******Important Note ( please read , and please read all descriptions carefully ) ************:
To let a booster work it needs conditions :

1. please be sure that signal outside of your house is good enough to enable booster to work , what good signal is:
a). stand there to check if you can make fluent call or not,if can ,then you buy ,otherwise please dont buy ;
b). Put your phone there to check its signal strengthness :
Android : setting-about phone-status-network ,dbm display shall be at -60dbm to -75dbm around ;
IOS : dial *3001#12345#*, dbm display shall be at -60dbm to -75dbm around ;

-80dbm to -100dbm means bad,so please dont buy

2. Please be sure the place where you are going to install is GSM 900MHZ 2g network AND 3g 2100MHZ , operator may use dcs 1800mhz for 2G network  .

3. Buy correct cable and anteana ,50ohm cable is recommended ,RG58 not recommended , for DCS ,3G,4G you must use 50Ohm cable ;
4. Install them correctly to avoid interference ( auto osillation ) with walls between indoor & outdoor antenna, when interference exist ,LCD will display full signal bar or signal LED normal on, but phone can not make call .

For avoiding unhappiness ,please do not buy before you are clear about the above .
