Hi, a colleague at work asked this question:

My local church want to get WiFi enabled in the whole of their offices and main church building. The offices and main building are in the same overall structure and so the signal does not need to travel outside to any other buildings outside this main structure.

Where would I start on such a project and what kind of repeaters are needed (and how are they set up) given that some of the walls are pretty thick. Do you still have one ADSL line coming in to router or are there some options of having two lines coming in so that they isn't a single point of failure. Am looking at fibre for the broadband for increased speed.

Any starting pointers appreciated.
