Product Description

33dBm 450MHz Channel Selective Tetra Repeater Signal Boosters with SMS Remote Control

 

GREETWIN Repeaters system is designed to solve problems of weak mobile signal, which is much cheaper than adding a new Base Station (BTS). Main operation of RF Repeaters system is to receive low‐power signal from BTS via radio frequency transmission and then transmit the amplified signal to the areas where network coverage is inadequate. And the mobile signal is also amplified and transmitted to the BTS via the opposite direction.
 

Main Features

High linearity PA; High system gain;

Support multi operators' network simultaneously

Intelligent ALC technology;

Full duplex and high isolation from uplink to downlink;

Automatic Operation convenient operation;

Integrated technique with reliable performance;

Local and remote monitoring (optional) with automatic fault alarm &remote control;

Weatherproof design for all-weather installation;

 

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 ‐75dBm;

    And can meet the requirement of antenna isolation to avoid self‐oscillation.

When you choose the channel number.

Please note,

460 + (N * 0.0125) = 460.9125MHz,

N is channel number. N = 73

 

460 + (N * 0.0125) = 461.1125MHz,

N is channel number. N = 89
