1 Overview
1.1 Introduction
The Baicells Nova-227 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 Nova-227 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: Nova-227 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) software
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 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 Nova-227 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. The cables are available through Baicells suppliers.

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. Refer to the technical specifications in Appendix A.

11
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.

17
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
operator-specific 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 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. 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.

18
Figure 3-11: 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 3-12). 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 3-12: DHCP
5. 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
3-13). 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 3-13: MME&IPSec Binding

19
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 3-14). 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://<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.
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.
Figure 3-14: LGW
7. Check or configure the Quick Settings (Figure 3-15). 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.

20
Figure 3-15: 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.
i. 0 = 1:3
ii. 1 = 2:2
iii. 2 = 3:1
e. Select the Special SubFrame Pattern (SSF) 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.
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.
