Outdoor Repeater DCS1800mhz Network Output 5watts
The DCS1800mhz 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 GSM 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 receivers 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
1.Aluminum-alloy casing with PI65 protection has high resistance to dust, water and corroding;
2.No interference to BTS by adopting linear amplifier with high gain and low noise;
3.Adoption filter with highly selectivity and low insertion loss eliminates interference between uplink and downlink;
4.USB port provides a link a notebook for local supervision or to the build-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 blink area where signal is weak or unavailable
Outdoor :Airports ,tourism regions, folf courses, tunnels, factories ,mining districts ,villages ;
Indoor :Hotels ,exhibition centers ,basements ,shipping malls , offices ,parking lots ;
