Paul is in Haiti. Considering the recent disaster there, you can imagine the hurdles he's trying to overcome. I feel for him!
But it would be damn fun to do it!

I am assuming that since you are being pointed here, you are working to build a Wireless ISP. I assume by public frequencies you are referring to U.S. unlicensed frequencies. If not in the U.S. can you say which country? Rural areas have different meanings to different people. Some might consider farmland rural whereas I consider forested areas with little or no electricity or phone service rural. Would you mind expanding in more details what rural means to you? Where in the world is this deployment going to be? What is the terrain? Elevation changes across what distance? Foliage type and density? Population/housing density? Housing type? Houses per acre or sq mile? These are some of the questions that need to be answered to define rural. Minimal cost is always the goal with any start-up deployment. No electricity implies the need for solar or generator based POPs. Depending upon the area this can complicate deployment and potentially add significant cost initially and over time. I can think of five major components to the cost of a WISP. 1. The cost of equipment. 2. The man-hours to prepare, install and maintain the equipment. 3. The cost of bandwidth from one or more upstream providers. 4. The scalability of the system. 5. The subscriber base. (what they will pay, % that take service, churn rate, and competition) But there are many other factors that affect each cost. For example; if the terrain is flat with no foliage and you can build large tower in the middle of town its significantly cheaper to deploy infrastructure to cover the population. However if that same population of one town has hills every few miles, with 100-200 ft trees all over, and the county will not allow the deployment of towers then there is a much larger and more spread out infrastructure to cover the same number of people. This requires more man-hours, more sites, more equipment between sites and on sites, consideration of frequency re-use for scalability, more time to offer service to the whole subscriber base, etc and etc. Your statement of "using mainly open source software" stands out. There are not many open source options compared to proprietary options for WISP equipment. Equipment/software choice should be determined by looking at all options then determining what fits this environment best. Coverage area size and Scale are probably the biggest factors. Also very few WISPs rely on a single equipment vendor/type for providing service. You will also need to consider what level of service will be provided. For example are you offering 256kbps, 1.5mbps or 6mbps? Every plan is different and every area requires a different plan based upon what the operator of the WISP is trying to accomplish. What are you trying to accomplish and in what area are you working? Look up zip codes 95959 and 95945 to see the area I work with. These are just some of the thoughts off the top of my head. If I can offer anything further I would be more than happy to do so. Cheers, Matt Jenkins SmarterBroadband On 09/18/2010 03:51 PM, Robert West wrote: > Hey all.
