Sounds like you have some sort of fixed wireless solution. I was interested in this when I had my DSL taken away. Problem is nobody around here supports it. Sprint and AT&T seem to have the most support for this.

If anyone else is interested, these are the other two broadband solutions I explored:
-NovaRoam
-Homebrew SDSL (I would have run my own DSL line from my office to my house and mooch their bandwidth)
