  2. If can not call out, please adjust the direction of outdoor antenna.

  3. If strength is not steady, please check if outdoor & indoor antennas are too close. Please ensure the outdoor and indoor antenna have distance of 20 meters at least, with a wall between and not at the same horizontal line(outdoor antenna can be one floor higher than the repeater and indoor antenna).

How Booster/Repeater Works?

Repeaters are designed to fulfill the idea of one and main principle: to fill the areas with the weak or bad signal and to amplify these low signals in order to provide you with the communication suitable for you.

Reasons to Purchase Cell Phone Repeater.

1) The Signal Repeater provides the well-organized service that is why after installation of the system the quality of the connection will be really great.

2) Signal Repeater require no additional wires being attached to your cell phone thus allowing you to use your cell phone without any extra troublesome accessories, in other worlds, no physical connection to your cell phone.

3) They are practical, beautiful and easy to install. You will not need to hire anybody to provide the installation of the equipment. You will be able to install it by yourself using only the manual list attached to your repeater.

4) The system can be used by multiple phones. All phones that are under the coverage and are suitable for the frequency of your repeater can use the amplified signals.

5) Signal Repeater is able to cover different coverage: from small to large. In this case you can decide which of our repeater is suitable for your office or supermarket.

6) Repeater works at full duplex. It means that they not only receive the weak signal from the mobile base station and then divert to mobile phone after amplifier. They also receive the signal from your mobile phone and then send it to the mobile base station.

7) Our equipment is completely safe. Mobile repeaters do not produce any radiation.


Steps that describe the work of Repeater.

1) The outside antenna receives the signal from the nearest mobile base station.

2) The outside antenna sends the received signal through the coax cable to the installed Repeater.

3) The Repeater accepts the low signal and improves it.

4) The improved signal goes to the inside antenna through the connection coax cable.

5) The inside antenna send the improved good signal to your mobile phone.


The repeater makes the signal stronger in places with poor signal coverage such as:


1) Underground areas: basements, parking lots, tunnels;


2) Other places where cellular signal is shielded by metal or concrete walls: offices, supermarkets, cinemas, hotels;


3) Places distant from the BTS like private houses.
