This is my very first post, little did I know how interesting all the information I have found was going to be when I typed 'wardriving' into Google that I had found on a page that did not describe its meaning !!

Now I have read enough posts on the forum to know that I will get shot down in flames if I do not do some legwork. This I am willing to do but I need a starting point like 'you need to find/calculate X'

I need to create a wifi link between an AP and a laptop that can communicate within a realitivly large building. I cannot specify how big but it would be upto say four floors within a max 50m footprint or typical office/hospital type building as this setup would be used only for a few days at a time at any one building. The laptop is likely to be used in most cases in a few set locations from the AP and comms needs to be setup quickly i.e: time=money. The AP is most likely to be situated within a plantroom on the basement, ground or top floor of the building.

Would just a cantenna type arrangement work if you could remember roughly where the AP is in relation to the laptop position?

I'm guessing what I am asking may not even be possible without a repeater somewhere.

Just finsihed writing my post and realised it could look a little suspect without a reason for this link. The wifi link is to be used when commissioning BMS control systems.
