All I can say is... WOW! For a couple years, I've headed ConnectedCadillac, an organization dedicated to providing free WiFi hotspots around downtown Cadillac. My eventual goal was to provide free WiFi access to the entire downtown district. Today, I approached the city about putting a hotspot at the most central downtown park. They asked me to put together a proposal not just for wireless-ing (is that a word? ) the park, but the entire downtown district! I told them that although I haven't done such a large-scale hotspot, I'd see what I could put together. I haven't done much research on the issue yet (I'll hit Google right after I finish typing this post) but I figured that someone here might have some insight as to where to start. Our downtown district is well under a mile square (probably about a half mile long by a quarter mile wide) but it's certainly not going to be covered by a simple router and a few extenders. If anyone here has worked on a project similar to this, I'd love to hear any advice you could give! Mean time, I'm off to Google... and wish me luck!
