Also, coming in a bit late, but I am beginning to think the best method for my reshalls anyway is to put an AP in every other room, as they run linearly down a hallway. Then stagger the floor above to offset by one room. We've been doing every 3rd room lately and while it seems adequate, I think for density purposes, as well as signal level, moving to the every other room makes sense in the long run. As someone else mentioned, power output levels are one thing, antenna performance is another and then one still doesn't know anything about the device's' receive sensitivity which is another factor in the RF realm.
