Cautions for Installation
Observe the following safety instructions while installing the Outdoor Pico eNB.
Before Installing
•
Post warning signs in areas where high voltage cables are installed.
•
Post ‘off limit’ signs in areas where accidents are most expected.
•
With guardrails or fences, block open areas such as connecting parts, roof, and
scaffold.
When you install this equipment in the field, it should be installed in a Restricted
Access Location.
While Installing
•
The system power must be cut off before installing.
•
Be careful that boards mounted on the system and the cables among the boards
are not damaged or scratched when the system is transported or installed.
Make sure the power switch of power supply is off when installing the system.
Installing the system with power switch on may cause system damage or fatal
human injury when cables are not correctly connected.
Wear protection gloves and goggles to prevent damage from debris while drilling
holes in a wall or ceiling.
Do not wear accessories such as watches and rings in order to prevent electrical
shock.
Cover the unused ports (conduit, cable gland, and so on) with a waterproof cap
(sealing cap) to prevent infiltration of foreign material such as dust, moisture, or
insects.

Do not use a base station antenna within a distance of 100 cm from people; also
do not co-locate nor operate in conjunction with any other antenna or transmitter in
order to protect the general public from exposure to radio frequency
electromagnetic field.
To prevent foreign substances, outdoor air, and moisture from entering the system
input/output port and cable inlet (including cable gland and conduit), finish them
as follows:
- Unused Inlet:
Use the hole finishing materials, including waterproof cap and rubber packing.
- Cable-installed Port and Cable Inlet
After installing the cable, block any space in the inlet with tape, compressed
sponge, rubber packing, and silicon.
You must not work alone in any key process.
The outdoor fastening materials, such as stud bolts, hex nuts, spring washers, and
plain washers, must be made of stainless steel (STS 304). Otherwise, it may cause
corrosion and rust to fixing materials.
After Installing
•
Cover the cable holes drilled on the floor with a solid cover.
•
Remove any debris produced during work and clean up the installation site.
In the system, the laser beam light runs through the optical cable. Handle the
optical cables with care as the laser beam can seriously damage your eyes.
Do not damage installed cables while cleaning the system.
While cleaning the power supply device, take caution that the device does not
come in contact with foreign objects that may cause power failure.

Marking and Drilling
Marking
Before placing the system, mark the position where the system will be installed
using an ink line or a pen. Also mark the positions where anchor bolts will be
fixed.
As a limited range of tuning is allowed for leveling after the system is mounted on
a wall, perform the leveling test (refer to ‘System Leveling’) to check if positions
are marked to be horizontal or vertical before drilling. If the result shows they are
not horizontal or vertical, then modify the marking positions.
Before starting work, check the fixing method for the Outdoor Pico eNB because
the marking and drilling positions and specifications may differ as per the fixing
method.
When position of the system is determined, place the system on the position. Using
a pen, mark the positions where anchor bolts will be fixed in order to reduce
marking error range.

System Leveling
Leveling refers to compensating for the level difference on the floor when
installing devices horizontally or vertically. Leveling can be carried out using a
vinyl hose, a balance weight, or a level.
This section describes using a spirit level, a commonly used method.
Refer to Table 16. Leveling Using a Level and Figure 15. Leveling Using a Level
(Wall Type) and Figure 16. Leveling Using a Level (Pole Type) to use a spirit
level.
Table 16. Leveling Using a Level
Classification
Description
Test Method
The level is measured based on the position of a bubble after attaching the spirit level
to the top and side of the system.
Evaluation Criteria
Good
Poor
If it is level, the bubble of the spirit level is positioned at the center of both lines.
Corrective Measures
for Poor Leveling
Use an aid such as Bakelite or an auxiliary fixture on the backside of the system to
adjust the height.
Adjust the position of fasteners used to fix the system or its leveling status.

To prevent personal injury caused by an electric shock when using an insulation
tester, make sure the polarity is correct when connecting the Earth/Ground COM
(black) and AC.V (red) lead lines. Do not touch the connected probe inspecting
part of the lead line with your hands and avoid body contact.
Probe
(Inspecting part of the lead line)
Because there is very high voltage, observe the following to prevent any system
damage when measuring insulation resistance
- Before measuring insulation resistance, disconnect all cables connected to the
system.
- Do not measure insulation resistance when power is on.
- Do not measure insulation resistance at any position other than the target
insulation resistance measuring points.

When installing a cable that connects between the AC distributor, Ground Bar, and
backhaul device within the system, inspect the cable path, length, and installation
method.
Follow these guidelines while inspecting the cabling path:
•
Select a minimum cable length provided it does not affect the cable installation
and maintenance.
•
Place the cable in a location where it will not be damaged by external factors
(power line, flooding, footpaths, and so on).
•
In areas where the cable may be damaged by external factors, ensure that
measures are taken to prevent damage to the cable (cable tray, ducts, and
flexible pipe).
Cable Cutting
Measure the exact distance and carefully check the route. Cut the cable using a
cutting tool.
Follow these guidelines while cutting the cable:
•
Cut the cable to the length determined in the ‘Cable Path Inspection’ step.
•
Use a cable-cutting tool specific to the cable.
•
Cut the cable at right angles.
•
Be careful to keep the cable away from any moisture, iron, lead, dust, or other
foreign material while cutting.
•
Remove any foreign material attached to the cable using solvent and a brush.
Cable Installation
Cable installation involves running the cable along a path to the system target
connector or to an auxiliary device after path inspection and cable cutting
completion.
Follow these guidelines while installing a cable:
•
Do not damage the cable.
•
If the cable is damaged, cut the damaged section before installation or replace
the cable.
•
Run the cable to avoid any knots. While installing the cable from a horizontal
section to a vertical section, exercise extra care so that the upper and lower
lines of the cable are not reversed.

Grounding
Grounding is required for protecting the electric systems such as power system,
communication system, and control system, from lightning, excessive-current,
high-voltage, and electric noise. Grounding will substantially reduce the possibility
of accidents, especially when used in combination with other safety measures.
The purpose of grounding is as follows:
•
To prevent human life and the system from excessive current, high-voltage,
and lightning
•
To provide a discharge path for surge voltage generated by lightning and
power switch
•
To protect the system from static electricity
•
To eliminate or minimize the high-frequency potential in system housing
•
To stabilize the potential of the circuit against the ground
Connecting cables without the ground cable may cause damage to the equipment
or physical injury to the worker. Always connect the ground cable.
Ground bar for lightning protector/power/communication must be isolated from
each other. These three ground bars can be grounded using the isolation grounding
method, or branched from ground mesh buried in the ground using the common
grounding method.

Checking RF Cable Connection
After connecting the RF cables, perform the continuity test and feeder cable return
loss to check if it is changed. (Follow latest TS-200 Antenna Transmission Line
Acceptance Standards.)
Measure VSWR of antenna and RF cable.
Connection Part of System External
Interface Connector
Antenna
Measure all the section of the cable ~ . The measured VSWR should be the
specification value or less. If the VSWR exceeds the specification value,
disassemble the connector and measure each section separately.
If the VSWR value for the minimum cable bend radius and length of RF cable is
not applied, the system may not work properly because the RF signals cannot
transmit or receive smoothly. Check and apply the VSWR value for minimum
cable bend radius and length of RF cable.
When measuring VSWR, if you open the antenna port when the transmission
output is not completely off, a spike signal may flow into the reception path. This
may cause damage to LNA. Make sure the transmission output is completely off
when measuring VSWR.
If you install the feeder line which is connected to the system, it may damage the
system and the cable connection. Therefore, install the feeder line to the system's
input port before connecting it to the system.
Depending on the supplier or manufacturer of the antenna, the connector type may
be different. Also, the detail specifications of a connector may be different
depending on cable type even for the same connector type.
Check the detail specifications of a connector before preparing parts.
For example, Mini Din Type-Male: for 1/2 in. Feeder line, for 7/8 in. Feeder Line
As different connector types may be used depending on the RF antenna type,
check the antenna connector before connecting the cable.

GPS Antenna
Installation Requirements for the GPS Antenna
The GPS antenna must be installed in a location where it has the maximum
amount of open sky. The ideal position is one where there are no obstacles that
interfere with the antenna within 10 degrees or more of the horizon (the Elevation
Angle). This allows the GPS receiver to select the best combination or distribution
of GPS satellites which gives optimal performance. Refer to Figure 44. Elevation
Mask and Satellites.
Figure 44. Elevation Mask and Satellites
For good signal strength, it is not necessary to place the GPS antenna on a high
pole or building, which is often required for RFs and microwaves. It may be
installed any place where there are no obstacles blocking the GPS antenna from
the sky and where it is protected from the elements such as outside interference is
suitable. In this case, it can even be installed on the ground.
However, the GPS antenna may be preventedfrom malfunctioning by installing it
in a place where it does not receive reflected satellite signals. As multi-path
interference greatly affects the accuracy of the GPS receiver, it is better to
minimize reflected satellite signals entering through the top of the GPS antenna.

Therefore, the GPS antenna installation location must meet the following
conditions.
•
In a location that can avoid an obstacle/building that interferes with reception
of the GPS signal or causes multi-path
•
In a location that can avoid interference of RF signal that is
transmitted/received at another RF antenna (including steel-framed structure
for RF antenna) or microwave signal
•
In as low as possible location that avoids damage from lightning within
coverage area of a lightning rod
Considering the elevation mask, make the GPS antenna take the signals received at
a valid elevation angle only.
If a GPS antenna is influenced by external interference signals or multi-paths at
a certain place, it is best to install the antenna at another location. An anti-jamming
GPS antenna is recommended, if it is not possible to change the location of the
antenna.
GPS Antenna Sharing
A recommendation to ensure the GPS receiver works properly is to install one
GPS antenna per GPS receiver, and use a GPS-specific splitter only if necessary.
Installing the GPS Antenna
The signals from a GPS satellite have a very low level (-130 dBm). As a result, for
the GPS antenna to receive signals, its installation should be in a place where it
can receive them as direct as possible from as many satellites as possible.
Therefore, it is important to ensure that there is maximum open sky (the visual
field angle must be 360 degrees, and there must be 160 degrees or more above the
horizon). Any obstacle within those angles decreases the performance and
functionality of the GPS receiver.
The GPS satellites are distributed so that eight of them can always be tracked from
any one place around the world, as long as there is no obstacle to them in that
particular place.
For the GPS receiver to operate at its best there must be six GPS satellites always
with a healthy status (that is, there is no obstacle directly between it and the GPS
antenna).
If the position hold operation has been completed, the GPS receiver can only
perform its operations stably if at least one satellite can be tracked continually.

The survey of an object’s position using GPS satellites is based on triangulation.
Three satellites are enough to survey the position of an object by triangulation.
However, to calculate the correct time deviation, a total of four satellites are
required.
Usually, the GPS antenna is installed in a high place, such as on a roof. It must be
installed away from protruding objects, such as trees or buildings. In addition, it
must be positioned away from any obstacle which covers part of the sky around
the horizon of the building where it is installed.
If it is impossible to ensure a completely open sky, install the GPS antenna facing
the equator providing a maximum view of the Southern sky in the Northern

Lightening Arrestor
A lightning arrestor is required when there is a danger of lightning striking a cable
or related part. The lightning arrestor must be installed in a place where the
antenna cable or set of combined cables enters a building or station, or a place
inside the building or station in order to protect the people and equipment inside
the building or station.
If struck directly by lightning, the lightning arrestor, antenna, or cable must be
replaced. Furthermore, inspect the lightening arrestor periodically and replace the
antenna and cable periodically if lightning strikes occur frequently at the site.
The lightning arrestor must be well grounded so that it can transmit a large current
quickly.

Interference Signal
The GPS system is designed so that it has a strong immunity to noise and can
endure interference.
The Samsung GPS receiver provides a quality timing clock in most installations.
However, to ensure that the GPS receiver performs locking successfully and
guarantees uninterrupted timing performance, an interference-free environment is
required for frequencies near the GPS L1 frequency (1575.42 ± 1 MHz).
Interference Types
There are two types of interference which affect the GPS L1 frequency.
•
Narrow band (inband) interference: When a frequency deviation (3.5 kHz),
such as an FM wave, inflows around the GPS L1 frequency (1575.42 MHz).
Narrow band interference is monitored by the spectrum analyzer. But because
it has a time lag, a locking failure or a different type of alarm can occur.
•
Wideband interference: When frequency deviation is more than 7 kHz around
the GPS L1 frequency (1575.42 MHz).
Wideband interference includes the interference induced by the harmonics
from a communication service with a different frequency bandwidth, increased
thermal noise from communication services around the L1 band, inflow of
interference due to unauthorized communication, saturation due to oscillation
of an accessory device, and so on.
You cannot monitor these kinds of interference with a device such as a
spectrum analyzer. If the system has a wideband interference problem, you
should consult an expert in this area.
For bandwidths other than the GPS L1 frequency (1575.42 ± 1 MHz), a GPS Band
Pass Filter (BPF) must be included within the GPS antenna to remove the
interference from the GPS bandwidth. No outband interference must affect the
GPS signals.

Avoiding Interference
If more than one antenna for other communications is installed in the surrounding
area, such as an antenna for a base station or satellite communication, the GPS
antenna must be installed in a location where no interference signals flow.
If interference exists within the GPS L1 frequency bandwidths (1575.42 ± 1
MHz), use a band pass filter (BPF) to prevent interference from affecting the GPS
bandwidth.
Furthermore, if the GPS antenna is installed by a transmitter which operates with a
bandwidth similar to the GPS L1 frequency, the possibility of interference
increases (in this case, interference is caused by harmonics). If the GPS antenna
has a problem due to interference, move it to a different location where
interference signals can be avoided or minimized.
Inband noise includes narrow band noise and wide band noise that occur in an
inband width. (L1, 1575.42 ± 1 MHz)
•
Narrow band noise in an inband width: If it is higher than 108 dBm, it can
affect the operation of the GPS receiver.
•
Wideband noise in an inband width: It may not be detected by a measuring
instrument and may impair the sensitivity of the GPS receiver, and thus affect
its operation.
If there is an outband interference problem, reduce the effects of interference on
the GPS receiver by applying one or more L1 GPS BPFs.
The filter should be installed at the following locations:
•
The input connector of the Samsung GPS receiver
•
Behind the antenna or the front end of a line amplifier
These filters are used to reject jamming tones for outband signals. If interferences
occur in the inband signals, they will result in serious consequences.

When installing a feeder line, the radius of curvature of the sections where cables
bend must be at least the minimum required radius of curvature. If the radius of
curvature for the feeder line installation is less than the allowed minimum, it may
affect the performance of the system.
•
Ensure that the feeder cable does not interfere with steel towers, ladders, and
areas used by people.
•
Connect the connector to the antenna in a straight line. After the connection,
do not apply excessive force.
•
Use the vinyl tape for electricity and heat shrink tubing for the external
exposed part of the connector.
•
Wrap the self-bonding rubber tape overlapping (keep a distance as the half size
of rubber tape) the connector connection part. Wrap the vinyl tape for
electricity twice or more and then cover with the jelly-type Heat Shrink tubing.
Connecting the feeder cable connector is a critical process. It must be performed
