Product Description

27dBm 5 Bands Mobile Signal Repeater Boost 2G 3G 4G LTE Signals 3000m2 Coverage





1. This 5 bands mobile phone repeater is 27dBm high power, with 80dB gain, it can cover max 3000m2. 

2. Indoor Five Band Signal Repeater (Cell Phone Signal Amplifier) series is an ideal solution for three wireless systems in small / medium businesses and home users looking to enhance indoor wireless connectivity.

3. It boost 5 bands frequencies, such as LTE700, GSM900, DCS1800, 3G2100, 4G2600. 

4. And Automatic Gain Control (AGC) to avoid the Booster from over saturation, therefore maintaining a high voice quality and avoid adding interference to network. With good looking & super compact design also make it attractive.

5.. Besides, it is easy installation feature is also for individual customers to install the booster by themselves, and it does not need much professional knowledge and instrument. 





Digital Display Panel, Intelligent mode setting
Smart function called which can be activated via the digital display panel.
Users can choose gain and working system by LED Digital Panel.

Set the technical parameters simple and efficient, this is easier than DIP Switch.



POWER LED Green Normal
Off DC power problem
ALARM LED Green Sys-1,Sys-2 or Sys-3, working in linearity

There are strong input signal or severe self oscillation.

Attention: input signal level is too high or the space of donor antenna and service antenna is not enough. please adjust the gain, If the red light still turning on that means over accepting of donor antenna or strong interference, then please adjust the place of donor antenna.

Off Repeater breaks down, Please re-plug in and check if Alarm LED turns red, if it is, please take measures to keep Alarm LED green; if it maintains off, it means the power break down.
