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 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.

3. Set Channel No.
4. Adjust Downlink Output
Power and align donor
antenna
5. Configure [Equipment ID]
6. Comm. Config
7. Select Monitoring
Parameters
8. Test coverage area field
intensity and adjust
service antenna.
Table 6: Commissioning Procedure
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.
Detect isolation of service antenna and donor antenna.
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
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.
