2.1 SYSTEM DIAGRAM

In the downlink, the BTS signals are received by donor antenna of the repeater. After the duplexer, the

Figure 2: 2 Bands System Diagram for Example

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 via 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.

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 all cables are correctly and

securely connected, including power cables, grounding wires and RF cables.

 Check grounding connection and verify that the ground resistance is less than 5Ω.  Connect the equipment to the PC.  Power on equipment.  Monitor the initialization of the equipment though the LEDs on the panel. Refer to detailed LEDs

information in the next section.

4.2 LED INDICATORS

Diagnostic LEDs are located on the equipment front panel; each indicates the status of a particular function:

Commissioning Tasks

Observation

1. On-line and Inquiry status

 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.

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 [Equipment ID]

 Go to [Properties Info] and set [Equipment ID].

6. Comm. Config

 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.

7. Select Monitoring Parameters

 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.

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

maximmum 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.
