Getting a good signal almost anywhere but home isn't difficult with my cell phone service, but getting a good one at home is a challenge. We will in a rural area and it isn't unusual to only get 2 bars, 3 at best. I took the time to mount Wilson's Signal Boost equipment both inside and outside of my home. I set it by the window just to see how well it would work, and I ended up with 5 bars. I then mounted it outside on the siding (I don't like clutter inside) using the long cable Wilson provides and got a full 5 bars as well. Unless you live in a really strange place, mounting it indoors should be sufficient for most people.
