Sprint User Manual Digital TRI-Band Indoor Repeater 3/22 1. SUMMARY GRS-TRIR-SPR is an Digital RF repeater, which iDEN 800/900 and US PCS Band Service. This system has 90dB gain in the iDEN 800/900 band and PCS band respectively with 25dBm and 24dBm maximum power each GRS-TRIR-SPR receives RF signal from BTS and transmits it to the blanked and shadowed area, thus providing and improving voice and image data services. GRS-TRIR-SPR’s goal is to support BTS’s functions proportionately. GRS-TRIR-SPR communicates with BTS wirelessly, thus saving additional costs for its maintenance. GRS-TRIR-SPR consists of RF/IF part Module, PA Module, Wave Module, Digital Filter module, and I/O & Control module divisions, which are supplied with Alarm LED, thus providing quick and easy maintenance and troubleshooting of the repeater. This manual describes in general structure of GRS-TRIR-SPR, its application, maintenance and troubleshooting, installation and operation etc. This equipment is indoor use and all the communication wirings are limited to inside of the building. CAUTION RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN IN CORRECT TYPE. DISPOSE OF USED BATTERIES ACCORDING TO THE INSTRUCTIONS Abbreviation PCS : Personal Communication System RF: Radio Frequency BTS: Base Transceiver Station IF: Intermediate Frequency I/O : Input/Output
Sprint User Manual Digital TRI-Band Indoor Repeater 4/22 2. System Configuration 2.1 GRS-TRIR-SPR Service Organization GRS-TRIR-SPR decreases blanked and shadowed areas and extend cell coverage by re-transmitting signal. The signal is received from BTS via Antenna directly, thus excluding additional expenses for signal transmission (like cabling). Service organization of TRI Band(iDEN 800,900 and CDMA) In-building RF repeater is shown at the picture below. Donor Antenna is directed to BTS and being divided at Service Antennas are installed in the building and parking place. Pass Loss should be taken into consideration while dividing and cabling. <Pic.1> US PCS and iDEN 800/900 Service Organization

Sprint User Manual Digital TRI-Band Indoor Repeater 8/22 2.2.2 Downlink Path Downlink and Uplink Gain Budgets have similar structure. In case of Downlink Path, RF signal is received from Donor Antenna, and through FWD division, then the signal is transferred to IF division, where desirable Band is selected by Digital Filter. Selected Band is transferred to RF division again, and through FWD HPA, after that the signal is transmitted to User through Server Antenna. CDMA is used two attenuators for AGC compensation. AGC attenuation range of CDMA is 40dB. AGC attenuation range of iDEN 800/900 is 30dB.

In case of Uplink Path, RF signal is received from Server Antenna, and through RVS division, then the signal is transferred to IF division, where desirable Band is selected by Digital Filter. Selected Band is transferred to RF division again, and through RVS HPA, after that the signal is transmitted to BTS through Donor Antenna. CDMA is used two attenuators for AGC compensation. AGC attenuation range of CDMA is 40dB. AGC attenuation range of iDEN 800/900 is 30dB.
