6.

Figure 3-13: LGW

6. Check or configure the Quick Settings (Figure 3-14). 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 3-14: 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 range 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.

• 0 = 1:3
• 1 = 2:2
• 2 = 3:1

e. Select the Special SubFrame Pattern (SSF or SFP) value, either 5 or 7 (default). This 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.

NOTE: This field will not appear in HaloB mode.

j. S1 Connection Mode is set to One or All. This is the connection mode of the S1 interface between the eNB and the core network.

NOTE: This field will not appear in HaloB mode.

k. 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.
l. 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.
m. 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.

7. Reboot the eNB for the settings to take effect. The Reboot function is the last menu in the GUI.

3.6 Check eNB Status in Software

After the eNB is booted up, check that the eNB cell status is reported as active in software using the eNB GUI or your OMC account. Each method is described below.

3.6.1 eNB GUI

Go to the BTS Info > Basic Info window and check the Cell Status column, as shown in Figure 3-16. If the status is not reported as active, contact Baicells support.

Figure 3-15: Active Status (eNB GUI)

3.6.2 OMC

To check the eNB’s status using 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 field as shown in Figure 3-16. If the status is not reported as active, contact Baicells support.
