I can tell u this. we bought one for the control room at work which is explosion proof and built out of every possible material that can effect cell signals plus lots of radio interference from control systems. we bought a cellphone-mate signal booster with 55 db gain and covers 2500 sq ft and went from 1-2 bars outside to 5 bars inside. worked great for $350. just ordered one for the house. signal was never a problem when traveling just when sitting at home and at work. solved all our problems. plus its dual band so it boosted me on sprint and my iphone flunkies as well
