Baicells Nova846 Outdoor 8x5W eNodeB User Guide

Product Overview

Introduction

The Baicells Nova846 is an advanced dual-mode outdoor integrated eNodeB (eNB) product that operates in LTE Time Division Duplexing (TDD) mode. This 8x5W eNB is capable of operating in Carrier Aggregation (CA) mode or Dual Carrier (DC) / split mode. Combining a variety of technologies, the Nova846 provides wireless coverage solutions, which will offer users with high-speed broadband wireless Internet access. It also can help operators improve outdoor coverage, enhance network capacity, eliminate blind spots and improve cell edge rates.

In CA mode, contiguous or non-contiguous channels are aggregated to provide up to 40 MHz bandwidth. This essentially doubles the downlink capacity when the CA mode is used with all CAT6/7/15 user equipment. In DC mode, each carrier is treated as an independent cell, supporting 128+128 users, and each supporting 20 MHz bandwidth. Using a Nova846 in DC mode simplifies and streamlines the deployment of split sectors.

In addition to having the option to operate Nova846 in either CA or DC mode, HaloB (an embedded MME option) comes as a default feature in the base software. Baicells’s patented HaloB solution migrates the necessary core network functions to the eNB.

The Nova846 can be widely used by telecom operators, broadband operators, and enterprises, etc.

Installation Tool

NOTE: Other accessories have been packed in the packing box.

Install GPS Antenna

Read the following GPS antenna installation requirements before installing it on the eNB.

• No major blocking from buildings in the vicinity. Make sure the space atop is at least 45 degrees unblocked by any buildings.
• Avoid installing the GPS antenna in the vicinity of any other transmitting and receiving devices, to avoid interference.
• The GPS antenna should be installed within 45 degrees to the lightning rod.

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 2-1).

**Figure 2-1 GPS Antenna Installation

**

NOTE: The eNB may adopt different models of GPS antenna, so the GPS antenna may not the same as above figure. But the installation steps that fix it on the eNB is the same.

Weatherproofing

To protect the connection points from weather and climate, clean each connection point before installing cold shrink tubes, per the following figure.

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.

Install on Pole

Check to ensure the diameter of the pole is in the range of 1.6 inches to 3.9 inches (40mm to 100 mm). The position of the RRU on the pole should be at least 47 inches (120 cm) in height.

The brackets have been pre-assembled in manufacturing before packing. It includes two parts, one is pre-assembled on the back of the device. The other one is for pole mounting or wall mounting, as shown in Figure 2-2.

Figure 2-2 Pre-assembled Device

Following steps introduce how to fix the pre-assembled eNB on a pole.

1. Take apart two clamps from the assembled bracket.
   

2. Put the bracket against the pole and assemble two clamps back. Note that the sequence of flat washers, spring washers and nuts keeps the same with original.
   

3. Fasten the pole bracket to ensure the bracket is firmly fixed on the pole.
   

4. Hang the device (with bracket) on the pole bracket. Ensure bracket is firmly fixed on the pole. the screw on the bottom of the bracket clip into the groove on the pole bracket, and then fasten the screw.
   

Install on Wall

Take apart assembly bracket first, only remains the wall bracket, as shown in Figure 2-3.

Figure 2-3 Wall Bracket

Following steps introduce how to fix the pre-assembled eNB on a wall.

1. Put the wall bracket against the wall and mark two drilling locations with a marker pen.
   

2. Drill two holes at the marked locations and install expansion bolts.
   

3. Hang the wall bracket on expansion bolts, and fasten with flat washers, spring washers and nuts.
   

4. Refer pole mount step to hang the device on the wall bracket.
   

Connect Cable

NOTE:

1. According to the requirements of the site, both DC and AC power supply are provided to support different requirements of installation site. If DC power is selected, the power cable connects to the DC power supply directly. If AC power is selected, the power cable must connect to the AC power supply through a DC-AC adaptor.
2. The antenna ports and CAL/GPS port must have waterproof protection.

Power On

Power on the eNB, and wait a few minutes while the eNB boots up. Per the previous figures, check that the LED indicators are lighting as expected.
