    The TETRA Fiber Optic BDA (Bi-directional Amplifier) is designed to solve problems of weak mobile signal in the place that is far away from the Base station (BS) and has fiber optic cable network underground.
    The system consists of two parts: Donor unit and Remote unit. The Donor unit captures the BS signal via direct coupler and closed to BS, then converts it into optic signal and transmits the amplified signal to the Remote unit via fiber optic cable. The Remote unit will reconvert the optic signal into RF signal and provide the signal to the areas where network coverage is inadequate. And the mobile signal is also amplified and retransmitted to the BS via the opposite direction.
    FOR is designed for both outdoor and indoor applications and the best suitable applications are for extending the coverage in large buildings (IBS), highways, tunnels and remote villages. FOR can be customized for single and multiple technologies.
     
     

    Mainfeature

    A.The advantages of the repeater are :

    • Low cost compared to a BTS
    • Easy installation and use
    • High reliabilit

    B.Hot Selling 3 Types Tetra/UHF BDA:

    • Tetra BDA Trunk Amplifier System
    • Tetra BDA Band Selective Repeater System
    • Tetra BDA Fiber Optic Repeater System

     

    Application&scenarios

    The Kingtone Repeater solution also allows :

    • to extend the signal coverage of a BTS in urban and rural
    • to fill the white areas in rural and mountainous areas
    • to insure coverage of infrastructure such as tunnels, shopping malls,
    • parking garages, office buildings, hangars companies, factories, etc ...
