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. 5MHz, 10MHz, 15MHz Blocks Three continuous 5MHz, 10MHz, 15MHz block combinations ( only continuous ) See page 10 for more details. 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. Functional Abbreviation PAM: POWER AMPLIFIER MODULE LNA: LOW NOISE AMPLIFIER AGC: AUTO GAIN CONTROL ALC: AUTO LIMIT CONTROL Caution: Risk of explosion if battery on the controller board is replaced by an incorrect type. -.Caution: Any changes or modifications to this device not explicitly approved by manufacturer could void your authority to operate this equipment. -.Warning: Exposure to Radio Frequency Radiation The radiated output power of this device is far below the FCC radio frequency exposure limits. Nevertheless, the device should be used in such a manner that the potential for human contact during normal operation is minimized. In order to avoid the possibility of exceeding the FCC radio frequency exposure limits, human proximity to the antenna should not be less than 20cm during normal operation. The gain of the antenna for pcs Band must not exceed 12 dBi. Sprint User Manual 3G Indoor Repeater 2.

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.

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. Verification of upper-level NMS operation status 18 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. In most cases of major repairs, GST will simply replace the unit and conduct repairs at the appropriate facility. 4.2.1 Necessary Testing and Measuring Equipment a. RF Power Meter: 10Watt Max, 50ohm b. Signal Generator: 3GHz c. Spectrum Analyzer: 3GHz d. Multi-Meter 4.2.2 Notice a. Troubleshooting should be performed by a trained technician. b. Parts that seem to be not used should not be disassembled. c. While troubleshooting, technician should use attenuator to check RF Signal output. 4.2.3 Simple Troubleshooting Method a. Verify LED Status, both on external LED’s as well as internal module LED’s - Normal operation: Green light On. Alarming: Red LED on b. Technician should check external and internal connectors to ensure that all connections are tightly secure. These connectors should be cleaned regularly. c . If technician thinks there is a serious problem, call after sales team for over-thephone technical support. 1-866-9-GST-USA 19 (1-866-947-8872) Sprint User Manual 3G Indoor Repeater 4.2.4 Troubleshooting Guide Item Check Point Trouble shooting Input Level Note before system * System Input power range Downlink -57dBm/Total ~ -37dBm/Total Uplink -57dBm/Total ~ -37dBm/Total operation Note before system * System Gain operation Gain Downlink 52 ~ 72dB Uplink 52 ~ 72dB Note before system * Output power at Server port operation Output power Downlink 15dBm/Total Uplink 15dBm/Total * Please check quantity of all accessories with specification Check in Advance * Check points before open for service before you set up. * Fit cable length in accordance with field condition. * Set up 1900MHz CDMA Donor antenna to secure Isolation (More than 79dBc) * Check following status - Verify that the antennas are securely mounted and pointed in the correct directions - Connection status between antennas and RF cable Check after open * Check points after open for service - Verify that the Repeater is securely mounted - Proper AC power status - Grounding status of electrical circuit - Coaxial cable (RF) construction status - Connectors and combiners connection status - Cable connection status against leakage of water 20 Sprint User Manual 3G Indoor Repeater 4.2.5 Troubleshooting Guide Related to RF Symptom When repeater does not work properly Check Point * Check Electricity Cord connection status Troubleshooting * Re-plug in Adapter cord * Please Check following status - Proper maximum output power limit level When in alarming - BTS input level (Spectrum Level) * DL over-input alarm - Input RSSI value on Status Page - Downlink Attenuation level * Please reset Adapter upon completing Alarm troubleshooting When in alarming When in alarming * Make sure output power is operating normally. * DL over-output alarm * Reset Adapter upon completing Alarm troubleshooting. * Please make sure output level is operating normally * UL over-output alarm * Please reset Adapter upon completing Alarm troubleshooting * Check following status: - Setting level of maximum temperature limit When in alarming * Temperature alarm - Temperature offset is normal or not. - Circumstances of temperature. * Reset Adapter upon completing Alarm troubleshooting When in alarming * Verify that the HPA’s are On. * RF OFF * Reset Adapter upon completing Alarm troubleshooting When output * Technician should verify * When Red light on the Shutdown LED, technician should power is no category of alarm at the front troubleshoot the alarm via Notebook computer. longer problem side of repeater. 21 Sprint User Manual 3G Indoor Repeater * Technician should connect When output antenna with output port of * Reconnect the connector. power is no repeater. * Change it if the connector is defective. longer problem * Please make sure all connectors are fastened When output power is no * Check the input level * Increase output power or check input change of BTS side. * Check Gain of the unit * If the Gain is different from normal level, please contact A/S longer problem When output power is no longer problem team.
