The bottom of a tower is a fantastically expensive piece of real estate
to collocate something in. If you're financing the development of such
realestate it may sound great, but if you're leasing, it is sort of
outlandish, especially if you want .5KW per ru along with it.

If you set your latency budget artificially at 1ms, at .7 C photons
travel around 210km. If you draw a circle around the base of the tower
at 75KM it's quite feasible to achieve that assuming for the sake of
argument that it's necessary.
