Re: I may be missing something
A directional radio link to a place with an existing high speed connection. If there is a line of sight then high speed links are easy and cheap (at least compared to laying miles of copper or fiber).
(An example - the Proxim Wireless QB-10150-LKL-WD has a range of over 10 miles and a speed of over 500 Mb/sec with a cost of under £5k for the hardware. (Not a user - this is just one of the first that popped up on a Google search.))
