1 Overview
1.1 Introduction
The Baicells Nova846 (Figure 1-1) is an advanced two-carrier outdoor eNB that is compliant with
Third-Generation Partnership Project (3GPP) on LTE Time Division Duplex (TDD) technology. This
8x5W eNB can operate in Carrier Aggregation (CA) mode or Dual Carrier (DC)/split mode. The
Nova846 supports broadband data access, providing various data service transformation and
transmission capabilities to enable outdoor wireless coverage. This eNB can be used by operators
to improve capacity and throughput while eliminating existing dead zones.
Figure 1-1: Nova846 eNB
As a two-carrier eNB, the Nova846 hardware unit contains two separate eNBs inside one shell.
Having two carriers provides versatile options in how you operate the eNB. The available operating
modes are described in the next section, Features.
The Nova846's primary cell (Pcell) is referred to as Cell 1. The secondary cell (Scell) is referred to as
Cell 2. Each eNB comes pre-configured to simplify the installation. 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 centralized Software-as-a-Service (SaaS) solution called CloudCore.
CloudCore includes all of the essential LTE Evolved Packet Core (EPC) network functions, an
Operations Management Console (OMC) for managing multiple sites across the network, and a
Business and Operation Support System (BOSS) for subscriber management.
In this document, you will find a general description, guidelines, and procedures for installing,
entering basic configuration information, and verifying the operational status of the Nova846 eNB.

1.2 Features
The two-carrier Nova846 eNB can operate in one of several modes:
•Single Carrier (SC)
•CA mode (based on software license)
•DC/split mode (based on software license)
•HaloB mode (embedded in the base software)
•Citizens Broadband Radio System (CBRS) Spectrum Access System (SAS)
SC describes a scenario where the operator wishes to use only one of the two available cells in the
eNB. This may be necessary for operators who have limited licensed spectrum or who are planning
to use the second carrier later as their network grows. In SC mode, only the primary cell (Pcell),
aka Cell 1, is used.
CA provides the ability to aggregate channels from across the full CBRS range, even channels that
are not adjacent. Using CA essentially doubles the downlink capacity when all users have CAT6/7
or later CPEs.
DC (split sector) mode enables the operator to run the Nova846 as two independent carriers for
split sector coverage.
HaloB allows the eNB to function with embedded Mobility Management Entity (MME) capabilities
on board so that the eNB operates independently from the usual cloud connection. HaloB is
standard in the Nova846 eNB as part of the basic software to provide “lite EPC” capabilities. This
enables the user to migrate core network functions to the eNB.
CBRS SAS is a multi-vendor SAS database where CBRS spectrum use is managed dynamically across
operators. The CBRS band covers 3.55–3.70 GHz. Operators must sign up with a SAS provider, which
handles the dynamic frequency assignment and release process. Baicells provides FCC Part 96
certified eNBs, including the Nova846, and CPEs that operate within the Part 96 rules for CBRS. The
Baicells eNBs and CPEs use a Domain Proxy (DP) to connect to the SAS server by leveraging the
existing connection with the OMC.
NOTE 1: Legacy Gen 1 CPEs do not support SAS.
NOTE 2: This installation guide only covers the basic configuration of a single cell for
verifying that the eNB unit is operational during the process of installation. More
detailed configuration guides are available on the Baicells website:

2.3 Grounding and Lightning Protection
You must protect the eNB, antenna, and GPS against lightning. All Nova eNBs have a floating ground
on the power system. Following are guidelines concerning grounding.
The yellow-green ground wire must be at least 5 AWG (16 mm2) diameter.
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 needs to be tight and reliable.
Rustproofing the terminals, e.g., with antioxidant coating or grease, is required.
2.4 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.

No major blocking from buildings in the vicinity. Make sure the space atop is at least
45 degrees unblocked by any buildings.
The GPS antenna should be installed within 45 degrees to the lightning rod.
Do not install the GPS antenna near other transmitting and receiving equipment, to avoid
interference. Do not install it under a microwave antenna or high voltage cable. Avoid the
direction of radiation from other transmitting antennas to the GPS antenna.
The top of the GPS antenna should not be placed in the frontal position of the eNB’s
directional antenna if possible. If an obstruction occurs, it is recommended to install the GPS
antenna in an open and lightning-protected location rather than to the eNB.
When two or more GPS antennas are installed, it is recommended to keep the spacing of more
than 6.74 feet (2 meters) and install multiple GPS antennas in different locations to prevent
simultaneous interference.
GPS antenna feeders cannot be grounded together with ground conductors of interfering
equipment such as air conditioners, motors, and pump motors, etc. to prevent external
interference from being introduced into the antenna system.
Figure 3-2: GPS Installation Requirements
The GPS antenna system is assembled in manufacturing before packing. The only installation step
is to fix the GPS mounting bracket on the eNB with the M4*14 screws (Figure 3-3).
