Actually go read your contract. They do not guarantee signal indoors. After applying a radiant barrier to our attic we got horrible coverage. This will be great.
Also dont blame Verizon. Chances are AT&T and Sprint all share the same tower. Cities regulate where towers go and even where I live Verizon wanted to get a tower up another 10 feet, but the nimby's complained and some of us who would of gotten improved coverage lost out.
The only real benefit to Verizon is that when people are home they'll not be hitting the towers so much.
