400M 2W Band Selective RepeatersKT-CRP-B5-P33-B

    Kingtone Repeaters
   kintone repeater 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 lowpower 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.
 Telephone repeater
This is used to increase the range of telephone signals in a telephone line. They are most frequently used in trunklines that carry long distance calls. In an analog telephone line consisting of a pair of wires, it consists of an amplifier circuit made of transistors which use power from a DC current source to increase the power of the alternating current audio signal on the line. Since the telephone is a duplex (bidirectional) communication system, the wire pair carries two audio signals, one going in each direction. So telephone repeaters have to be bilateral, amplifying the signal in both directions without causing feedback, which complicates their design considerably. Telephone repeaters were the first type of repeater and were some of the first applications of amplification. The development of telephone repeaters between 1900 and 1915 made long distance phone service possible. However most telecommunications cables are now fiber optic cables which use optical repeaters (below).

Cellular repeater
This is a radio repeater for boosting cell phone reception in a limited area. The device functions like a small cellular base station, with a directional antenna to receive the signal from the nearest cell tower, an amplifier, and a local antenna to rebroadcast the signal to nearby cell phones. It is often used in downtown office buildings.                                                                                                                                                                                                                                                    


Main Features of kingtone 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;


TETRA 400 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.
