1. Product Overview
Introduction
The Baicells Nova442i is an advanced two-carrier outdoor eNodeB (eNB) compliant with
3GPP LTE TDD technology. This 4x4W eNB operates in Carrier Aggregation (CA) mode
or Dual Carrier (DC) mode.
In CA mode, Nova442i supports 2CC (2 component carriers) DL/UL CA. 2CC DL/UL CA
doubles DL/UL peak throughput comparing to that of a single carrier. By aggregating 2
separated spectrum resources into a virtual contiguous spectrum resource. In DC mode,
each carrier is treated as an independent cell, supporting 96+96 users, with each cell
supporting 5, 10, 15, or 20MHz bandwidth. Using a Nova442i in DC mode simplifies and
streamlines the deployment of split sectors.
In addition, HaloB (an embedded EPC option) is available on the Nova442i as part of the
base software. The Baicells patented HaloB solution migrates the necessary core
network functions to the eNB.
Highlights
Following are some of the key Nova442i highlights.
ú Standard LTE TDD Band 40/48
ú GUI-based local and remote Web management
ú Excellent Non-Line-of-Sight (NLOS) coverage
ú Peak rate: Up to DL 290Mbps and UL 70Mbps with 2x20MHz bandwidth

Installation Environmental Requirements
In addition to network planning, 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 prone to impounded water, soaking,
leakage, or condensation.

Lightening & Grounding Protection
You must protect the eNB, antenna, and GPS against lightning. Following are guidelines
concerning grounding.
" The yellow-green ground wire must be at least 10mm2 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.

3. Installation
Unpacking
Before opening the box, make sure the package is in good condition, undamaged and
not wet. During the unpacking, avoid potential damaging impacts from hits or excessive
force.
Once unpacked, check whether the quantity is consistent with the packing list.
Installation Procedure
Figure 3-1 provides an overview of the installation process.
Figure 3-1 Installation Process
Install on Pole
The eNB mounting bracket is assembled in manufacturing before packing. The only
action required by the installer is to fix the assembly on the pole.
Check to ensure the diameter of the pole is in the range of 2.4 inches to 3.9 inches
(60mm to 100 mm). The position of the gNB on the pole should be at least 47 inches
(120 cm) in height.
Follow the steps below to install the eNB on a pole.
1. Assemble the mounting bracket.
a) Insert four M10 bolts on the mounting bracket, and fasten with flat washers,

12
spring washers and hex nuts.
b) Assemble two clamps on M10 bolts, and fasten with flat washers, spring
washers and hex nuts. The reserved distance to the mounting bracket is
approximately the diameter of the pole. Hex nuts do not need to be fasten.
c) The mounting bracket assembling is complete.

13
2. Put the assembled mounting bracket from the top of the pole. Adjust the position of
clamps and fasten hex nuts.
3. Put the eNB from up to down to the bottom, fasten with the M6 captive screws on
both sides of the bracket. At last, install the lightning rod.
Two installation directions are supported.

Connect Cable
3.4.1 Cable Laying Requirements
General requirements:
" Bending radius of Ethernet cable and grounding cable: > tripled of the diameter of
the cable.
" Bind the cables according the type of the cable, intertwining and crossing are
forbidden.
" An identification label should be attached after the cable is laid.
Grounding laying requirements:
" The grounding cable must connect to the grounding point.
" The grounding cable must be separate with the signal cables, of enough distance to
avoid signal interference.
3.4.2 Connect Ethernet Cable
The Ethernet cable must be not less than 7mm. The CAT6e shield Ethernet cable is
recommended.
ATTENTION: If the diameter of the Ethernet cable is less than 7mm, the connector
cannot be locked. The eNB will be flooded and damaged.
The connector is a PG connector, it is self-waterproofed.
1. Unscrew the PG connector in sequence.
2. Pass through the Ethernet cable the unscrewed connector based on original
sequence.
3. Insert the RJ-45 connector to the ETH/POE port at the right bottom of the eNB.
