End of Section ENU STATUS : 1-0-0 Copyright - refer to title page Page 10 USER MANUAL FOR MBDA-200 2 EQUIPMENT DESCRIPTION 2.1 SYSTEM DIAGRAM Figure 2: System 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 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.

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 7. Select Monitoring Parameters 8. Test coverage area field intensity and adjust service antenna. 9. Verify UL gain and ensure test call produces good voice quality and there is no interfering BTS 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. 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.
