5. Functional Description Of R4 Band Selective Repeater
5.1. General Description
The R4 Band Selective Repeater System is designed to provide outdoor
coverage and can handle signals up to two sub bands in any one of the
service bands, used around the World by various service operators. It
provides highly selective amplification in the pre-set band. The details of
operating service frequency bands are given below:

[The Customer is advised to refer to the packing note giving the details of
frequency band set & the bandwidths of different sub bands equipped in the
repeater: ony SMR80 Band is subject to this FCC application w/ FCC ID:S3CR4-40-S8]
• The repeater adopts duplex mode and bi-directional amplification for
U/L & D/L signals between the base station and mobile users. It has
been designed for outdoor applications to meet the requirements of
large number of users in the targeted area.
• It conforms to ETSI standards & safety requirements.
• The system can be incorporated with optional Remote Management
System (RMS). It enables status monitoring, remote configuration &
speedy maintenance.
• The system can be customized to meet the requirement of user for
coverage by making provision for radiating required RF power in the
DL/UL paths to achieve the coverage. The System is incorporated
with monitoring facility through USB port with easy GUI interface.
• It intercepts signals from the BTS through a DONOR antenna (highly
directional outdoor antenna) and distributes the signals to mobile
users after amplification through SERVER antennas (omni
directional) system in the D/L.
• In the U/L, the signals from the mobile users are picked up by
SERVER antenna and retransmitted to the BTS after processing &
amplification in the repeater.
