Nice one! So you will have BB from a local Wireless Network? If that's true it could be complicated, or relatively simple depending upon how it's implemented. Does the supplier of the BB service provide any equipment for you or has he said 'go and buy some equipment'? If it's the latter then it's simple. However if he has provided a LAN cable for you to connect to them he has either supplied the router or is using an Access Point. It's all rather complicated and (a) ask your supplier (b) post back here when you know more.
