1 Overview
1.1 Introduction
The Baicells Nova-227 Outdoor 2*250mW Time Division Duplexing (TDD) Base Station is a
high-performing outdoor micro base station that enables wired and wireless broadband
access to 3G TDD Long-Term Evolution (LTE) backbone networks. The Nova base station makes
use of the current LTE transmission resources to reduce the operator’s investment in providing
low-cost, enhanced coverage. Each base station 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.
The base station is a component of the operator’s cell site and includes an integrated Global
Positioning System (GPS). The operator selects and provides one omni or directional Radio
Frequency (RF) antenna to install with each base station. Optionally, the operator may install
external GPS antennas with each base station.
Each base station 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 base stations
and Customer Premise Equipment (CPE).
Additionally, Baicells offers a Software-as-a-Service (SAAS) solution called CloudCore.
CloudCore, also referred to as BaiCloud, includes an Operations Management Console (OMC)
for managing multiple sites across the network and a Business and Operations Support System
(BOSS) for subscriber management. Soon, CloudCore will include an Evolved Packet Core (EPC)
module for high-speed packet processing and high-quality mobile broadband services. The
EPC module is currently under field testing.
Figure 1-1 illustrates the system architecture of the Baicells broadband wireless access
solution. In the photo, the base station shown is a Nova 1W Generation 1 base station.

•Flexible 2:2 and 1:3 UL to DL transmission ratio
•10 MHz and 20 MHz operation bandwidth
•Internal antenna and GPS
•PoE+ power supply, requiring only one Ethernet cable for power and data transmission
•Security services to protect against risk and illegal intrusion

3 Installation Preparation
3.1 Personnel
Installing the base station on a tower, building, or other structure may require at least two
people or a tower crew. Installation personnel should follow standard safety precautions
concerning height, electricity, and other regulations. Baicells recommends that installation
personnel review this entire installation guide prior to beginning the installation.
3.2 Operator Network Design Plan
Installers should refer to the operator’s network design plan for information about specific
network components, IP addressing, radio frequency (RF) coverage goals for the specific cell
site, and initial configuration settings.
Each cell site may be unique in terms of the type and number of components to install, the
coverage area, the user requirements, and so forth. Clearly identify the structure on which the
base station equipment will be installed, the intended height where the antenna and base
station will be attached, the degree of antenna down tilt, and other necessary specifications
that may impact the success of the installation.
3.3 Materials and Tools
Tables 3-1 and 3-2 describe the materials and tools required during the installation. Materials
may be purchased through Baicells or through an authorized supplier:
https://na.Baicells.com/where-to-buy/. Match the frequency range of the antenna with the
base station. Consult regulatory rules concerning output power specific to your location.

3.4 Software
As part of finishing the base station installation process, you will need a computer to log in
and verify that the base station status is reported as active by:
•Using a local Ethernet connection to the base station or a Web browser to access the
base station GUI client application; or
•Accessing the internet to reach the cloud-based OMC application.
3.5 Form Factor
The Nova-227 base station 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 3-1 shows the side LED indicators and interface. The LEDs are explained in Table 3-3,
and the interface is described in Table 3-4.

3.6 Location and Environment
When determining where to place the base station, 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.
Avoid locating the base station 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.

4 Installation
Some cell site structures may have existing frameworks for attaching the base station and
antenna. For purposes of explaining the installation procedure, this section assumes the base
station will be installed on a support pole or on a wall.
4.1 Process Overview
Figure 4-1 provides an overview of the installation process.
Figure 4-1: Installation Process Overview
4.2 Install Base Station on Pole or Wall
4.2.1 Install on Pole
Check to ensure the diameter of the pole is in the range of 1.6-3.9 inches (40-100 mm). Follow
the steps below to install the base station on a pole.
1. Assemble the mounting bracket, and attach and fasten the screws (Figure 4-2).
Figure 4-2: Mounting Bracket

15
2. Attach the base station to the pole, passing the omega through the threaded rods and
then loosely fastening the two nuts (Figure 4-3).
Figure 4-3: Pole Attachment
3. Adjust the base station to the proper angle based on RF coverage goals for the site,
and tighten the screws.
4.2.2 Install on Wall
Ensure that the wall can bear at least 4 times the weight of the base station. Follow the steps
below to install the base station on the wall.
1. Fit the base station on the wall, and mark the drilling locations (Figure 4-4).
Figure 4-4: Mark Drilling Locations
2. Drill four .5 in/12mm diameter and 3.2 in/80mm deep holes in the wall at the marked
locations.
3. Check the up/down direction of the installation rack, and then fix the base station to
the wall using M8*80 expansion screws. (The U-shape clamp is not used for wall
installations.)
4. Fix the base station on the bracket, and adjust it to the proper angle based on RF
coverage goals for the site.

16
4.3 Connect Ethernet Cable
Follow these steps to attach the Ethernet cable to the base station.
1. Unscrew 3 screws on the cover of the wiring cavity (Figure 4-5) using M4 cross
screwdriver, and open the wiring cavity co ver.
Figure 4-5: Wiring Cavity
2. Connect the Ethernet cable to the ETH interface in the wiring cavity.
3. Lay Ethernet cable along the wire groove, stretching it outside the wiring cavity.
4. The other end of the Ethernet cable connects to the PoE power adaptor.
4.4 Connect Ground Cable
Prepare the grounding cable according to the actual requirements of the specific site. Refer to
specifications given in section 3.3 Materials and Tools. The grounding screw is located on the
bottom of the base station, as shown in Figure 4-6. Unscrew the grounding screw, connect one
end of the grounding cable to the grounding screw, and fasten it again. The other end of the
ground cable needs to connect to a good grounding point.
Figure 4-5: Grounding Screw

17
4.5 Power on to Check LEDs
Power on the base station and check that the LED indicators are lighting as expected, per
Figure 4-6. Refer to the LED descriptions in Table 3-3.
Figure 4-6: LEDs
4.6 Check Base Station Status in Software
