Ok so maybe huge is a bad word. Lets try interesting.
I have been challenged to build a wireless network for my church. When completed it should cover our entire property. I can not go with a wired network because I have to cross a city street. I do not think the city would lime me much If I trenched a line accross 4 lanes of traffic.
Here is a crude drawing of our property:

All dimensions are in feet.
The office contains the DSL line, so we have to start from there. My idea is to shoot out the window of the office with a cantenna into the steeple of the church. Inside the steeple, I would place a large omni directional antenna connected to a wireless repeater (WAP11). Now if I can't get enough signal shooting into the steeple I would have to go repeling on the church which is a good 60 feet off the ground.
I hope this would provide enough coverage for the entire area.
I have built several wireless networks before, just none this large. Any information would be helpful.
