A package allowing you to locate a 4G router at the farm buildings and beam the broadband back to the farmhouse, where it connects to a wifi router to provide superfast broadband. The wireless link requires line-of-sight between the external wireless access points, which can be placed up to 2km apart. For longer links or to dog-leg around obstructions, additional access points can be deployed as repeaters, anywhere where there's a mains supply available. For an example, see here.
Buying as a package saves £25 over the cost of buying the items individually.
