Then you'd have the booster... Those work well, provided you can get a signal somewhere in your house. You put a base station where it can get a signal, then place the transmitter in a central location... The base station takes the tower signal and sends it to the xmitter, which then provides service to your house.
The only key thing is that while the signal you'll get will be strong, it'll only be as good, speed wise, as what that base station can get. I think I got like 10-20 mbps when I had the booster. And you'll get that though your house reliably, without a weak signal.
I get a signal in my house. I posted the speeds above. If I can get 10-20 I can live with that.
