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.
GRS-1924R-SPR consists of RF/IF part 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-1924R-SPR, its application, maintenance and
troubleshooting, installation and operation etc.

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. Donor Antenna is directed to BTS, and being divided at Servic
e Antennas are installed in the building and parking place. Pass Loss should be taken into consi
deration while dividing and cabling.
