The T1 is up and running. It is assigning 192.168.x.x ip addresses.

We want to plug an access point into the switch.
We want an access point at my house which is 1km exactly and in clear line of sight to the location of the T1.
We also want another access point at my friends house which is visible from my house and about 1.5 kms away.

What do we need to buy? So far we have been told we need 4 access points (LinkSys WAP11s??). One at the T1, one at my house to get the signal from the T1, one more at my house to send the signal to my buddy, one at his house to receive the signal from me. Also, will we need 4 directional antennas to do this or just directional for the second and fourth access points above?

Thanks!
