Sprint User Manual Digital TRI-Band Indoor Repeater 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.
Sprint User Manual Digital TRI-Band Indoor Repeater 2. System Configuration 2.1 GRS-TRIR-SPR Service Organization GRS-TRIR-SPR decreases blanked and shadowed areas and extend cell coverage by re-transmitt ing signal. The signal is received from BTS via Antenna directly, thus excluding additional expen ses for signal transmission (like cabling). Service organization of TRI Band(iDEN 800,900 and C DMA) In-building RF repeater is shown at the picture below.

Sprint User Manual Digital TRI-Band Indoor Repeater 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.

Sprint User Manual Digital TRI-Band Indoor Repeater 2.2.3 Uplink Path Uplink Path is similar in structure to Downlink Path. 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.

Sprint User Manual Digital TRI-Band Indoor Repeater 2.2.4 Frequency Selection GRS-TRIR-SPR IDEN800 BAND has 18MHz, 7MHz Paths in IF division, so any of these bandwidt hs can be chosen for providing service. Also, by adding Channel Select Function, it enables users to select band offset sophisticatedly. iDEN 800/900 Band can changed bandwidth to 4MHz at 200kHz step of right band edge.

MPE Information 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 30cm during normal operation. The gain of the antenna is 12 dBi.
