It all depends on what you are travelling through. 50 miles is an effective range of a 35GHz microwave link before the earth's curvature renders that a bit impractical 2.4Ghz will happily do a miles as many RC modelers have found. Just not with trees in the way. There is an argument that scattering and destructive interference is precisely how propagation losses happen anyway... -- "In our post-modern world, climate science is not powerful because it is true: it is true because it is powerful."
