ap to ap to laptop question

Hi anyone, I have a remote piece of property a mountain between me and

the city. I am only in the planning stage, and I am working this out

legally, so no real issues here. Plus it only about 5 miles. So my

question is regarding ap to ap setup.

Whats the difference between ap client and ap bridge? What I want is:

whatever). One to the city and the other to my property.

my property, pointing to the mountain.

So what I want to do is have my laptop communicate via wireless to my

local AP, and any other computers I allow, (preferably doing dhcp, nat,

firewalling, etc for my side), and have my local AP acting as a client

to the city AP passing along my traffic as if I was in the main

building in the city.

What do I use for an AP on my property that will act as a normal AP for

my laptop, but also act as client for the AP in the city? And if I

have the local antenna attached to the local AP (pointing to the

mountain), do I also need

another antenna for my local communications?

Thanks so much,

Tek
