Detailed Product Description
WCDMA2100 Outdoor Signal Repeater
Model: KR-3090W/ KR-3390W/ KR-3790W/
KR-4090W/ KR-4390W
Introductions:
The WCDMA2100
RF 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 WCDMA2100 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:
Aluminum-alloy casing with IP65 protection
has high resistance to dust, water and corroding
No interference to BTS by adopting linear
amplifier with high gain and low noise
Adopting filter with highly selectivity and
low insertion loss eliminates interference between uplink and downlink
USB 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 WCDMA 2100MHz 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.
