Multi-band 850/1800/2100MHz Mobile Signal Booster Amplifier Repeater
A cell phone booster is a device that gathers the signal from the air, usually through an outdoor unit (such as an antenna), and “conveys” this signal to an indoor unit that is supposed to boost the signal. This conveying is done through a wired connection between the outdoor antenna and the indoor unit. The indoor cell phone booster, in turn, is provided with external power through a power outlet and has a complex circuitry that allows it to amplify the weak signal that has been received by the outdoor antenna. The indoor unit then sends the electrical signal to the indoor antenna that is directly connected to the unit, and the antenna converts the electrical signal to waves of the same frequency as were received by the outdoor unit. This, the frequency range of the waves does not change, and the cell phones do not notice any difference, except for a dramatic increase in the signal power that they are receiving.
Thus, as we can see, cell phone signal boosters are devices that literally boost the cell phone signal that you are receiving. This is done through some complex circuitry that works through the use of external power and boosts the signal to usable levels.

How It Work?
The outdoor antenna installed on the roof receives mobile phone’s signal and transmits it to the amplifier host through coaxial jumpers. The host amplifies the mobile signal and transmits it to the indoor space through the indoor antenna.
No inter-linkage between coaxial cable and mobile phone is needed, and mobile phones inside the house can get better mobile signals.
Product Description
How it works?
1. Received a good outdoor signal from signal tower. 2. Cable transmits good signal to repeater. 3.Signal Booster enhance the received signal. 4.Improve indoor's cellphone signal.

Signal problem & installation technique supporting
1.If still weak signal receipt after installation, please check if outdoor antenna point to signal tower correctly or elsewhere has stronger signal and confirm signal strength achieve-70DBM.
2.If still have no signal after installation, please check our device power adapter whether connected perfectly? And connectors connect well.
3. If strength is not steady, please check if outdoor and indoor antenna is too close; please ensure outdoor antenna has distance of 10 meters at least, with a barrier and not in a same horizontal line.
4. Packed the outdoor connector by waterproof glue, otherwise wet reduce the signal cover area.
