    Dual Band 70dB 4G Signal Repeater Mobile Phone Network Extender


    850/1700MHz 2G 3G 4G Dual Band Signal Repeater Mobile Phone Signal Extender Booster Amplify


    General
    The 850/1700MHz Pico Repeater provides an affordable solution to solve the indoor signal coverage problems due to signal fading and attenuation caused by architecture obstacles. 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 picks up the strongest signal from BTS via the Donor Antenna, linearly amplifies the signal and then retransmits it via the Indoor Signal Distribution System to the weak/blind coverage area. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction.

    How does it work?


    1. RECEIVES SIGNAL

    The powerful antenna reaches out to access a good signal, and delivers it to the booster.


    2. BOOSTS SIGNAL

    The booster receives the signal, amplifies it, and serves as a relay between your phone and the nearest cell tower.


    3. BROADCASTS SIGNAL

    Your devices get increased cell reception, and calls and data are fed through the booster back to the network.



    Packaging Including:


    1. Dual Band Booster

    2. 20 meters cable

    3. 5 meters cable

    4. Indoor Ceiling antenna

    5. Outdoor Log-periodic antenna

    6. Power adapter



    Installation Approaches


    1.Fix up outdoor antenna reception on housetop and point to signal tower;


    2.Connect outdoor antenna to “outdoor” port in repeater nachine through cable;


    3.Connect indoor antenna(s) to “indoor” port in repeater machinethrough cable also;


    4.Plug power adaptor into AC power socket and finish installation.
