Mysterious Cell Towers Infiltrate Phone Companies' Systems

Who built them? Who owns them? What might they do to your cell phone, and on whose behalf? Why are many of them near military bases? Peter van Buren at FDL: The Dissenter discusses the matter, in terms that are necessarily speculative given how little is known at present.

I can't help thinking of Sir Terry Pratchett's later Discworld novels and their clacks, a mechanical optical semaphore long-distance communication system that is the focus of many intrigues, plots and assassinations. If you're not reading Pratchett's Discworld novels, you're missing one of the most thoroughly enjoyable series out there. Call it s/f, fantasy or humor; you'd be correct with any of those categorizations. The first novel in which I remember the clacks appearing is Going Postal, and reading the later novels won't spoil the earlier ones if you choose to read about the clacks out of publication sequence. (Correction: Wikipedia says the first such novel is The Fifth Elephant.)
