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.
