******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 -90dbm to -95dbm around ;
IOS : dial *3001#12345#*, dbm display shall be at -90dbm to -95dbm around ;
-100dbm to -105dbm means bad,so please dont buy.

2. Please be sure the place where you are going to install is 1800MHZ

800MHZ(Band 20:Uplink:832 ~ 862MHz;Downlink:791 ~ 821MHz)

900MHZ(EGSM Band 8:Uplink:885 ~ 915MHz;Downlink:930 ~ 960MHz)

1800MHZ(Band 3:Uplink:1710~1785MHz;Downlink:1805~ 1880MHz)

2100MHZ(WCDMA Band 1:Uplink:1920 ~ 1980MHz ;Downlink:2110 ~ 2170MHz)

2600MHZ(Band 7:Uplink:2500 ~ 2570MHz;Downlink:2620 ~ 2690MHz)

3.  ( important )   Install them correctly to avoid interference ( auto osillation ), when interference exist ,

signal LED will be normal on,but phone can not make call or no signal displayed on phone, for small cars ,it is a big problem to solve  . 

Many buyers meet this problem , and can not solve it well
For avoiding unhappiness ,please do not buy before you are clear about the above .
