Below model for GSM900mhz 2G network ( IGC and ALC function ) may work under conditions :
1. bad outdoor signal at -80dbi to -85dbi around ;
2. No need wall to 100% insulate indoor and outdoor ( but if both antennas are too close ,it will not work too ) ,
Above models is only possible to work if outdoor signal is not good (-80dbm) ,does not mean 100% to work if really bad outdoor signal ( because a booster will take many conditions ) .
When you buy them it means that you just want to take try ,if does not work ,please be friendly to solve. If you are going to direct dispute or negative, please dont buy .
