you can't be serious!

I've done designs for this (consulting). For crazy people.

Step one is the business model. Step two is easements. Step three is capital. Step four is return to step 1. Just ask Earthlink.

Now if you want to cover an RV park or some such, that's a viable story. But never as sensible as $13/mo DSL.

Can you be more specific about the right antennas?I can't find the right ones for building a citywide wifi network.

There is much more to think about than just what type of antenna you want to use. If you are trying to cover a city you need to think about things like back haul, wireless controllers etc.

Where I used to live there was a plan to try and cover the town with a mesh network using a bunch of these:

Never really got far beyond the initial testing stage.

Believe it or not, it's fairly easy to build a public wifi system, given enough money and a sound business plan.

The technical challenge is how to:

1) punch thru walls to get to your end users - they live in houses
2) the spectrum you're using for WiFi - it's a noisy space
3) site location - most expensive part

Citywide Wifi - check out Roofnet and more importantly, probably the best resource for this topic

best of luck. Remember, you're fighting against the big telco's and they have the financial resources, and their technology is better suited for Wide Area Networking.
