1. Introduction

Flexi Multiradio BTS GSM/EDGE is a Multiradio/Multicarrier BTS that can operate in GSM,

WCDMA or LTE in dedicated or concurrent mode. This BTS utilizes modular Flexi BTS platform

design principles common with Flexi Multiradio BTS GSM/EDGE and Flexi WCDMA BTSs. The

BTS uses a Multicarrier Power Amplifier and delivers high power efficiency for medium to large

GSM configurations. The BTS uses a common RF module for different technologies in the same

band and hence does not require external Multiradio Combiners. This further enhances the power

efficiency on a GSM/WCDMA or GSM/LTE Multiradio site.

Here, this document will highlight the installation of LTE Flexi Multiradio BTS based on Customer

requirements.

Title


Installation principle with DC power supply

The installation of the optical cable between the System Module and RF Module requires two small

form-factor pluggable (SFP) optical transceiver units that are plugged into both the System Module

and RF Module. Optical cables are used for creating an optical interface between the System

Module and RF Module.

Note 1: Incorrect cables and seals may not provide secured weather protection. In Outdoor

installations, use only tested IP65 class outdoor cables with seals provided by Nokia

Siemens Networks.

Note 2: Over bending the optical fibre cables damages the cables and can detach or damage

The connectors. Do not bend optical fibre cables to a radius smaller than the

minimum radius of 70mm (2.8 in).

10. Antenna Line Design: The jumper cable is a flexible low loss cable (1/2"), which is used at the Antenna & RF Module

ports. 7/16 connector are made of silver plated brass or a special grade of copper. All connectors

are IP68-classified. Cable clamps are easy and quick to install.Design of the clamps prevents over

tightening of a jumper cable.

10.1. Antenna Type used for Mobily LTE Project: The type of antenna being used for this project is as follows

1. K742236V01 commonly used

10.2. Antenna Line Installation Practices 10.2.1. Rules for Safe & Healthy Working Environment:

Use adequate personal protective belts (approved lines, anchor points, harnesses, etc.).

Erect proper retaining barriers around the edge of the roof.

Always consider your safety and the safety of others.

Use tools and resources to make physically demanding work easier.

Make sure you have robust (temporary) ladders and safe access routes. 10.3. Antenna jumper termination and weatherproofing:

The external antenna jumper cable should be terminated and complete Weather proofing should

be applied. Below are the steps:

Needed Materials for taping:

1 Insulation tape

2 Self amalgamating tape

3 Cable tie

Connect jumper connector to antenna port following the required torque value 25Nm.

Apply self-amalgamating tape for two rounds, start on top and will end on top as well.

Start insulation round from down and apply three round of tape, so taping will end

to the top. Observe 50mm distance from the jumper connector to the edge of the tape.

Finally secure tape ending with cable tie to prevent tape loosening and applying better

waterproofing to jumper connector and antenna connection point.

10.4. Antenna mounting:

Antennae can be installed on the green field tower, on the rooftop and monopole sites.

It is better to install the antenna first to its planned position.

All the Antenna line information is provided in RF Data sheet. The installation of antenna is

to be done according to the data mentioned in RF Data sheet.

Title


Procedure:

Mount the antenna on its plan position, check that there is no obstruction and consider

a possible optimization i.e. antenna can be able to move for tilting or panning.

Correct azimuth of the antennas direction must be followed using recommended

compass.

Electrical tilt can be done by adjusting the e-tilt adjustment screw at the bottom of the

antenna.

The horizontal separation b/w 3G antenna & Existing antenna must be 600mm.

The vertical separation b/w 3G antenna & Existing antenna must be 300mm.

Rooftop Site:

For roof type site, install antenna to its planned position. Do the directing and tilting according to

Radio N/w Planning (RF Datasheet).

Monopole Site: Follow above steps for antenna installation and orientation.

10.5. Jumper Cable Installation:

Check possible damage on the cable before installing it. Survey the cable run for any obstruction

and report to supervisor if any.

10.5.1. Antenna jumper routing:

Jumper cable should be routed to the tower, braces and mounting pole using specified

clamp so that no jumper is hanging on tower.

Antenna jumper cable connecting to RF Module can be routed using supplied clamps.

Distance of clamp support for jumper cable is 1m so for 3m jumper we need 3 support

clamps and that for 6m we need 6 supports. Feeder cable Specification: , 7/8 and 1-5/8 feeder cables are used in general depending on

the height of the tower.

Feeder

Type

Length

1/2" 0-20m

7/8" 0-44m

1 5/8" above 44m 10.6. Bending radius must be followed as per specifications: Each feeder/jumper type has corresponding minimum bending radius to be followed to avoid

damage to the feeder/jumper that will cause high VSWR result in the antenna line.

10.7. Antenna measurement (Antenna Sweep Test): To make sure that installation has been carried out correctly, antenna sweep test needs to be done.

The agreed value is 1.4 for VSWR, -14dB for Return loss and 1.05 for DTF.

***The measurement (sweep test) is carried out through jumper connected to BTS up to

the Antenna port. Here, in this case measure the sweep test for the jumpers provided before

installing them, so that there will not be any issue during integration.
