1. INTRODUCTION
Smart-Cell is a repeater, which has been designed to improve signals in blanket/shadow
areas inside of buildings to transmit Verizon’s signals at 700MHz, 850MHz, 1900MHz, and
2100MHz frequencies. User may choose filtering configuration according to the specific
site circumstances.
1.1. Warning
1.1.1 FCC Warning Statements
1) FCC Part 15.19 :
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions:
(1) This device may not cause harmful interference, and
(2) This device must accept any interference received, including interference that
may cause undesired operation.
2) FCC Part 15.105 :
This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following
measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the

Verizon User Manual
Smart-Cell Repeater

receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
3) FCC Part 15.21 :
Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate this equipment.
4) RF Exposure :
This equipment is not enclosing antenna and not demand specific vendor of
antennas. Use an antenna as operator’s guidance. But, the antennas must be
installed such that a minimum separation distance of at least 130cm is maintained
between the radiator (antenna) and all persons at all times. This device must not be
co-located or operating in conjunction with any other antenna or transmitter.
1.2. GST Smart-Cell Repeater Advantages
It provides selectable RF power levels for any wireless technology / band.
It has individual monitoring multiple technology.
FPGA digital filtering provides optimized RF performance.
It allows modification of technology via customer interface.

2. SYSTEM CONFIGURATION
2.2. Smart-Cell Repeater Service Network Configuration
Smart-Cell RF Repeater is designed for improving coverage and capacity of Verizon’s LTE
& CDMA services nationwide. The repeater can provide coverage for all troubled areas
such as suburban, shadow areas, backside of mountains, urban and metropolitan
locations.
GST products are easy to install, have remote status monitoring and control functions
(NMS System) via wired line and wireless modems.

2.3.2. 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.

4.1.1. Check points before turning on the Repeater
1) System Power Check
①AC electrical power to the repeater should be 110V, input electricity only after
power verification.
2) Input RF Signal Range
①Optimal input RSSI into the repeater is -57dBm ~ -27dBm for
700MHz/850MHz/1900MHz/2100MHz. User should verify input condition of
Donor ANT. If the input RSSI exceeds -27dBm, then external attenuators should
be used.

3) Isolation check between DONOR/SERVEICE ANT
①Isolation condition of this equipment is 105dBc (Gain+15dB). User should check
its condition before installation.
4.1.2. Open for Service
1) Check points before open:
①Verification of system installation status :
Electricity, In/Out antennas, cable connection, and equipment mount status.
②Verification of system accessories :
User should check all necessary accessories.
③Check receipt signal level :
Installer should check whether environmental conditions are in accordance
with system specification to ensure that system operation will be optimized.
2) Check points after open:
①Check external LED
RUN: Green light ON (Off: all lights off)
ALARM: Green light in normal status, Red light in alarming
SHUT DOWN: Green light in normal status, Red light in Shutdown status
