I'm scheming with some of my neighbors to set up a wireless "Neighborhood Area Network (NAN)." The plan is to get the $280 per month commercial DSL connection (6Mb down, 1.5 up) and share it wirelessly amongst 6 or more people in our neighborhood. I've been searching the web for information on how to do this, but I haven't found much info so far. Here's what I'm thinking I can do, but I'm not sure if it will work: One house has the DSL modem and a wireless router/access point. This house will have an external omni-directional antenna mounted on the roof. The router will do the NAT for the other users. The other participating houses will each have an external directional antenna aimed at the previously mentioned omni-directional antenna. The antenna will connect to a wireless access point, which will then connect their home network to the NAN. Obviously security is a huge issue, and I'll be looking into this as well. Any suggestions or advice?
