Sprint User Manual 3G Indoor Repeater 1. SUMMARY GRS-1924R-SPR is an Digital RF repeater, which improves PCS network. GRS-1924R-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-1924R-SPR’s goal is to support BTS’s functions proportionately. GRS-1924R-SPR communicates with BTS wirelessly, thus saving additional costs for its maintenance.
Sprint User Manual 3G Indoor Repeater 2. System Configuration 2.1 GRS-1924R-SPR Service Organization GRS-1924R-SPR decreases blanked and shadowed areas and extends cell coverage by re-trans mitting signal. The signal is received from BTS via Antenna directly, thus excluding additional ex penses for signal transmission (like cabling). Service organization of CDMA In-building RF repeat er is shown at the picture below.

Sprint User Manual 3G 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 PAM, after that the signal is transmitted to User through Server Antenna. Two attenuators use for AGC compensation.
Sprint User Manual 3G 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 PAM, after that the signal is transmitted to BTS through Donor Antenna. Two attenuators use for ALC compensation.

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 20cm during normal operation. The gain of the antenna is 2 dBi.
