2.2.2. Downlink/ Uplink Path
The Smart-Cell repeater improves service in the 700MHz, 800MHz, 850MHz, 1900MHz
and 2100MHz frequency bands. User may select frequency band according to the site
peculiarities. After receiving a weak signal from donor antenna, the repeater improves
and sends securely isolated signal out to service antenna.
Amplifier unit is designed for correspondent operation with digital filter module (DFM).
The AMP unit consists of a down and up converters, cavity filter and power amplifier
(PAU).
In Downlink Path, a weak RF signal is received from Donor Antenna. Being converted
from RF to IF signal, it is transferred to the DFM, where after digitalizing by DA
converter, signal is filtered by FPGA. After filtering digital, signal is converted into
analog RF signal with modulator. Transmit to amplifier. Desirable signal is amplified and
outputted through Service Antenna. Uplink path works vice versa.

4.4. Troubleshooting
In case of abnormal operation, technician should diagnose abnormality via remote
access or directly connecting to repeater using Ethernet cable. If technician is required
to conduct repairs due to major alarm, repeater should first be powered off, and then
technician should prepare the proper measurement equipment before trying to fix the
problem. In most cases of major repairs, GST will simply replace the unit and conduct
repairs at the appropriate facility.
4.4.1. Simple Troubleshooting Method
1) Verify LED Status, both on external LED’s as well as internal module LED’s
- Normal operation: Green light on. Alarming: Red LED on.
2) Technician should check external and internal connectors to ensure that all
connections are tightly secure. These connectors should be cleaned regularly.
3) If technician thinks there is a serious problem, call after sales team for over-the-
phone technical support. 1-866-9-GST-USA (1-866-947-8872)
