Air in a Barndominium

I have FWA and am going to lose it soon and will have to switch to Air. The problem I run into is I live in Barndominium. The best I get ant any window is one bar of service so the Air is not going too far well for me. Would it be possible to install a cell phone booster to boost the 5g signal in my house and have the Air get sufficient signal from the booster since it can’t get it directly from the tower?
