FCC Part 15.105 statement (Class A)
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant
to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment. This equipment generates,
uses, and can radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in which case the user will be
required to correct the interference at his own expense.
FCC Part 15.21 statement
Any changes or modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate this equipment.
Home/ personal use are prohibited
Use of unauthorized antennas, cables, and/or coupling devices not conforming with
ERP/EIRP and/or indoor‐only restrictions is prohibited

2. Introduction
2.1. System Overview
GST-IC-ELITE-1943 is designed to improve coverage and capacity of CDMA Band Class 1 and
LTE Band25 services in all shadowed and blanked areas of Sprint network.
GST-IC-ELITE-1943 receives and improves weak signals as cancelling the multi-path interference
even if there is a lack of isolation between Donor and Service antenna.
This solution does not request any costs for Backhaul installation, so will save OPEX and CAPEX.

5.1. Block Diagram
Figure 7. GST-IC-ELITE-1943 Block Diagram Configuration
The repeater improves service in the Sprint Network of CDMA Class 1 & LTE Band 25.
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 under lack of isolation between Donor and Service Antenna using
the ICS (Interference-Cancellation-System) engine.
The Repeater is consists of a ICM (Down and up converters with Digital Signal Processing (DSP) module),
Cavity filters and power amplifier. In Downlink Path, a weak RF signal is received from Donor Antenna.
being converted from RF to IF signal, It is transferred to the DSP&ICS block, where after digitalizing by
DA converter, signal is filtered by DSP. After filtering digital signal is converted into analog RF signal
via modulator and then transmitted to amplifier. Desirable signal is amplified and outputted through
Service Antenna. Uplink path works vice versa.

6.3. ALC/ AGC & Gain Balance Function
ALC means a function which controls gain automatically in order to protect H/W in case of
excessive out power more than user-defined threshold value upon Input RSSI change,
and to keep signal quality. AGC means UL Gain Balancing function based on DL Gain.
6.4. Smart AGS (Auto Gain Setting) Function
• Transmit the stable CDMA Pilot Power and LTE RS Power to use Smart ALC and CDMA/ LTE
Dual Modem
• Operate the BTS Coverage reliably
• Set the repeater gain correctly based on Path loss between BTS and Repeater, minimize the
increment of BTS Noise Floor
• If AGS function is close, system operate only Smart ALC function (able to control thru Web-UI)

9.1. Warnings and Hazards
9.1.1. Electric Shock
• Opening the Repeater could result in electrical shock and may cause severe
injury
• Operating the Repeater with antennas in very close proximity facing each other
could lead to severe damage to the repeater
9.1.2. Exposure to RF
Working with the repeater while in operation, may expose the technician to
RF electromagnetic fields that exceed FCC Rules for human expose.
Visit the FCC Website at http://www.fcc.gov/oet/rfsafety to learn more about
The effects of exposure to RF electromagnetic fields
9.2. Position Antenna
• After installing antennas, Installer should ensure line of Site
• Actual separation distance is determined upon gain of antenna used
So, maintain a minimum safe distance that achieved isolation 60dB
at least while operating near the donor and service antenna
• Antennas needs to be mounted outdoors on a permanent structure
• Antenna’s general specification is below
