Hi, All:

I have a camping ground that I want to provide broadband internet access.

First of all, I want to determine how many APs do I need. I know it depends on many factors such as radio cards and antenna. Any guideline for calculating this? The radio cards I am considering is either CM9 or SR based.

For WDS hotspot, I want to centralize user database using User Manager. I want to use just one hotspot AP controller. For each AP running WDS, is one wireless interface sufficient to serve clients and backhaul traffic to the hotspot AP controller? Can any one provide me an example?
