Close, I'm considered Delaware County... eh, best bet would be to punch in
19342 or Glen Mills into Map Quest for an approx idea... It says from my
house to the center (I'd imagine) of west chester is: 8.14 miles. I'm
looking at a page with 24dB gain antennas using Proxim base stations for a
3-5 mile radius. It sounds like willing participants will have trouble
complying with the projects guidelines if the hardware requirements aren't
broad enough... Let's see how things go with Dell though, I guess...

There are no hardware requirements. The Dell stuff I'm going to be experimenting with will be to offer a turn-key solution to people who don't want to get their hands dirty. The real requirement is what standards your kit supports. If your kit supports IPv6, OSPF and at *least* 802.11b (others can be added for back haul connections) then it will probably work.


Also how much is a block of IPs exactly (let's say a class c network).

Not applicable. We're not talking about IPv4. We're talking about IPv6. I have some influential backing behind getting a large block of IPv6 addresses to work with so don't worry about it, it's covered.


From my site surveys, it seems to me that the most useful things we need right now include:

1) Roof top access to some of the taller bldg's on the Philadelphia city skyline. I can see some of the tall ones in Center City pretty well from the suburban sites ~15 miles away.
2) Someone with deep pockets and a pioneering spirit to help facilitate the installation of key repeaters. Especially in high parts of Center City.
3) Early adopters who are willing to put up some quantity of cash less than $1000 to put an access point on their roof. The high cost is because of the need for multiple antennas this early in the project (one omni for local service, one directional for back haul).
4) Other early adopters near the first set who are willing to put up some quantity of cash less than $500 (that's the goal, anyway) to extend the usefulness of their local area portion of the mesh. Note that the local back haul connection needs to be in place before these smaller nodes are of any use.
5) Paypal donations to chris@yonderway.com will not be refused for the purpose of buying/testing gear and writing documentation on how to get this thing going. :-)


I'm buying precisely ONE of these Dell access points to see if this crazy idea will work on such cheap hardware. If it works, I'll get two to four more to set up a real prototype mesh, from which most of the solid documentation will come and the components for a few smaller nodes if someone wants to buy them when I am done with them. If this pans out, it will greatly reduce the cost of entry to extend the mesh.

I have some photos taken today from some of the highest points in Swarthmore and I'll get those up on my web site and post my notes later tonight.
