Detailed Product Description

GSM & DCS & WCDMA&LTE Quad-Band Outdoor Repeater

Model: KR-3080LGDW

Introductions:

The GSM&DCS&WCDMA&LTE Quad-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&LTE 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.
