First, you need to understand why so many of these projects failed. Perhaps too much equipment was purchased, without first thinking about how it would be used. http://en.wikipedia.org/wiki/Municipal_wireless_network "St. Cloud’s muni Wi-Fi cloud is only partly 'cloudy' " http://blogs.zdnet.com/ip-telephony/?p=1046 "St. Cloud Sees Muni-WiFi Woes" http://www.techdirt.com/articles/20060424/090245.shtml "the download isn't great, around 2mbps, but upload is at least 4 times better than cable, at around 128kbps top speed" "The download speeds are a consistent 4 Mb and uploading is between 500-800 Kbps" So to start with, those are the kinds of rates you'll be offering people. There are limits to how many people can be supported. Some of your customers might receive different performance than others. ******* This site is purely for your amusement. This is *not* a practical part of any subscription service. But I like this idea, of private individuals doing their own distribution schemes. The enemy of this system is fog. And the data rate is too low to use for backhaul. http://ronja.twibright.com/about.php http://en.wikipedia.org/wiki/RONJA ******* You might also consider visiting an online bookstore, and see what books have been written on planning large scale wifi networks. Another alternative, is to visit your local university. Go to the electrical engineering department, and find a professor who teaches about radio technologies. That person may have a better understanding of the details. Finally, don't underestimate the problems caused by governments, laws, and monopolies. You might be almost allowed to finish the installation of millions of dollars of equipment, only to have a "stop work" order issued by a court. Make sure that there are no legal obstacles to competing with a monopoly telecom provider. Paul | |||||||||||||
