LTE Band VII 10W Band Selective Repeaters（KT-LRP-B70-P40-VII）
Main Features of kingtone 4G lte cellular repeater
◇ High linearity PA; High system gain；
◇ Intelligent ALC technology；
◇ Full duplex and high isolation from uplink to downlink；
◇ Automatic Operation convenient operation；
◇ Integrated technique with reliable performance;
◇ Bandwidth can be configured from 5-25MHz in work band.
◇ Local and remote monitoring (optional) with automatic fault alarm &remote control;
◇ Weatherproof design for all-weather installation;
Cellular repeater Applications
To expand signal coverage of 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, Packing Lots etc.
It is mainly applicable to such case:
The repeater can find an installation place which can receive pure BTS signal at strong enough level as the Rx Level in repeater site should be more than ‐70dBm;
And can meet the requirement of antenna isolation to avoid self‐oscillation.
