Regular "Wireless access points" (as in 802.11x) can _absolutely_ cover
this distance. All you need is a good antenna and powerful transmitter.
In America you need a license to transmit as very high powers so you
should check with your local govt. I bet if you looked around your neck
of the woods for amateur radio operators they'd be glad to explain how
to do this. There are other solutions too, like short wave radio or the
like. Using regular commodity WiFi however will be easiest to integrate
with laptops though.
