Detailed Product Description
GSM 900 ICS Pico Repeater
Model: KR-1575GI
Introductions:
The GSM 900
ICS PICO Repeater is designed to provide a more cost-effective solution than adding
a new Base Transceiver Station (BTS) to improve signal coverage and
communication quality in GSM 900 system. And its easy installation and
maintenance can help carriers get fast return.
The repeater
is working as a relay between the BTS and mobiles. It receives the low-power
signal from BTS via the Donor Antenna, linearly amplifies the signal and then retransmits
it via the Coverage Antenna to the weak/blind coverage area. And the mobile
signal is also amplified and retransmitted to the BTS via the opposite
direction.
Features:
n High
system gain
n Plug-and-Play
n 30dB Adaptive Echo Interference Cancellation system
n Linear
power amplification to effectively suppress inter-modulation and spurious
emission
n Smart
Automatic Level Control (ALC) ensures output level stable and adjustable
continuously
n Adopting filter with highly selectivity and
low insertion loss eliminates interference between uplink and downlink
n Working frequency bandwidth adjustable
Applications:
To
expand signal coverage or fill signal blind area where GSM 900 signal is weak
or unavailable.
Indoor: Hotels, exhibition centers, basements,
shopping malls, offices, parking lots, etc.
