I remember talking to a guy who worked on an HFT firm's in-house microwave network. Sniper In Mahwah is (or at least was - I'm a little out of that world these days) pretty much bang on the mark. It's amazing what you can find out from public records, a bit of cycling and a lot of collating.

Edit: reading through some of his more recent updates I think he's still on the money
