2.2.2. Downlink/ Uplink Path
The Smart-Cell repeater improves service in the 700MHz, 800MHz, 850MHz, 1900MHz,
2100MHz, 2500MHz and 2600MHz 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).
(except for 2500MHz-SMT-T33)
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)
