systems in small medium businesses and home users looking to enhance indoor wireless connectivity. It is


connected via coaxial cable to Donor Antenna and Service Antenna, Donor Antenna is placed outside the


building where it has easy access to BTS signal, and the Service Antenna is placed in the building where it


can extend radio coverage to the blind area. 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. 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.





Cost effective solution for weak signal zones, reduce drop/off calls.


Compact size, low power consumption,


easy installation, great cover.


Expansion and extending of the signal of base station.


Optimization of the quality of the signal and source


Cover about 500~3000m² without block or obstruct.


High linear design, ALC function design, low interference to BTS.


Support any cellular devices (voice & data & video)


Wide band signal booster, or customize selective band booster.


Support three wireless systems


Extended phone battery life. (Your phone does not need to put out as much power due to improved reception.)





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.
