LCD Screen Dual Band Cell Phone Repeater 23dBm 900MHz 1800MHz With ALC Control
Model. GW-23GD-N
Cell Phone Repeater Description:
A survey about dropped calls
A survey shows that 88% of people used cell phones. 72% of these experienced occasional dropped calls. 32% experienced this problem quite a few times a week. 55% of these used their cell phones to access the internet. But 77% were dissatisfied with their download speeds. 46% encountered frequent slow download speeds. Moreover, such problems were found to be more prevalent in smartphone owners.
Another survey shows what people are doing to improve their cell phone’s poor signal reception. While 97% of cell phone owners prefer indoor calling, 64% of them have taken steps to improving their situation and 32% are found to have adapted extreme moves such as running to the window or even moving outside while on call.
Cell Phone Repeater Introduction:
Signal Booster GW-23GD-N is designed to enhance and improve the quality of mobile 2G GSM900 connection.There’re black and white colors for options.
The gain of the model is 75dB, the power is 23dBm, which is compatible with all domestic operators of mobile communication. It is ideal for using in houses, offices, shops and restaurants.
The model is equipped with an LCD screen, which indicates the level of input signal before and after boosting. The information on the LCD screen, greatly simplifies the process of adjusting the gain of the system.

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.
