INSTALLATION GUIDE FOR RX7W22 ENU STATUS : 1-0-0 Copyright - refer to title page Page 9 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.

INSTALLATION GUIDE FOR RX7W22 ENU STATUS : 1-0-0 Copyright - refer to title page Page 11 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.
INSTALLATION GUIDE FOR RX7W22 ENU STATUS : 1-0-0 Copyright - refer to title page Page 12 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.

INSTALLATION GUIDE FOR RX7W22 ENU STATUS : 1-0-0 Copyright - refer to title page Page 13 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 cables are properly routed and secured so that they are not damaged. Manual Handling During transportation and installation, take necessary handling precautions to avoid potential physical injury to the installation personnel and the equipment.
INSTALLATION GUIDE FOR RX7W22 ENU STATUS : 1-0-0 Copyright - refer to title page Page 14 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.

Table 2: LED Indicators Identifier Colour Indication PWR Green Power indicator. ON = power on; OFF = power off. RUN Green Operation indicator, flashes every second to indicate normal operation. ALM Red Alarm indicator. ON = alarm; OFF = no alarm. 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.

INSTALLATION GUIDE FOR RX7W22 ENU STATUS : 1-0-0 Copyright - refer to title page Page 21 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. End of Section
