The house I just bought has aluminium siding and the GSM cell phone reception is terrible inside the house, outside the house has great reception, is there a cell phone repeater I can put in my attic (the roof isn't metal) to solve the issue?
 


Yeah, true. I need a system with an inside and outside antenna to cover about 1500 sqr feet, any suggestions?
 


I have cricket wireless, they don't have a preferred booster. How about a weboost system?
 


Except Cricket doesn't lease bandwidth anymore, because they were bought by AT&T a few years ago and use their network.
