1. Introduction
1.1. General Introduction
As an equipment to clear the shadows inevitably generated among the adjacent cells of
WCDMA and GSM, PWDB-GW simultaneously supports both WCDMA and GSM and
effectively repeats the signals between terminals in dead area and BTS
The main objectives of PWDB-GW are as follows:
- The expansion of service coverage
- The enhancement of service quality at the specific areas such as in tunnel or in-
building
- The enhancement of signal strength at the places where the signal is weak
2. Network configuration of system
2.1. Network configuration
PWDB-GW repeater is an equipment to clear the shadows and fill the gaps existing
among the adjacent cells and enhances the quality of services by extending coverage of
WCDMA and GSM.
The above architecture is for the case when the MHU is co-located with BTS (GSM or
6 / 40
WCDMA), and the service is provided remotely.

4.1.4. Descriptions of PWDB-GW MHU
[Forward Path]
The signal from GSM or WCDMA BTS is fed to the RF input port of MHU rear side.
Initially, in the MHU RVS/FWD COMbiner(MRFCOM) module, the input signal power
level is measured and combined with the modem signal(360MHz), and it becomes the
input signal to the optic module to be transmitted to RU.
[Reverse Path]
The WCDMA or GSM RVS signal input from RU through the optic module is divided
into RF and modem signal, and RF RVS signal level is measured by the MRFCOM
module, which becomes the input signal to the BTS of GSM or WCDMA.

4.2.4. Description of PWDB-GWRU
[Forward path]
The RF and modem signal sent from optic module of MHU is first divided into RF and
modem signal at Divider in RU, then the CDMA RF signal is amplified and filtered at
the RFBS module and the modem signal is conveyed to CPU of NMS controller through
FSK modem.
The CDMA RF signal input from the RFBS module is linearly amplified up to high
power level on HPA, passed through the Front-End Filter Unit, and finally transmitted
through an antenna.
[Reverse Path]
CDMA Rx signals incoming from an antenna are first passed by the Front-End Filter
Unit, amplified on a low noise and high gain performance and filtered on RRLNA/RRBS,
and combined with modem signal at combiner(RRCOM). The combined signal is
transmitted to MHU through the optic module.

OUT PWR: Output power level of HPA(box)
OUT UPR: Display/control of upper threshold of HPA output
power(button), alarm status(LED)
OUT LWR: Value/control of lower threshold of HPA output
power(button), alarm status(LED)
ALC: Set ALC level for HPA output, and shows ALC status.
ASD(Auto Shutdown): ASD level(button), and running status
of function(LED).
36 / 40
ASD On/Off: When input upper threshold alarm is occurs,
set ASD activation, and shows its status.
Pilot On/Off: Set CW signal generation, and shows its
status. It is used for RVS gain setting.
IN PWR: RVS input power value of RRBS
IN UPR: Set RVS input upper threshold, and shows the
alarm status of input upper threshold RVS.
OUTPWR: RVS RF output power of RRBS
ATT: Set ATT to control RVS gain, and shows it’s value.
Center Freq: Set the RVS Center frequency value, and shows
PLL alarm status

6.8.5. Firmware download
Download of firmware is normally required when functional upgrade is needed or
when bug or erroneous actions of firmware are fixed.
Downloading improper images (executable file of repeater CPU) may cause seriously
harmful damages to equipment.
Download takes the following steps.
① Convert firmware source file (*.bin) to a downloadable file format.
Main menu: Action → Image Compression, toolbar:
② Open a pop-up window showing the status of the target equipment for firmware
download.
Method 1) Main menu View ¡æ Select Donor Windows or Remote Windows
Method 2) In Block View Dialog window, select Donor Windows or Remote Windows
③ Download firmware to the target equipment.
Method 1) Main menu Action ¡æ select Image Download menu
Method 2) In toolbar, select
for MHU, and select for RU
After that, download firmware after selecting the firmware file for the target
equipment.

6.9. Additional features
6.9.1. ASD (Auto Shutdown) Function
1. If the power level is above the shut down level for longer than 1 second, turn off
HPA.
2. During shut down state, monitor RFCHS output power. If the level is below 5dB from
shut down level, turn on HPA automatically.
3. Monitor HPA output power in normal operation, and monitor RFCHS output power
during shut down.

6.9.2. ALC (Auto Level Control) Function
1. If the power level reaches the ALC level, prevent to increase more than ALC level by
using ATT control.
2. By memorizing the existing ATT value, the ATT value before ALC can be reused even
when the power is reduced.
No ATT change
