I'm not sure if I'm using the correct terminology, so please excuse me if my description is a little imprecise...
Say you have a location with internet connection and an access point for wireless devices near it... But say you want to set up another access point some number of kilometers away, utilising the first locations net connection... Is there a way to send a signal wirelessly over long range? (I'm guessing by making the signal very much directional, rather than the 360 degree signal from an access point?
