Detailed Product Description
43dBm WCDMA Outdoor ICS Repeater
Model: KR-3090WI/ KR-3390WI/ KR-3790WI/ KR-4090WI/ KR-4390WI
Introductions:
The WCDMA ICS 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.
The Repeater is designed to provide a more cost-effective solution than adding a new Base Transceiver Station (BTS) to improve WCDMA signal coverage and communication quality. Its easy installation and maintenance can help carrier get fast return.
Features:
nAluminum-alloy casing with IP65 protection has high resistance to dust, water and corroding
nReal Time interference signal cancellation (Multi-path Fading, Feed-Back signal) greatly reduces system isolation requirement
n nICS function to prevent self-oscillation, enhance gain and coverage range, and reduce isolation requirement between donor antenna and coverage antenna;
n nHighly selective digital channel selector can process up to 12 channels simultaneously;
nNo interference to BTS by adopting linear amplifier with high gain and low noise
nAdopting filter with highly selectivity and low insertion loss eliminates interference between uplink and downlink
nUSB 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 mobile 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.
