Page 3: Summary
1. SUMMARY GRS-1923D-SPR is an analog RF repeater, which improves PCS network. GRS-1923D-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-1923D-SPR’s goal is to support BTS’s functions proportionately. -

2. System Configuration 2.1 GRS-1923D-SPR Service Organization GRS-1923D-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. -

- Page 8 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 LNA division, then the signal is transferred to IF division, where desirable Band is selected by Digital Filter.
- Page 9 Sprint User Manual 3G Indoor Repeater 2.2.3 Uplink Path Uplink Path is similar in structure to Downlink Path. In case of Downlink Path, RF signal is received from Server Antenna, and through RVS LNA division, then the signal is transferred to IF division, where desirable Band is selected by Digital Filter.
