    Dual Band 70dB Mobile Signal Boosters Cellular Repeater Amplifier


    Mobile Signal Boosters 2G 3G 4G Dual Band 850MHz / 2100MHz Cellular Repeater Amplifier


    The advantages of this amplifier include:


    LCD Display.


    Even a non-technical person can easily install and use this signal booster. The display shows all important information and prompts: input and output signal strength, installation details, power, AGC (automatic gain control), etc.


    Sleep mode.


    In the absence of incoming and outgoing calls and data transmission over the Internet, the LCD amplifier goes into sleep mode. This function helps to save energy.


    Automatic adjustment of operation.


    The amplifier can adjust the system gain and signal level. All this helps to avoid self-excitation of the device. If a problem occurs, the device will turn off automatically.

    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.

    Product Description



    Mobile phone signal repeater provides the ultimate solution in any area where cellular communications can not work well due to leak of signals. The repeater device features easy installation & operation, build-in indoor antenna and no interference.



    Technique supporting:


    1. If still no signal receipt after activated repeater,please check if outdoor antenna point to signal tower or elsewhere have strong signal and check if strength achieve -70dBm.


    2. If cannot call out,please adjust the direction of outdoor antenna.


    3. If the strength is not steady,please check if outdoor and indoor antennas are too close;please ensure the outdoor antenna and indoor antenna have distance of 20meters at least,with a wall between and not in a same horizontal line.



    It could also improve indoor electromagnetism environments, protract cellular battery life and reduce radiation of cellphones. A mobile phone repeater is ideal for house, home, office use.
