3.1 – Equipment delivery
When you receive the equipment in its packaging:
– check the condition of the packaging,
– if damaged, make your reservations known to the carrier without delay.
3.1.1 – Labels on the equipment and the packaging
Figures given on the examples below are not contractual.
The RBS labels are affixed to the packaging and to the equipment to indicate its contents.
Figure 83 – Example of a label for the RBS unit
The DBS labels are fixed to the packaging to indicate its contents on leaving the factory.These labels
are not affixed to the equipment because the DBS configuration changes in accordance with the site
modifications.

3.1.1.1 – Content of boxes
3.1.1.2 – Storage
If the installation is not to be carried out immediately, the type of packaging will determine the equipment
storage conditions:
– the cardboard boxes should be warehoused indoors, in a well-ventilated and dry space,
– the wooden or laminated crates may be stored outdoors, provided that they are protected from the
rain and direct sunlight.
3.2 – Installing the equipment
3.2.1 – Information required for installation
Appendix 1 – Installation sheet contains a sheet for you to complete, that compiles all the general
information needed for the installation procedure.
3.2.2 – Precautions
Installation is designed to meet all requirements concerning electromagnetic compatibility and safety.
The performance of the equipment depends on installation practices (cable installation, ground
connections, etc.) which should be based on best trade practices and which may be degraded if theses
pratices are not respected.

3.2.3 – Tools required
The installation team must possess a standard installation toolkit (containing, in particular: drill, drill bits,
soldering iron, cable tie pliers, terminal pliers).
The list of tools required for the mechanical installation of the equipment is given below:
To get the commercial codes of these items, please consult Appendix 5 – Correspondence between
commercial codes and industrial codes relating to the BS which gives the connection between industrial
and commercial codes.
3.3 – Installation of outdoor equipment
Considerations
– Outdoor equipment installation involves:
• installation of the mechanical system (also called "pole mounting" system) which supports the
X-Pol RBS and facilitates antenna alignment,
• installation of the X-Pol RBS assembly and its antenna,
• installation of the connection cable connecting the X-Pol RBS to the DBS rack.
– Outdoor equipment installation should guarantee a precise and fixed antenna pointing.
– The X-Pol RBS location and its antenna orientation should arise from a planning analysis in order
to optimize the sector coverage. These elements must be imperatively known with precision by
the installation staff.
– Antenna orientation is carried out according to geometric criterion (using compass and inclinome-
ter).
Tool Use
No. 6 Allen wrench (for 8 mm screw) Antenna alignment
16/17 mm box wrench and flat wrench Used for pole mounting and for fine adjustment of the
antenna and various tightening operations
16/17 mm Torque wrench Used for pole mounting and various tightening operations
20 mm flat wrench For attaching the "N" coaxial connectors
Compax "Mars Actel OSA3" insertion
and extraction tool Wiring the COMPAX (mars actel cad) terminal strips
Essential compass and inclinometer
(not supplied) Pointing the antenna
5 mm Allen key (for M6 screw) For mounting the antenna
10 mm flat wrench For fixing the ground terminal
8 mm Allen key (for M10 screw) For tightening the different parts of the pole mounting

– All the outdoor equipment assemblies are designed for installation without any particular protec-
tion. However, the following recommendations must be respected:
• make sure that the reception metallic structure has a perfect stability,
• do not install the equipment below bird nesting areas,
• do not attach the equipment to chimneys which give off fat deposits, dust and other aerosols
which are liable to be deposited on the equipment,
• do not install the equipment in proximity to sources of heat,
• do not place the equipment in proximity to corrosive gas outputs,
• do not place the equipment below roof run-offs not equipped with guttering (high risk of micro-
wave short-circuit),
• do not attach the equipment to a structure prone to vibrations,
• do not cross the antenna field.
– Two types of installation are possible:
1. installation on a tube or pole, using threaded U-bolts and nuts.
Note: the tube selected should be sufficiently rigid to resist vibrations that may give rise to antenna
misalignment.
3.3.1 – Spatial separation for Base Station Antennas
In band-plans where the uplink and downlink frequency separation is large, then the distance required
between the Tx antenna and the RX antenna might be negligible. Where the band-plan is contiguous
and uplink and downlink frequency separation is small, or non-existent, the distance required between
the Tx and Rx antennas must be greater. Use this document to plan required between the antennas in
installations where the use of contiguous band-plans and small frequency separations require a
substantial.
It is important to note that this document contains general recommendations. The unique characteristics
of every rooftop may require a customized layout for each installation. For example, where a larger roof
accomodates a larger distance between Tx and Rx antennas, it is possible to minimize frequency
separation. If a small rooftop prohibits a large distance between Tx and Rx antennas, the frequency
separation can be increased to compensate.
These table lists the minimum antenna separation requirements for various relative antenna
configurations. With these separations, no guard band is required between the uplink and downlink
frequencies.
