Sprint User Manual 3G Indoor Repeater 1. Summary GRS-1915D-SPR is a 3G Indoor repeater, which has been designed to improve signals in blanket/shadow areas inside of buildings to transmit Sprint signals at PCS 1900MHz band. Characteristics PCS Band: 72dB Gain with 15dBm maximum composite output power. Bandwidth: Entire PCS 1900 frequency A Block to F Block (45MHz). Bandwidth selection adjustable per user’s situation.
Sprint User Manual 3G Indoor Repeater Characteristics GRS-1915D-SPR repeater is an indoor repeater with output power of 15dBm. modules are classified as below: - DPX Filters to combine the input/output signals for: CDMA - Body (the whole module) - AC/DC Adapter - Controller to monitor each module in repeater.

Sprint User Manual 3G Indoor Repeater 2.2.2 Downlink/ Uplink Path GRS-1915D-SPR improves and strengthens signals in PCS 1900MHz band. In downlink path, received from Donor Antenna signal is transferred through Duplexer (DPX) and Down Conversion (DNC) module, and after choosing one of 5MHz, 10MHz or 15MHz in IF path the signal is forwarded to Up Conversion (UPC) module. Then, improved signal is sent to Service Antenna through Diplexer (DPX). Uplink path is vice versa to Downlink path.

Equipment Needed for GRS-1915D-SPR Repeater Setup Parameter Item Quantity Remark Major Component GRS-1915D-SPR 1 EA Provided by GST CD which contains User Manual 1 EA V0.1 and Installation Guide V0.1 Additional Components Ethernet Cable 6.6ft 1 EA AC/DC Adapter 1 EA Ground Cable 6.
Sprint User Manual 3G Indoor Repeater 4.1.2 System Setup 1) This equipment is basically wall mountable. 2) Installer will have to connect the power supply (after verifying the input power) and RF cable to the Repeater and then it will be ready to use. 3) For grounding, there is a grounding terminal in main power supply which will be plugged into power outlet. There is also a separate grounding terminal on the repeater which should be connected to the on-site grounding terminal to ensure proper grounding.
Sprint User Manual 3G Indoor Repeater 4.1.3 Open for Service 1) Check points before open: a. Verification of system installation status: - Electricity, In/Out antennas, cable connection, and equipment mount status. b. Verification of system accessories: - User should check all necessary accessories. c. Check receipt signal level - Installer should check whether environmental conditions are in accordance with system specification to ensure that system operation will be optimized.
Sprint User Manual 3G Indoor Repeater Front LED b. Verification of operation status User should verify following status with Output monitoring terminal, which is provided by Spectrum Analyzer: - Output power generation status, system spurious emission characteristics. c. Verification of signal quality and strength in service area User should verify signal strength and quality of in-service coverage area by using cell phone or other measuring device. d.
Sprint User Manual 3G Indoor Repeater 4.2 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.
