So I've recently become employed at an orginization who does not have their computers networked together. I was shocked, at first, but then they explained that hard wiring a network in this building would be expensive. Naturally I suggested wireless, after all my cell phone (and everyone elses) works anywhere in the building, even in the basement. But this organization was told by an outside IT company that a wireless network would not work in this building because of the enormous amount of concrete. This is one of a handful of buildings built by a well known architect named Louis Kahn. All I would like to know is if a wireless system will work in a building made almost entirely out of concrete, and if not, why? - especially since cell phones do. Information and assistance are appreciated!
