Detailed Product Description
GSM & DCS &
WCDMA Tri-Band Outdoor Repeater
Model: KR-4090GDW
Introductions:
The GSM&DCS&WCDMA
Tri-Band RF Repeater (RFR) 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 GSM900&DCS1800&WCDMA system. And
its easy installation and maintenance can help carrier 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 Band-Selective
RF Repeater: to amplify all signals in the whole band (bandwidth is customized)
n Aluminum-alloy casing with IP65 protection
has high resistance to dust, water and corroding
n Highly selective channel selector can process1
2 channels simultaneously
n No interference to BTS by adopting linear
amplifier with high gain and low noise
n Adopting filter with highly selectivity and
low insertion loss eliminates interference between uplink and downlink
n USB or RS-232 port provides a link to a
notebook for local supervision or to the built-in wireless modem to communicate
with the NMS (Network Management System) that can remotely supervise repeater’s
working status and download operational parameters to the repeater
Applications:
To expand signal
coverage or fill signal blind area where signal is weak or unavailable.
Outdoor: Airports, tourism regions, golf courses,
tunnels, factories, mining districts, villages, etc;
Indoor: Hotels, exhibition centers, basements,
shopping malls, offices, parking lots, etc.
