Almost 5yrs no hiccups... Western Data Sy - San Antonio, Antonio TX - 6/15/2012 Almost 5yrs ago we purchased one of these for office. Our building has a brick facade on the front and one side but is corrugated metal on the other two sides and the roof. The building is approx 125ft-by-50ft in total footprint. Cellular signal in the interior was abysmal and on the side of the building where all the sales staff have their offices the signal was practically non-existent. After
