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.

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. 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.

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.

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. AGC attenuation range of CDMA is 40dB.
AGC attenuation range of iDEN 800/900 is 30dB.

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. The antenna(s) used for this
transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter.
