2 EQUIPMENT DESCRIPTION
2.1 FUNCTIONAL BLOCK DIAGRAM
Figure 2: PS BDA Functional Block Diagram
In the downlink, the BTS signals are received by donor antenna of the repeater. After the duplexer, the
signals are sent to the LNA module for pre-amplification and digital RF integrated module for digital filtering
and frequency conversion. Then the DL signals will be sent to downlink PA to amplify power and filter via
duplexer. After amplification, the signals are transmitted at the MT port to the service antenna.
In the uplink, the mobile signals are received by the service antenna. After the MT port integrated duplexer,
the signals are sent to the LNA, integrated module for digital filtering, then to PA for power amplification and
to duplexer. After that, the uplink signals are sent to the donor antenna for transmission back to the BTS.

2.3 EQUIPMENT CONSTITUTION
The typical PS BDA unit consists of the following components:
Power Amplifier (PA): It fulfils power amplification in both UL and DL branches.
Main Control Unit (MCU): The MCU is used to monitor and control the operation of the repeater. It also
provides the communication interface for remote control and indication. LED indicators provide the
operation status of the MCU.
Duplexer: The DPX is located towards the MT terminals and permits the uplink and downlink signals to
share a common antenna.
Digital Integrated Module and Power Amplifier: Consists of Power Conversion module, RF module,
digital process module and monitoring module. Power Conversion module converts +28V DC voltage in to
+9VJK and +9VRF. +9VJK, +9VRF are supplied to monitoring unit and RF unit in integrated module
separately. RF module amplifies and converts the RF signal to IF signal. Digital process module converts
the IF signal into baseband signal via AD conversion and extraction, filtering. After that, IF signal will be
amplified and converted to RF signal by RF module for RF filtering and amplification. Monitoring module
monitors and controls the system parameters and is the interface of both remote monitoring and local
commissioning.
Power Supply Unit (PSU): The PSU converts the input voltage into a stable DC to provide power for the
internal functional modules.

3.2 SITE PLANNING CONSIDERATIONS
3.2.1 SITE PLANNING
Site Considerations
Outdoor equipment are designed to be waterproof, rainproof, and with snow protection. Temporary
protection should be taken when the equipment enclosure is opened for installation or maintenance in an
outdoor environment. The equipment must not be opened for installation or maintenance in bad weather
(e.g. gale, storm rainfall, extreme temperatures and high humidity)
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.
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.
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.
Power Supply
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

3.2.2 INSTALLATION CHECKLIST
Working space available for installation and maintenance for each mounting arrangement. Ensure
unrestricted airflow.
Ensure earthing point is within reach of the ground wire.
Ensure a power source is within reach of the power cord and the power source has sufficient capacity.
Where appropriate, ensure unused RF connectors are terminated.
Do not locate the equipment near large transformers or motors that may cause electromagnetic
interference.
Reduce signal loss in feeder cable by minimizing the length and number of RF connections.
Ensure VSWR of antennas system < 1.5:1.
Ensure equipment will be operated within the stated environment (see datasheet)
Observe handling of all cables to prevent damage.
Donor antenna should have a narrow beamwidth and positioned in line-of-sight (LOS) to donor BTS
site so that the donor signal level is maximized. This allows the use of minimum gain to achieve the
maximum DL output power. The UL gain is typically set lower than or equal to the DL gain to minimize
noise interference to the donor BTS
Service antenna should be selected based on the type of service area, e.g., indoor antenna for indoor
application, and panel antenna for outdoor application.

3.4.3 GROUNDING CONNECTION
Ground Connection
To ensure safe operation of the product, a ground (earth) connection is required. For single phase AC
power source, the product must be grounded by connecting the “earth wire” of the power cord to the ground
terminal of the AC supply. For operating this product with DC power system (such as rectifiers), the product
should not be connected to power systems that switch open the return lead because the return lead could
function as the ground (earth) connection for the equipment.
Protective Ground Connection
The enclosure must be grounded securely by connecting a copper wire (CSA 16mm2) to the grounding
terminal on the equipment/rack, and the other end to a protective ground (i.e. building earth point). An
internationally acceptable colour code of the ground connection wire is green/yellow.
Such a ground connection implements the “Protective Ground Connection”, and must be connected to the
equipment at the designated ground point. In general, do not connect the supply before establishing an
adequate ground (earth) connection.
Construct the ground wire, and use appropriate crimp connectors where necessary. Locate and connect
the equipment grounding terminal to a protective ground (i.e. building earth point).
3.4.4 RF CABLE CONNECTION
Single band PS BDA RF cables connection is as follows:
PS BDA MT port Connects to the feeder cable from service antenna.
PS BDA DT port Connects to the feeder cable from donor antenna.
3.4.5 ETHERNET CONNECTION
Connect Ethernet with ‘LAN’ port in the panel, Ethernet type only.

Table 3: Commissioning Task Explanation
Commissioning Tasks
Observation
1. On-line and Inquiry status
Activate the OMT Main window. The system Initialization will
completed in about 2 minutes.
Check the ALM LED for the repeater’s status. Proceed if there is no
alarm; else check the failure and attend to the alarm.
2. Isolation detection
Detect isolation of service antenna and donor antenna.
3. Set Channel No.
Keep RF switch ON and set the channel number of the repeater’s
operating frequency.
4. Adjust Downlink Output
Power and align donor
antenna
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.
5. Configure [Device ID]
Go to [Device Info] and set [Device ID].
6. Comm. Setting
Go to [Management] -> [Comm. Setting] and select communication
types: [SMS], [PS] or [SNMP].
7. Select Monitoring
Parameters
Select the equipment controlled and monitored parameters..
8. Test coverage area field
intensity and adjust service
antenna.
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.
9. Verify UL gain and ensure
test call produces good
voice quality and there is
no interfering BTS
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.
