3 INSTALLATION
3.1
WARNINGS AND ALERTS
Radio Frequency Energies
There may be situations, particularly for workplace environments near high-powered RF sources, where
recommended limits for safe exposure of human beings to RF energy could be exceeded. In such cases,
restrictive measures or actions may be necessary to ensure the safe use of RF energy.
High Voltage
The equipment has been designed and constructed to prevent, as far as reasonably, practicable danger.
Any work activity on or near equipment involving installation, operation or maintenance must be, as far as
reasonably, free from danger.
Where there is a risk of damage to electrical systems involving adverse weather, extreme temperatures,
wet, corrosive or dirty conditions, flammable or explosive atmospheres, the system must be suitably
installed to prevent danger.
Protective Earthing
Equipment provided for the purpose of protecting individuals from electrical risk must be suitable for the
purpose and properly maintained and used.
Handling Precautions
This covers a range of activities including lifting, lowering, pushing, pulling, carrying, moving, holding or
restraining an object, animal or person. It also covers activities that require the use of force or effort, such
as pulling a lever, or operating power tools.
Electrostatic Discharge (ESD)
Observe standard precautions for handling ESD-sensitive devices. Assume that all solid-state electronic
devices are ESD-sensitive. Ensure the use of a grounded wrist strap or equivalent while working with
ESD-sensitive devices. Transport, store, and handle ESD-sensitive devices in static-safe environments.

3.2
SITE PLANNING CONSIDERATIONS
Site Considerations
The site considerations are listed below:
•
•
•
The distance between the donor antenna and the BS should satisfy line of sight requirements for
maximum coverage area. The received spots accept field intensity at least -70dBm.
Make sure that TX and RX antennas isolation should more than the max gain that of -15dB.
Supply power near by the BS and easily access to the grounding spot.
Installation Location
Mounting surface shall be capable of supporting the weight of the equipment.
In order to avoid electromagnetic interference, a proper Mounting location must be selected to minimize
interference from electromagnetic sources such as large electrical equipment.
Chassis output interface should install higher 1.2m than the ground.
Environmental
Humidity has an adverse effect on the reliability of the equipment. It is recommended to install the
equipment in locations having stable temperature and unrestricted air-flow which should under the
temperature that of -33oC ~+55oC and relative humidity of maximal 95%.
The installation location for the product should be well ventilated. The equipment has been designed to
operate at the temperature range and humidity level as stated in the product specifications in the
datasheet.
Direct sun light exposure to the equipment should be avoided. Provide additional shelter if necessary.
Powering
The power supply unit (PSU) provides power to all modules within the equipment. Depending on the
product variant, it is recommended that the PSU operates on a dedicated circuit breaker or fused circuit.
Grounding Requirement
Verify that the equipment has been well grounded. This includes antennas and all cables connected to
the system. Ensure lightning protection for the antennas is properly grounded.
Cable Routing
Depending on equipment configuration, a variety of types of cables are required. Where applicable,
ensure cables are properly routed and secured so that they are not damaged.
Cable requirements are as follow:

4 COMMISSIONING
4.1
PRE-COMMISSIONING TASKS
After equipment installation, perform the following steps before equipment powering and commissioning,
check that the expected voltage, current, and power levels do not violate any ratings. Double check all
connections including ground before applying power. Do not manipulate circuits or make changes when
power is applied:
•
•
•
•
•
Visually inspect the power connection within the equipment. Ensure that the power cable is correctly
and securely connected, including grounding wire, RF cable and optical cable.
Check grounding connection and verify that the ground resistance is less than 5Ω.
Connect the equipment to the PC installed with OMT software.
Check antenna system return loss which working frequency band return loss should less than -14dB
(VSWR < 1.5)
The online commissioning can be commenced with following the commissioning steps.

Observation
Activate the OMT Main window. The system Initialization will
completed in about 2 minutes.
Click “Connect” button to enquire the repeater’s status. Proceed if
there is no alarm; else check the failure and attend to the alarm.
Keep RF switch ON and set the channel number of the repeater’s
operating frequency.
Observe DL input power from measured value. Align the direction
of donor antenna until the DL input power reading is maximized.
Note: To ensure that the measured DL input power is accurate, one
should set the DL ATT to “0” before performing the check.
Go to [Properties Info] and set [Equipment ID].
Enable the power supply by selecting “On” in [RF] -> [Switch]; go to
[Properties Info.] -> [Comm. Config.] and set OMC Phones No. , the
service No. of SMSC, Report Mode.
Select the equipment controlled and monitored parameters.
If the external devices are connected to the equipment for
management, please enable in the [External Alarm Info.] Interface.
Use test-handset to verify field intensity within the coverage area. If
needed, realign the service antenna to achieve the desired
coverage.
Note: If during operation, the equipment gain could not be set to
maximum or the output power is not high enough due to insufficient
donor and service antennas isolation, then the antennas’ position
should be changed to increase isolation. If the output power is too
high and ALC is activated, then adjust the DL ATT to achieve
optimal DL Gain.
Adjust UL gain and perform test calls. Typically, the UL gain is set
around 5dB less than DL gain. Perform test calls in the coverage
area while adjusting UL gain if required.
Note: If the repeater is near the BTS and the test call performance
is poor, this may be due to UL noise interference to the BTS. Users
can calculate and determine if the repeater UL noise will interfere
with the BTS.
Verify again that there is no unacceptable interference to BTS.

5 MAINTENANCE
The RX-8139 repeater is designed for trouble-free operation and generally does not need maintenance.
Maintenance activities should only be carried out by trained personnel.
The equipment operation status can be observed remotely through OMC.
Periodic inspection of the repeater equipment(s) is recommended, the recommended tasks includes:
Inspect and record operation status and output power of the repeater from OMC or OMT.
Verify the direction and position of antennas. Re-align if necessary.
Make sure the cable gland and sealing on the RF cable connectors are not damaged.
Verify lightning and grounding protection is in good condition.
