Coverage 5000 Sqm 3G 2100MHz Cell Phone Signal Boosters with LCD Display

Model. GW-27W-NH

How does a cell phone booster work ?

Cell phone signal booster is an device that help to improve the cell phone signal within an area. The outside antenna catches the low signal from the mobile base station and delivers it to the cell phone signal booster / repeater through the connection cable. After the signal is accepted by the signal booster/repeater, the device amplifies it. The amplified signal transmitted through inside antenna to the cell phone. The cell phone amplifiers work at full duplex, not only receive the low signal from the mobile base station then divert to mobile phone after amplifier. They also receive the signal from mobile phone then send to mobile base station after amplifier.

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.
