How a signal booster works ?

A cell phone booster works by pulling in weak signal, boosting it, and then rebroadcasting it inside your area in need. Most signal boosters are essentially a three-part system: an outside antenna to capture weak cell signal, an amplifier to boost the weak signal, and an inside antenna to rebroadcast the enhanced signal inside your home or car. The outside antenna is the first major component of a cell phone booster. Usually mounted high on the roof or fascia of the house.

Cell Phone Signal Booster Introduction:

Signal Booster GW-17GDW-NH is designed to enhance and improve the quality of three band GSM 900MHz / DCS 1800MHz / WCDMA 2100MHz connection. There’re black and white colors for options. This model is enough to provide reliable coverage of signal in the area of up to 800 m². It is recommended to use in offices, apartments, houses etc.

The model is equipped with an LCD screen in a nice and symmetrical body, which displays the current level of input signal. The information on the LCD screen, greatly simplifies the process of adjusting the gain of the system. The connectors under the screws allow to build device on a wall or other vertical surface.

Cell Phone Signal Booster Instructions:

FAQ:
1. After installing booster signal not be very good, indoor signal coverage very small ?
> Adjust outdoor antenna's location and direction
> Change another high gain outdoor antenna
> Check whether cables are connected well
> Change more powerful repeater

2. Cell phone signal full bar, but communication quality bad ?
> Much closer distance between indoor and outdoor antenna, separate them with a longer distance.

3. After installing booster not only signal be good, but also more bad ?
> Much closer distance between indoor and outdoor antenna, separate them with a longer distance.

4. Working good for long time, suddenly signal bad ?
> Check whether outdoor cable connectors are flooded
> Check whether power light is working normally
> If cables are not flooded and power light is working normally, the booster should has problems and need to be sent back to factory for repair.
