To let the signal booster work, it needs conditions :

1. please be sure that signal strength, outside of your house is good enough to enable booster to work ,

    what is good signal:

a). stand outside to check if you can make fluent call or not, if can’t, please don’t buy ,
     the signal booster can’t  work well.
b). Put your phone there to check its signal strengthness :
Android : setting→about phone→status→network ,dbm display shall be at -70dbm around ;
IOS : dial *3001#12345#*, dbm display shall be at -70dbm around ;
If less than -70dbm, for example -80dbm,-100dbm, it means the signal strength very poor, the signal booster can’t work,
 

For avoiding unhappiness, please contact with us, if you are not clear above, before place the orders,

We will give you a best solution to get the best signal .Thank you.

 

 

Display device (for reference)

The external power supply detecting normal display ----OK.

Internal power supply detecting normal display ----OK.
MMIC circuit detects normal display ----OK.
-50dbm signal input and detection to achieve full displayed.
LCD display function,can display signal strongness which it receives from outdoor antenna,
the signal bar will be full black if the signal is received very good.
 
 
Installation Approaches:
1) Fix up outdoor antenna on housetop or outside the window and point it to the signal tower.
2) Connect outdoor antenna to "BTS" port in repeater machine through cable.
3) Plug power adaptor into AC power socket.
4) Please adjust the direction of the outdoor antenna, until the signal booster have a good signal,
    it is very important.
5) Connect indoor antenna(s) to "MOBILE" port in repeater machine through cable also.
6)   Please ensure the outdoor and indoor antennas have distance of 10 meters at least,
    with a wall between and not in a same horizontal line.

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.

 

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.

 

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.

 

 

Technique Supporting:

1) If still no signal receipt after activated repeater,please check if outdoor antenna point to signal tower

or elsewhere have strong signal and check if strength achieve -70DBM.

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 antennas have distance of 10 meters at least,

  with a wall between and not in a same horizontal line.
